Combination Parabolic MA/IIR/ALMA Strategy, with other goodiesOkay, so this is a lot. It started mostly with me combining indicators and looking for ideal entry criteria.
It is also a collection of conditions, whether used or unused, for my current chosen "best" strategy. It is currently set how I like it, but it has changed with time, and will continue to do so. Within, there are variables that are unused, but offer some insight into the overall odds of a trade. They were, in fact, once used but fell out of favor. And all details for this strategy are within the comment header of the script.
As this evolves, I most certainly wont keep any future findings and hope for profit from my peers (yinz). Also, I'd like to give a sincere thanks to the people of TV for what I learned in a few month's time and their flexible membership plans. Basically, I'm just a mad scientist, but this monster's a masterpiece and folks here before me made many indirect contributions to it.
--------------------------
Okay guys, lastly and most importantly,
Each smack of the like button is a vote of your confidence in me, to my beautiful landladies, Celeste and Adele, that my rent will be caught up and that it won't always be a problem. Which, in my mind, makes me a graph. And they've got strong hands and don't sell the low. I more than respect that. Seriously. And I'm very grateful for their willingness to work with me, but the thing is that I didn't ask first; life just happens. But few are tolerant of others. And quite importantly, I truly believe that I will be successful one day, and that "thumbs-up" button is your vote of confidence. If you're not sure, then don't hit it yet. Maybe my scripts will boost your confidence in me :)
-------------------------
PS: And you know what? I'ma give a shout-out to Philakone for teaching me everything that I know about Elliot Wave . Absolutely. Two years ago, I would keep telling myself that one day I will put something in his gratuity wallet or pursue the paid courses. And, I still plan on it, because I'm grateful. And so also, to everybody else, I'm recommending him to learn from. because as a trader who might not know everything for free, you can certainly fill in the gaps with his altruistic offerings. And I'm betting that you will then feel more than inclined to buy the Udemy course.
"If wave 2 retraces a lot; number 4 will not". Repetition. Philakone didn't fix my memory but he sure did find a workaround, haha
Okay, everyone, Thanks!

Realized Volatility IIR Filters with BandsDISCLAIMER:

WARNING NOTICE!
THE INCLUDED FUNCTION MUST BE CONSIDERED AS TESTING. The models included in the indicator have been taken from open sources on the web and some of them has been modified by the author, problems could occur at diverse data sceneries.
WHAT'S THIS...?
Work derived by previous own research for study:
This is mainly an INFINITE IMPULSE RESPONSE FILTERING INDICATOR , it's purpose is to catch trend given by the nature of lag given by a VOLATILITY ESTIMATION ALGORITHM as it's coefficient. It provides as well an INFINITE IMPULSE RESPONSE DEVIATION FILTER that uses the same coefficients of the main filter to plot deviation bands as an auxiliary tool.
The given Filter based indicator provides my own Multi Volatility-Estimators Function with only 3 models:
ELASTIC VOLUME WEIGHTED VOLATILITY : This is a Modified Daigler & Padungsaksawasdi "Volume Weighted Volatility" as on DOI: 10.1504/IJBAAF.2018.089423 but with Elastic Volume Weighted Moving Average instead of VWAP (intraday) for faster (but inaccurate) calculation. A future version is planned on the way using intra-bar inspection for intraday timeframe as described in original paper.
GARMAN & KLASS / YANG-ZANG EXTENSION : As one of the best range based (OHLC) with open gaps inclusion in a single bar.
PETER MARTIN'S ULCER INDEX : This is a better approach to measure realized volatility than standard deviation of log returns given it's proven convex risk metric for DrawDowns as shown in Chekhlov et al. (2005) . Regarding this particular model, I take a different approach to use it as coefficient feed: Given that the UI only takes in consideration DrawDawns, I code myself the inverse of this to compute Draw-Ups as well and use both of them to filter minimums volatility levels in order to create a SLOW version of the IIR filter, and maximums of both to calculate as FAST variation. This approach can be used as a better proxy instead of any other common moving average given that with NO COMPOUND IN TIME AT ALL (N=1) or only using as long as N=3 bars of compund, the filter can catch a trend easily, making the indicator nearly a NON PARAMETRIC FILTER.

Dynamic Money FlowDynamic Money Flow is a volume indicator based on Marc Chaikin's Money Flow with a few improvements.
It can be used to confirm break-outs and trends.
Zero line crosses and divergences can provide useful signals while considering chart analysis as well.
Two weaknesses of CMF have been already fixed by Colin Twiggs (IncredibleCharts)...
1.CMF uses Chaikin's accumulation/distribution line to calculate the flow of money.
Accumulation/distribution line does not take the gaps into account. This can be solved using true range.
I call it true accumulation/distribution.
2.Oscillators have a tendency to center because of averaging calculations.
DMF is average of flowing volume divided by average of total volume. This means indicator plots the change of first factor compared to the other one. In Simple Averaging method every data is given an equal weight thus when the last data drops it will have heavy impact on the averages and the change of them.
It is much easier to identity these impacts after the drop of very high or very low data... So reducing the weight exponentially is a better option.
3.There is something else with CMF... changes of close price is ignored, because the formula only compares close price to its range.
To include the movements of close beside the close to range comparison, the distance between two last close prices should be compared to true range as well.
So volume can be distributed between close to range comparison (True Accumulation/Distribution) and close to close comparison automatically. And then results are summed to have a single multiplier.
An example for how close to close comparison affects DMF...
Or here you can see how lower wicks keep TMF (same as CMF in this case) from crossing zero line while price is trending down.
Average Daily Range (ADR) with variable look back periodThis script allows the user to change the look back period with a default of 7 periods. Fixed stops and/or profit targets can lead to risk mismanagement during high or low volatility conditions. For a particular setup, a profit target could be say 15% of the ADR and the stop at 10% of the ADR. ADR is sometimes preferred over ATR (Average True Range) as the former doesn't include gaps
Combo Backtest 123 Reversal & ECO Strategy This is combo strategies for get a cumulative signal.
First strategy
This System was created from the Book "How I Tripled My Money In The
Futures Market" by Ulf Jensen, Page 183. This is reverse type of strategies.
The strategy buys at market, if close price is higher than the previous close
during 2 days and the meaning of 9-days Stochastic Slow Oscillator is lower than 50.
The strategy sells at market, if close price is lower than the previous close price
during 2 days and the meaning of 9-days Stochastic Fast Oscillator is higher than 50.
Second strategy
We call this one the ECO for short, but it will be listed on the indicator list
at W. Blau’s Ergodic Candlestick Oscillator. The ECO is a momentum indicator.
It is based on candlestick bars, and takes into account the size and direction
of the candlestick "body". We have found it to be a very good momentum indicator,
and especially smooth, because it is unaffected by gaps in price, unlike many other
momentum indicators.
We like to use this indicator as an additional trend confirmation tool, or as an
alternate trend definition tool, in place of a weekly indicator. The simplest way
of using the indicator is simply to define the trend based on which side of the "0"
line the indicator is located on. If the indicator is above "0", then the trend is up.
If the indicator is below "0" then the trend is down. You can add an additional
qualifier by noting the "slope" of the indicator, and the crossing points of the slow
and fast lines. Some like to use the slope alone to define trend direction. If the
lines are sloping upward, the trend is up. Alternately, if the lines are sloping
downward, the trend is down. In this view, the point where the lines "cross" is the
point where the trend changes.
When the ECO is below the "0" line, the trend is down, and we are qualified only to
sell on new short signals from the Hi-Lo Activator. In other words, when the ECO is
above 0, we are not allowed to take short signals, and when the ECO is below 0, we
are not allowed to take long signals.

Candle State (The Strat)This script identifies the 2 different Candle States for use in #TheStrat.
Candle Up - The close of the current candle is greater than the close of the previous candle.
Candle Down - The close of the current candle is less than the close of the previous candle.
Though this script is extremely simple it is a teaching aid for #TheStrat.
The script also assists in the identification of up and down candles with gaps where the color of candle will not always match the Candle State.
Analysis of the candle types can help you define actionable signals and draw broadening formations.

My VWAP Reversal + Pivot Points StandardThis indicator, with the addition of a standard VWAP indicator to the 5m chart, helps the operator when using a closing candle Price to initiate a VWAP Reversal strategy.
The strategy involves Price gapping up, look for a Close below the 1st 5m candle Low; else look for a Close above the 1st 5m candle High. On a break of VWAP, take the trade in the opposite direction of the gap, hence the VWAP Reversal. Not my own strat, credit to T3 Newsbeat, publicly posted on YouTube.
The Pivot Points Standard in the Pine 4 user manual, was the base source code, and leaving it here will allow me to remove the PP indicator I was using.
HistoGapScript calculates gaps from the previous candle close to the current candle open. The computation is displayed into an histogram.
Sequentially Filtered Moving AverageThe previously proposed sequential filter aimed to filter variations lower than a certain period, this allowed to remove noisy variations and retain only the closing price values that occurred after a consecutive up/down, however because of the noisy nature of the closing price large filtering was impossible, in order to tackle to this problem the same indicator using a simple moving average as input is proposed, this allow for smoother results.
We will see that the proposed indicator can provide an alternative moving average that could be used as slow moving average in crossover systems.
The Indicator
The length parameter as the same function as the one described in the sequential filter post, however here length also control the period of the moving average used input, in short larger values of length will return a smoother but less reactive output.
In blue the moving average with length = 200, and in red the moving average with length = 50.
It is interesting to see how the moving average remain flat during ranging/flat market periods
Unfortunately like the sequential filter the sequentially filtered moving average (SFMA) is not affected by large short term variations such as gaps or short term volatile events. This is because of the nature of the sequential filter to ignore movements amplitude and only focus on the variation period.
Moving Average Crossover System
The SFMA is equal to a simple moving average of period length when a consecutive up/down sequence of size length has occurred, else the SFMA is equal to its precedent value, therefore we could expect less crosses between a fast moving average and the SFMA as slow moving average.
We can see on the figure above that the fast moving average of period 50 (in green) cross more with the slow moving average of period 200 (in red) than with the SFMA of period 200 (in blue).
Crosses can occur at the same time as with the classical slow moving average (in red) or a bit later.
Conclusion
A new moving average based on the recently proposed sequential filter has been proposed, it can be seen that under a moving average crossover system the proposed moving average seems to be more effective at producing less crosses without necessarily doing it with an excessive lag, in fact the moving average has either lag (length-1)/2 or lag length .
In the future it could be interesting to provide an hybrid alternative that take into account volatility as well as variations period.

Sequential Filter - An Original Filtering ApproachRemoving irregular variations in the closing price remain a major task in technical analysis, indicators used to this end mostly include moving averages and other kind of low-pass filters. Understanding what kind of variations we want to remove is important, irregular (noisy) variations have mostly a short term period, fully removing them can be complicated if the filter is not properly selected, for example we might want to fully remove variations with a period of 2 bars and lower, if we select an arithmetic moving average the filter output might still contain such variations because of the ripples in the frequency response passband, all it would take is a variation of high amplitude for that variation to be clearly visible.
Although all it would take for better filtering is a filter with better performance in the frequency domain (gaussian, Butterworth, Bessel...) we can design innovative approaches that does not rely on the model of classical moving averages, today a new technical indicator is proposed, the technical indicator fully remove variations lower than the selected period.
The Indicator Approach
In order for the indicator output to change the closing price need to produce length consecutive up's/down's, length control the variation threshold of the indicator, variations lower than length are fully removed. Lets see a visual example :
Here length = 3, the closing price need to make 3 consecutive up's/down's, when the sequence happen the indicator output is equal to src , here the closing price, else the indicator is equal to its precedent value, hence removing other variations. The value of 3 is the value by default, this is because i have seen in the past that the average smallest variations period where in general of 3 bars.
Because the indicator focus only on the variation sign, it totally ignore the amplitude of the movement, this provide an effective way to filter short term retracement in a fluctuation as show'n below :
The candle option of the indicator allow the indicator to only focus on the body color of a candle, thus ignoring potential gaps, below is an example with the candle option off :
If we activate the "candle" option we end up with :
Note that the candle option is based on the closing and opening price, if you use the indicator on another indicator output make sure to have the candle option off.
Length and Indicator Color
The closing price is infected by noise, and will rarely make a large sequence of consecutive up's/down's, the indicator can therefore be useful to detect consecutive sequence of length period, here 6 is selected on BTCUSD :
A consecutive up's/down's of period 6 can be considered a relatively rare event.
It is important to note that the color of the indicator used by default has nothing to do with the consecutive sequence detected, that is the indicator turning red doesn't necessarily mean that a consecutive down's sequence has occurred, but only that this sequence has occurred at a lower value than the precedent detected sequence. This is show'n below :
In order to make the indicator color based on the detected sequence check the "Color Based On Detected Sequence" option.
Conclusion
An original approach on filtering price variations has been proposed, i believe the indicator code is elegant as well as relatively efficient, and since high values of length can't really be used the indicator execution speed will remain relatively fast.

Currency Strength ALT v1.0Description:
This study is a version of Currency Strength Meter, that utilises TradingViews built-in 8 Currency indices (?XY), rather calculate them from currency pair values. It also utilises the built-in TSI function, the TSI uses moving averages of the underlying momentum of a financial instrument. The advantage of using the Currency Indices for strength is the fact that they are based on multiple Exchange sources and so hopefully making it more representative.
***WARNING*** The TradingView Currency Indices do tend to have gaps between candles especially on the low volume currencies like NZD and AUD, so strength chart can also jump around. I suggest using the indicator with higher TF (4H+) charts.
Setting-Less Trend-Step FilteringIntroduction
Indicators settings have been a major concern in trading strategies, in order to provide the best results each indicators involved in the strategy must have its settings optimized, when using only 1 indicator this task can easily be achieved, but an increasing number of indicators involve more slower computations, lot of softwares will use brute force for indicators settings optimization, this involve testing each indicator settings and see which setting/combination maximize the equity, in order to fasten this process softwares can use a user defined range for the indicator settings. Nonetheless the combination that maximize the equity at time t might be different at time t+1...n .
Therefore i propose an indicator without any numerical setting that aim to filter small price variations using the architecture of the T-step lsma, such indicator can provide robust filtering and can therefore be used as input for other indicators.
Robustness Vs Non Robustness
Robustness is often defined as the ability of certain statistical tools to be less affected by outliers, outliers are defined as huge variations in a data-set, high volatility movements and large gaps might be considered as outliers. However here we define robustness as the ability of an indicator to be non affected by price variations that are not correlated with the main trend, which can be defined in technical analysis as pullbacks.
Some small pullbacks in INTEL, the indicator is not affected by them, which allow the indicator to filter the price in a "smart" way.
This effect is made possible by using exponential averaging in the indicator, exponential averaging is defined as y = sc*x + (1-sc)*y , with 1 > sc > 0 . Here sc is calculated in a similar way as the kalman gain, which is in the form of a/(a + b) , in our case this is done with :
sc = abs(input - nz(b ))/(abs(input - nz(b )) + nz(a ))
Non Robust Version Of The Indicator
The user is allowed to use the non robust version of the indicator by unchecking "robust" in the setting panel, this allow a better fit with the price at the cost of less filtering.
robust checked
robust unchecked
Conclusion
I proposed a technical indicator that aim to filter short frequencies without the use of parameters, the indicator proven to be robust to various pullbacks and therefore was able to follow the main trend, although using the term trend for such small price variations might be wrong. Removing high frequencies is always beneficial in trading, noisy series are harder to manipulate, this is why you'll see a lot of indicators using median price often defined as hl2 instead of the closing price.
Like previous settings-less indicators i published this one can behave differently depending on the time frame selected by the user, lower time frames will make the indicator filter more. I'll try to make more setting-less indicators that will correct this effect.

[RESEARCH] Heikin-Ashi Chart IdentifierA deterministic approach to identify Heikin-Ashi chart type.
The script checks the next statements about HA:
HA chart does not have any gaps in a classic sense
Every new HA open price is calculated using a specific recurrence formula. This fact also means that initial HA open price is used to calculate all the next and so on (a construction of Infinite Impulse Response filters)
The script works correctly being applied to other chart types:

Volume Profile Free Pro (25 Levels Value Area VWAP) by RRBVolume Profile Free Pro by RagingRocketBull 2019
Version 1.0
All available Volume Profile Free Pro versions are listed below (They are very similar and I don't want to publish them as separate indicators):
ver 1.0: style columns implementation
ver 2.0: style histogram implementation
ver 3.0: style line implementation
This indicator calculates Volume Profile for a given range and shows it as a histogram consisting of 25 horizontal bars.
It can also show Point of Control (POC), Developing POC, Value Area/VWAP StdDev High/Low as dynamically moving levels.
Free accounts can't access Standard TradingView Volume Profile, hence this indicator.
There are 3 basic methods to calculate the Value Area for a session.
- original method developed by Steidlmayr (calculated around POC)
- classical method using StdDev (calculated around the mean VWAP)
- another method based on the mean absolute deviation (calculated around the median)
POC is a high volume node and can be used as support/resistance. But when far from the day's average price it may not be as good a trend filter as the other methods.
The 80% Rule: When the market opens above/below the Value Area and then returns/stays back inside for 2 consecutive 30min periods it has 80% chance of filling VA (like a gap).
There are several versions: Free, Free Pro, Free MAX. This is the Free Pro version. The Differences are listed below:
- Free: 30 levels, Buy/Sell/Total Volume Profile views, POC
- Free Pro: 25 levels, +Developing POC, Value Area/VWAP High/Low Levels, Above/Below Area Dimming
- Free MAX: 50 levels, packed to the limit
Features:
- Volume Profile with up to 25 levels (3 implementations)
- POC, Developing POC Levels
- Buy/Sell/Total/Side by Side View modes
- Side Cover
- Value Area, VAH/VAL dynamic levels
- VWAP High/Low dynamic levels with Source, Length, StdDev as params
- Show/Hide all levels
- Dim Non Value Area Zones
- Custom Range with Highlighting
- 3 Anchor points for Volume Profile
- Flip Levels Horizontally
- Adjustable width, offset and spacing of levels
- Custom Color for POC/VA/VWAP levels and Transparency for buy/sell levels
Usage:
- specify max_level/min_level for a range (required in ver 1.0/2.0, auto/optional in ver 3.0 = set to highest/lowest)
- select range (start_bar, range length), confirm with range highlighting
- select mode Value Area or VWAP to show corresponding levels.
- flip/select anchor point to position the buy/sell levels, adjust width and spacing as needed
- select Buy/Sell/Total/Side by Side view mode
- use POC/Developing POC/VA/VWAP High/Low as S/R levels. Usually daily values from 1-3 days back are used as levels for the current day.
- Green - buy volume of a specific price level in a range, Red - sell volume. Green + Red = Total volume of a price level in a range
There's no native support for vertical histograms in Pinescript (with price axis as base)
Basically, there are 4 ways to plot a series of horizontal bars stacked on top of each other:
1. plotshape style labeldown (ver 0 prototype discarded)
- you can have a set of fixed width/height text labels consisting of a series of underscores and moving dynamically as levels. Level offset controls visible length.
- you can move levels and scale the base width of the volume profile histogram dynamically
- you can calculate the highest/lowest range values automatically. max_level/min_level inputs are optional
- you can't fill the gaps between levels/adjust/extend width, height - this results in a half baked volume profile and looks ugly
- fixed text level height doesn't adjust and looks bad on a log scale
- fixed font width also doesn't scale and can't be properly aligned with bars when zooming
2. plot style columns + hist_base (ver 1.0)
- you can plot long horizontal bars using a series of small adjacent vertical columns with level offsets controlling visible length.
- you can't hide/move levels of the volume profile histogram dynamically on each bar, they must be plotted at all times regardless - you can't delete the history of a plot.
- you can't scale the base width of the volume profile histogram dynamically, can't set show_last from input, must use a preset fixed width for each level
- hist_base can only be a static const expression, can't be assigned highest/lowest range values automatically - you have to specify max_level/min_level manually from input
- you can't control spacing between columns - there's an equalizer bar effect when you zoom in, and solid bars when you zoom out
- using hist_base for levels results in ugly load/redraw times - give it 3-5 sec to finalize its shape after each UI param change
- level top can be properly aligned with another level's bottom producing a clean good looking histogram
- columns are properly aligned with bars automatically
3. plot style histogram + hist_base (ver 2.0)
- you can plot long horizontal bars using a series of small vertical bars (horizontal histogram) instead of columns.
- you can control the width of each histogram bar comprising a level (spacing/horiz density). Large enough width will cause bar overlapping and give level a "solid" look regardless of zoom
- you can only set width <= 4 in UI Style - custom textbox input is provided for larger values. You can set width and plot transparency from input
- this method still uses hist_base and inherits other limitations of ver 2.0
4. plot style lines (ver 3.0)
- you can also plot long horizontal bars using lines with level offsets controlling visible length.
- lines don't need hist_base - fast and smooth redraw times
- you can calculate the highest/lowest range values automatically. max_level/min_level inputs are optional
- level top can't be properly aligned with another level's bottom and have a proper spacing because line width uses its own units and doesn't scale
- fixed line width of a level (vertical thickness) doesn't scale and looks bad on log (level overlapping)
- you can only set width <= 4 in UI Style, a custom textbox input is provided for larger values. You can set width and plot transparency from input
Notes:
- hist_base for levels results in ugly load/redraw times - give it 3-5 sec to finalize its shape after each UI param change
- indicator is slow on TFs with long history 10000+ bars
- Volume Profile/Value Area are calculated for a given range and updated on each bar. Each level has a fixed width. Offsets control visible level parts. Side Cover hides the invisible parts.
- Custom Color for POC/VA/VWAP levels - UI Style color/transparency can only change shape's color and doesn't affect textcolor, hence this additional option
- Custom Widh for levels - UI Style supports only width <= 4, hence this additional option
- POC is visible in both modes. In VWAP mode Developing POC becomes VWAP, VA High and Low => VWAP High and Low correspondingly to minimize the number of plot outputs
- You can't change buy/sell level colors (only plot transparency) - this requires 2x plot outputs exceeding max 64 limit. That's why 2 additional plots are used to dim the non Value Area zones
- Use Side by Side view to compare buy and sell volumes between each other: base width = max(total_buy_vol, total_sell_vol)
- All buy/sell volume lengths are calculated as % of a fixed base width = 100 bars (100%). You can't set show_last from input
- Sell Offset is calculated relative to Buy Offset to stack/extend sell on top of buy. Buy Offset = Zero - Buy Length. Sell Offset = Buy Offset - Sell Length = Zero - Buy Length - Sell Length
- If you see "loop too long error" - change some values in UI and it will recalculate - no need to refresh the chart
- There's no such thing as buy/sell volume, there's just volume, but for the purposes of the Volume Profile method, assume: bull candle = buy volume, bear candle = sell volume
- Volume Profile Range is limited to 5000 bars for free accounts
P.S. Cantaloupia Will be Free!

Repainting? Yes/NoSuppose, you'd like to avoid repainting issues in your scripts. How to achieve this?..
If you do not use `security` function, then simply calculate only on confirmed (closed) bars. Use either `close ` as a source or/and `barstate.isconfirmed` variable in your logic.
But if you use `security` to get data of a higher timeframe, then what? In such a case to get the same result - use `security` with
* `lookahead` param switched ON
* in `expr` param use "square brackets of 1" - previous bar value of your signal (`data` variable is your "signal").
NOTE 1: that `gaps` param doesn't affect repainting in any way.
NOTE 2: `lookahead` param when switched OFF affects the `security` behaviour only on history data. And indicator still repaints (realtime calculations change after chart reload).
In my example, script uses 5 minute closed bars (that means they will not change after chart reload, so there will be no repainting) on 1 minute chart.
Plots that "repaint" are hidden. You may make them visible to see how they look like.
Zero Lag Money Flow [jwammo12]This indicator adds Zero Lag principles to a modified Chaikin Money Flow.
This is essentially the Chaikin Money Flow indicator that uses true range to remove the issues that arise from gaps that the original CMF algorithm had. Then, momentum is used to remove lag from the indicator.
The Lag parameter is the lookback used for the momentum component
Rogers & Satchell Volatility EstimationFirst off, a huge thank you to the following people:
theheirophant: www.tradingview.com
alexgrover: www.tradingview.com
NGBaltic: www.tradingview.com
The Rogers & Satchell function is a volatility estimator that outperforms other estimators when the underlying follows a geometric Brownian motion with a drift (historical data mean returns different from zero). As a result, it provides a better volatility estimation when the underlying is trending. However, the Rogers & Satchell estimator does not account for jumps in price (gaps). It assumes no opening jump. The function uses the open, close, high, and low price series in its calculation and it has only one parameter, which is the period to use to estimate the volatility.
This script allows you to transform the volatility reading. The intention of this is to be able to compare volatility across different assets and timeframes. Having a relative reading of volatility also allows you to better gauge volatility within the context of current market conditions.
For the signal lie I chose a repulsion moving average to remove choppy crossovers of the estimator and the signal. This may have been a mistake, so in the near-future I might update so that the MA can be selected. Let me know if you have any opinions either way.

Gap Measure PercentA measure of the gaps (bullish or bearish) in an instrument based on percentage change relative to current price.
Layering PlotsLets say you want to layer into a position and you'd like to see it turn around. The study lets you set a baseline and increments above and below that baseline. A green cross is plotted ever time the price crosses above one of the increments, and red when crossing below that increment.
In the example I set the baseline to $22.1, and Layer increments to $0.50. So it will plot a cross every 50 cents above and below the baseline. This can be used on any chart period (daily, hourly, 5min...), but is limited to 9 layers above and below the baseline.
NOTES...
Lime = when price crosses above a layer that is above the baseline
Green = when price crosses above a layer below the baseline
Pink = when price crosses below a layer that is above the baseline
Red = when price crosses below a layer below the baseline
IMPORTANT...
This does not plot sometimes. I'm using a crossover crossunder function, and if a candle gaps open below and ends above a layer, this will not plot. It is not in error, just the way that function works. I will be looking to improve this study, wanted to share what I have for now.
Simple TrenderOriginates from:
I was reading some Impulse Trading literature by A. Elder.. In it, someone named Kerry Lovvorn proposed "An End of Day Trend Following System" for someone lazy.
Originally it is just price closing above an 8 ema (low) for long. Exit when price closes below an 8 ema (low). The opposite for a short position.
Conditions: Buy when price closed below ema (low) for two bars or more, then closes above. Opposite for a short position. I do not follow this condition. Though it may help with whipsaw.
My condition is when price closes above the 26 ema (low) (works the best for me) I place orders above the initial crossing bars high. Opposite for lows.
I look for stocks that are low in price to go long on. I want the run from 2's to 15's
I look for stocks that are mid-teens/20's in price to go short on. I want the run from 20's to 2's
I look for stock with news and earnings that are already running (up or down) to play the pullback.
These conditions can easily be scanned for on thinkorswim
From first glance, the system looks like CMsling shotsystem. Although, I plagiarized some parts of the codes, because I am inept when it comes to that shit, it differs as it is not a moving average crossover system.
It is a price crossing over concept. A moving average VWAP is used for best entries on pullbacks.
Purpose:
--To catch the majority of a trend/wave/run.
--To identify pullback areas to go long or short while in midst of trend. To catch pullbacks off news and earning runners.
--To catch the initial start of trend with clear rules to enter
--Clear rules to exit
Issues
--possibilities of getting ninja sliced the fuck up. Can be mitigated by entering stocks with decent average volume. And also only going long above 200 ema and short below it. ADX won't work, at the initial start of the trend it will show not trending. Can look at blow off volume at the bottom followed by increase in buying for long and vice versa for short.
--Can give some huge gains away through gap ups or gap downs from news or earnings during trend. However, can get huge gain on gaps from news or earning. Nature of the game.
--Need some brass balls and a supply of pepto to stomach through some of the pullbacks. Gut wrenching seeing big gains dwindle. But they all even out at the end, you hope. (see NBEV and IGC, and CRON and others. shit don't go in straight lines, homie)
Pros
--It's simple and easy. Overall, you profit
--works with any security
Cons
--It can be stressful.
--does not work well on lower time frames. Do not recommend going below 15 minutes
--Possibility of working on 5 minutes with a time frame breakout strategy (15,30 min).
Couple it with LazyBear "Weis Wave Volume" indicator. Works well for pullback entries.
Enjoy. Ride some waves.
