MACD_VXI by GermoIts a volume-weighted MACD(13/21), by applying VW(8) to the MA formula.
Not a big deal, but I liked it. It reduces some noise imho.
neutronix community bot ML + Alerts 4h-daily (mod. capissimo)Gm traders,
i have been a python programmer for some years studying artificial intelligence for general purpose; after some time i finally decided to have a look at some finance related stuff and scripts.
Moved by curiosity i've decided to make some but decisive modifications to a script i tried to use initially but without success: the LVQ machine learning strategy.
So after studying the charts and indicators, i have rewritten this script made by Capissimo and added heavy filtering thanks to vwap and vwma, then fixed repaint and other issues.
I hope you enjoy it and that it could increase your possibilities of success in trading.
HOW TO USE THE SCRIPT
Add the script to 3h+ charts like for example BTC 4h, 6h, 8h, 12h, daily. (In order for it to work on shorter timeframes charts you can try to change to lookback window but i dont advise it).
Change only rsi and volfilter(volume filtering) settings to try to find the best winrate. Leave dataset to open. Fyi the winrate isn't 100% accurate but can give you a raw vision of final results.
Use alerts included for trading and and in options click on 'Once per bar'. If you have checked 'Reverse Signals' in the control panel you have got more 'risky' signals so be advised if trading futures and stocks.
Exit trade signals not provided, so it is recommended the use of take profits and stop loss (1.5:1 ratio)
As always, the script is for study purposes. Do not risk more than you can spend!

ADR: Average Daily RangeVery basic script... adjust the EMA to 13 for stocks, and less volatile assets. 26 for crypto, and anything highly volatile.
When the Daily Low line (bottom yellow/orange line) dips hard, and finds support for 3+ bars somewhere, this is a sign of a trend reversal. For a solid confirmation, wait for the Super Average and EMA to spike downwards as well. All of this can also be seen as reversal at the top of a trend, just upturned.
The 2 Daily lines (2 yellow/orange lines) act as support for the price to bounce off of. Fine tuning is required to get these really smooth, but it's a simple enough idea.
Edit: Screwed up the EMA in my posted example. Should be 26.
AP Index - Geomagnetic disturbancesDaily AP index back to 2015-01-01.
Geomagnetic disturbances can be monitored by ground-based magnetic observatories recording the three magnetic field components. The global Kp index is obtained as the mean value of the disturbance levels in the two horizontal field components, observed at 13 selected, subauroral stations . The name Kp originates from "planetarische Kennziffer" ( = planetary index).
The three-hour index ap and the daily indices Ap, Cp and C9 are directly related to the Kp index. In order to obtain a linear scale from Kp, J. Bartels gave the following table to derive a three-hour equivalent range, named ap index.
Geomagnetic Ap Index: The daily index Ap is obtained by averaging the eight values of ap for each day.
Based on the data from Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences.
PBK Trend BandThis is providing a trend detection tool and a trend band display to identify possible trend reversal points using EMAs.
Some seem to like using 13 and 26.
I prefer 5 and 15, like PET-D from Steve Primo which react faster and avoid being kicked by some fast move (happens in crypto, see Litecoin...).
PI_GRM Bitcoin Golden Ratio Multipier [wozdux]Golden Ratio Multiplier

[EG] Fib RSIExtrapolated Fibonacci MA (FMA) into an RSI
i.e. FMA(up) and FMA(dn) of lengths 2, 3, 5, 8, 13, 21, 34, 55, 89 etc. averaged into RSI values.
Keep in mind it does not use 'Length' - it uses 'Interval' - how many fib intervals to include in the RSI calculation.
I threw in Ehler's Smoothing as well - seems to work quite well, thanks to TV Community for inspiration and code to look at for help
(Standard RSI included for comparison)
Fibonacci Moving AverageSimple idea from an article I read online I decided to code:
Take EMA's for periods based on the fibonacci sequence - 3, 5, 8, 13, 21, 34, 55 etc. and average them into one MA - the result is the Fibonacci MA (FMA)
Therefore - note the FMA does not use Length - but Range/Interval of how many steps of the Fibonacci Sequence to include.
Seems to be good for finding support/resistance for the price - so added some extra features:
Using up to 3 in at different periods - when they stretch apart it means price is very deviated and will reverse.
Added a price OHLC line if you want to move the indicator to a sub-panel for nice visualisation.
I believe you could look at the 4, 8 and 10, where the longest MA (10,11 FMA) indicates overall bull or bear trend (whether on top or bottom) and you could probably code in alerts for price crossing up or crossing down on the faster (4 FMA)
Relative Volume Screener AlertsThis script will screen 12 different stocks and current chart (13 in total) for entry points from my relative volume indicator.
1. Enter in any ticker ID's from charts you wish to scan in the settings.
2. Go to desired timeframe.
3. Click add alert button at top toolbar.
4. Select RVOL Screener Alerts indicator, input alert notification settings and/or change alert name and click create.
The script will then scan the stocks and alert you of any entry points from the timeframe you set the alerts.
A new alert needs to be created for each timeframe you wish to screen.
You can find my relative volume indicator here:
Keltner TrendThis indicator takes the concept of Keltner Channels and uses them as a trend following system by using a deviation band of 1 ATR, such that when the price closes above the upper band a bull trend is predicted to follow, and when the price closes below the lower band the start of a bear trend is assumed.
Only 1 band is plotted at all times depending on the bias of the trend.
Default settings are a 21 EMA as a centerline with a 13 period ATR.
Enjoy!

QFL 13 BasesThis version of QFL is based on a script from ralphhorkup:
Author:
www.tradingview.com
I made a few adjustments:
1) no issues with repainting caused by calling security function.
2) migrated to pine script 4
Everything else is the same.
I'll be adding alerts soon.
Volatility OscillatorThis tool displays relative volatility and directional trend. Excellent way to pickup diversions and reversals. Length can be lowered to 11 or 13 in settings to show price range.
Can be used to identify patterns such as parallel channels and likely direction of price action as pictured below.
Alt IndexBased off of the original from LucF, this modifcation updates the list of alts and reduces the number to 13 for faster loading.
Zig Lines with Percent & ValueOverview, Features, and Usage:
The Zig Lines with Percent & Value is an indicator that highlights the highest and lowest points of the market from pivot points and zigzag lines based on the ZigZag Period setting. By a default value of 13 for the ZigZag Period this works well on Bitcoin or other alt coins on the 1 hour or higher timeframe charts.
What makes this indicator unique is that it draws a green line to signify an uptrend or a red line to signify a down trend. It will also show the percent difference between the previous point/line, for example: If you see a -negative percentage point with a red line drawn to it, then you are looking at a low pivot point and then as the green line is drawn to a +positive percentage value the percentage you see is the difference between the two points. This is great to see a trend reversal as you can look at previous pivot points and notice about how far the price moves before it changes direction (trend reversal).
There is an invisible EMA line that is used to assist with coloring the negative vs positive values. The value above or below the percentage is the lowest or highest price at that pivot point . The display of the price at the pivot point depends on your ZigZag Period setting and the timeframe of your chart.
Added Bollinger Bands as it fits perfectly with the visuals of the Zig Lines & Pivots.
Usage of Bollinger Bands:
~As the price or candle gets close to the top or bottom of the Bollinger band it can give you a better confirmation that the pivot location is at it's final place, and the trend is more likely to switch directions.
It’s important to know this indicator should not be used for alerts of any type it does repaint as the green or red line is drawing based on live chart data and it can change depending on the direction of the market. This is a great visual tool for trend analysis or to be used with other indicators as a confirmation for a possible good entry or exit position.

OM Session RangesThis indicator was created to assist in generating the morning and afternoon ranges as defined by Options Millionaire's strategy.
Morning range is determined by identifying the high and low from open to 10:05.
Afternoon range is determined by identifying the high and low from 13:30 to 14:05.
Customizable Daily EMAs (up to 8)This indicator provides you with up to 8 different EMAs that are customizable.
You can specify how many EMAs you want on the chart (up to a maximum of 8), as well as the length and color of each EMA. In addition, the resolution of all EMAs can also be customized - by default all EMAs follow the Daily timeframe but you could set this to any timeframe you want or you could choose for it to follow the timeframe chart as most other EMA Indicators do.
The reason for creating this indicator is because I was looking for Daily EMAs, but wanted to view the chart in a different time period without the EMA lines themselves changing. In addition, I wanted to view ample EMAs at once, and have the ability to change their length as I see fit.
You can see this demonstrated on the 4-hour chart above. Despite the chart being a 4 hourly chart, the EMAs are Daily EMAs.
In the example above all 8 EMAs have been activated, but you could turn any of these off to suit your own preferences.
The default EMAs are set to the following: 20, 50, 100, 200, 5, 9, 13, 26.
The First 4 are ideal for longer-term targets, while the smaller timeframes are more suited to short-term trading targets.
I have made this script Open-source for anybody to view, copy and modify if they need.
Financial Astrology Moon LongitudeMoon energy represent the masses, crowds, public places, children and emotions. The transit of the Moon through the zodiacal signs will color the crowd emotional responses that fluctuate based on the elemental qualities of the signs: fire (energetic and impulsive), earth (rigid, static, patient), water (assimilation, transformation, humor fluctuations), air (expansion, fervent, germination).
The daily average speed of the Moon is 13 degrees, for this reason the emotional elemental energy is transforming in average every 2 days and few hours, this mood fluctuations produces the short term instinctive and emotional actions performed by traders that forget the precise mathematical / statistical approach in favor of irrational and emotional impulses.
Based on statistical buy/sell frequency analysis we discovered that for BTC-USD, the Moon is usually bullish in zodiac signs: Aries, Libra, Scorpio, Aquarius and Pisces, the most relevant bullish sign is "Aquarius", from 206 observations in all the BTC-USD price history where Moon was in this sign the 60% of those days the price increased compared to the previous day. The bearish zodiac signs for BTC-USD are: Taurus, Cancer, Leo, Sagittarius and Capricorn, the most relevant bearish sign is "Capricorn".
Interestingly this zodiac sign locations tends to fluctuate during some periods of time and from the last 10 observations of the Moon transiting through Aries we noted that 7 of the 10 observations coincide with a dip, sometimes the Moon in Aries indicate the reversal of the short term trend, this is kind of expected considering that when Moon approaches Taurus the fall becomes more likely due to the fact that Moon in Taurus is a bearish signal.
With this indicator there is unlimited possibilities to explore across different markets and complementing with Moon phases this may be the perfect financial astrology indicator for those intraday traders that keep positions only for few hours.
We encourage you to analyze the Moon zodiac sign cycles in different markets and share with us your observations, leave us a comment with your research outcomes. Happy trading!
Note: The Moon longitude indicator is based on an ephemeris array that covers years 2010 to 2030, prior or after this years the longitude is not available, this daily ephemeris are based on UTC time so in order to align properly with the price bars times you should set UTC as your chart reference timezone.
Combo Backtest 123 Reversal & RAVI 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
The indicator represents the relative convergence/divergence of the moving
averages of the financial asset, increased a hundred times. It is based on
a different principle than the ADX. Chande suggests a 13-week SMA as the
basis for the indicator. It represents the quarterly (3 months = 65 working days)
sentiments of the market participants concerning prices. The short moving average
comprises 10% of the one and is rounded to seven.

Realtime Delta Volume Action [LucF]█ OVERVIEW
This indicator displays on-chart, realtime, delta volume and delta ticks information for each bar. It aims to provide traders who trade price action on small timeframes with volume and tick information gathered as updates come in the chart's feed. It builds its own candles, which are optimized to display volume delta information. It only works in realtime.
█ WARNING
This script is intended for traders who can already profitably trade discretionary on small timeframes. The high cost in fees and the excitement of trading at small timeframes have ruined many newcomers to trading. While trading at small timeframes can work magic for adrenaline junkies in search of thrills rather than profits, I DO NOT recommend it to most traders. Only seasoned discretionary traders able to factor in the relatively high cost of such a trading practice can ever hope to take money out of markets in that type of environment, and I would venture they account for an infinitesimal percentage of traders. If you are a newcomer to trading, AVOID THIS TOOL AT ALL COSTS — unless you are interested in experimenting with the interpretation of volume delta combined with price action. No tool currently available on TradingView provides this type of close monitoring of volume delta information, but if you are not already trading small timeframes profitably, please do not let yourself become convinced that it is the missing piece you needed. Avoid becoming a sucker who only contributes by providing liquidity to markets.
The information calculated by the indicator cannot be saved on charts, nor can it be recalculated from historical bars.
If you refresh the chart or restart the script, the accumulated information will be lost.
█ FEATURES
Key values
The script displays the following key values:
• Above the bar: ticks delta (DT), the total ticks for the bar, the percentage of total ticks that DT represents (DT%)
• Below the bar: volume delta (DV), the total volume for the bar, the percentage of total volume that DV represents (DV%).
Candles
Candles are composed of four components:
1. A top shaped like this: ┴, and a bottom shaped like this: ┬ (picture a normal Japanese candle without a body outline; the values used are the same).
2. The candle bodies are filled with the bull/bear color representing the polarity of DV. The intensity of the body's color is determined by the DV% value.
When DV% is 100, the intensity of the fill is brightest. This plays well in interpreting the body colors, as the smaller, less significant DV% values will produce less vivid colors.
3. The bright-colored borders of the candle bodies occur on "strong bars", i.e., bars meeting the criteria selected in the script's inputs, which you can configure.
4. The POC line is a small horizontal line that appears to the left of the candle. It is the volume-weighted average of all price updates during the bar.
Calculations
This script monitors each realtime update of the chart's feed. It first determines if price has moved up or down since the last update. The polarity of the price change, in turn, determines the polarity of the volume and tick for that specific update. If price does not move between consecutive updates, then the last known polarity is used. Using this method, we can calculate a running volume delta and ticks delta for the bar, which becomes the bar's final delta values when the bar closes (you can inspect values of elapsed realtime bars in the Data Window or the indicator's values). Note that these values will all reset if the script re-executes because of a change in inputs or a chart refresh.
While this method of calculating is not perfect, it is by far the most precise way of calculating volume delta available on TradingView at the moment. Calculating more precise results would require scripts to have access to tick data from any chart timeframe. Charts at seconds timeframes do use exchange/broker ticks when the feeds you are using allow for it, and this indicator will run on them, but tick data is not yet available from higher timeframes. Also, note that the method used in this script is far superior to the intrabar inspection technique used on historical bars in my other "Delta Volume" indicators. This is because volume and ticks delta here are calculated from many more realtime updates than the available intrabars in history. Unfortunately, the calculation method used here cannot be used on historical bars, where intrabar inspection remains, in my opinion, the optimal method.
Inputs
The script's inputs provide many ways to personalize all the components: what is displayed, the colors used to display the information, and the marker conditions. Tooltips provide details for many of the inputs; I leave their exploration to you.
Markers
Markers provide a way for you to identify the points of interest of your choice on the chart. You control the set of conditions that trigger each of the five available markers.
You select conditions by entering, in the field for each marker, the number of each condition you want to include, separated by a comma. The conditions are:
1 — The bar's polarity is up/dn.
2 — `close` rises/falls ("rises" means it is higher than its value on the previous bar).
3 — DV's polarity is +/–.
4 — DV% rises (↕).
5 — POC rises/falls.
6 — The quantity of realtime updates rises (↕).
7 — DV > limit (You specify the limit in the inputs. Since DV can be +/–, DV– must be less than `–limit` for a short marker).
8 — DV% > limit (↕).
9 — DV+ rises for a long marker, DV– falls for a short.
10 — Consecutive DV+/DV– on two bars.
11 — Total volume rises (↕).
12 — DT's polarity is +/–.
13 — DT% rises (↕).
14 — DT+ rises for a long marker, DT– falls for a short.
Conditions showing the (↕) symbol do not have symmetrical states; they act more like filters. If you only include condition 4 in a marker's setup, for example, both long and short markers will trigger on bars where DV% rises. To trigger only long or short markers, you must add a condition providing directional differentiation, such as conditions 1 or 2. Accordingly, you would enter "1,4" or "2,4".
For a marker to trigger, ALL the conditions you specified for it must be met. Long markers appear on the chart as "Mx▲" signs under the values displayed below candles. Short markers display "Mx▼" over the number of updates displayed above candles. The marker's number will replace the "x" in "Mx▲". The script loads with five markers that will not trigger because no conditions are associated with them. To activate markers, you will need to select and enter the set of conditions you require for each one.
Alerts
You can configure alerts on this script. They will trigger whenever one of the configured markers triggers. Alerts do not repaint, so they trigger at the bar's close—which is also when the markers will appear.
█ HOW TO USE IT
As a rule, I do not prescribe expected use of my indicators, as traders have proved to be much more creative than me in using them. Additionally, I tend to think that if you expect detailed recommendations from me to be able to use my indicators, it's a sign you are in a precarious situation and should go back to the drawing board and master the necessary basics that will allow you to explore and decide for yourself if my indicators can be useful to you, and how you will use them. I will make an exception for this thing, as it presents fairly novel information. I will use simple logic to surmise potential uses, as contrary to most of my other indicators, I have NOT used this one to actually trade. Markets have a way of throwing wrenches in our seemingly bullet-proof rationalizing, so drive cautiously and please forgive me if the pointers I share here don't pan out.
The first thing to do is to disable your normal bars. You can do this by clicking on the eye icon that appears when you hover over the symbol's name in the upper-left corner of your chart.
The absolute value and polarity of DV mean little without perspective; that's why I include both total volume for the bar and the percentage that DV represents of that total volume. I interpret a low DV% value as indecision. If you share that opinion, you could, let's say, configure one of the markers on "DV% > 80%", for example (to do so you would enter "8" in the condition field of any marker, and "80" in the limit field for condition 8, below the marker conditions).
I also like to analyze price action on the bar with DV%. Small DV% values should often produce small candle bodies. If a small DV% value occurs on a bar with much movement and high volume, I'm thinking "tough battle with potential explosive power when one side wins". Conversely, large bodies with high DV% mean that large volume is breaching through multiple levels, or that nobody is suddenly willing to take the other side of a normal volume of trades.
I find the POC lines really interesting. First, they tell us the price point where the most significant action (taking into account both price occurrences AND volume) during the bar occurred. Second, they can be useful when compared against past values. Third, their color helps us in figuring out which ones are the most significant. Unsurprisingly, bunches of orange POCs tend to appear in consolidation zones, in pauses, and before reversals. It may be useful to often focus more on POC progression than on `close` values. This is not to say that OHLC values are not useful; looking, as is customary, for higher highs or lower lows, or for repeated tests of precise levels can of course still be useful. I do like how POCs add another dimension to chart readings.
What should you do with the ticks delta above bars? Old-time ticker tape readers paid attention to the sounds coming from it (the "ticker" moniker actually comes from the sound they made). They knew activity was picking up when the frequency of the "ticks" increased. My thinking is that the total number of ticks will help you in the same way, since increasing updates usually mean growing interest—and thus perhaps price movement, as increasing volatility or volume would lead us to surmise. Ticks delta can help you figure out when proportionally large, random orders come in from traders with other perspectives than the short-term price action you are typically working with when you use this tool. Just as volume delta, ticks delta are one more informational component that can help you confirm convergence when building your opinions on price action.
What are strong bars? They are an attempt to identify significance. They are like a default marker, except that instead of displaying "Mx▲/▼" below/above the bar, the candle's body is outlined in bright bull/bear color when one is detected. Strong bars require a respectable amount of conditions to be met (you can see and re-configure them in the inputs). Think of them as pushes rather than indications of an upcoming, strong and multi-bar move. Pushes do, for sure, often occur at the beginning of strong trends. You will often see a few strong bars occur at 2-3 bar intervals at the beginning or middle of trends. But they also tend to occur at tops/bottoms, which makes their interpretation problematic. Another pattern that you will see quite frequently is a final strong bar in the direction of the trend, followed a few bars later by another strong bar in the reverse direction. My summary analyses seemed to indicate these were perhaps good points where one could make a bet on an early, risky reversal entry.
The last piece of information displayed by the indicator is the color of the candle bodies. Three possible colors are used. Bull/bear is determined by the polarity of DV, but only when the bar's polarity matches that of DV. When it doesn't, the color is the divergence color (orange, by default). Whichever color is used for the body, its intensity is determined by the DV% value. Maximum intensity occurs when DV%=100, so the more significant DV% values generate more noticeable colors. Body colors can be useful when looking to confirm the convergence of other components. The visual effect this creates hopefully makes it easier to detect patterns on the chart.
One obvious methodology that comes to mind to trade with this tool would be to use another indicator like Technical Ratings at a higher timeframe to identify the larger context's trend, and then use this tool to identify entries for short-term trades in that direction.
█ NOTES AND RAMBLINGS
Instant Calculations
This indicator uses instant values calculated on the bar only. No moving averages or calculations involving historical periods are used. The only exception to this rule is in some of the marker conditions like "Two consecutive DV+ values", where information from the previous bar is used.
Trading Small vs Long Timeframes
I never trade discretionary at the 5sec–5min timeframes this indicator was designed to be used with; I trade discretionary at 1D, 1W and 1M timeframes, and let systems trade at smaller timeframes. The higher the timeframe you trade at, the fewer fees you will pay because you trade less and are not churning trading volume, as is inevitable at smaller timeframes. Trading at higher timeframes is also a good way to gain an instant edge on most of the trading crowd that has its nose to the ground and often tends to forget the big picture. It also makes for a much less demanding trading practice, where you have lots of time to research and build your long-term opinions on potential future outcomes. While the future is always uncertain, I believe trades riding on long-term trends have stronger underlying support from the reality outside markets.
To traders who will ask why I publish an indicator designed for small timeframes, let me say that my main purpose here is to showcase what can be done with Pine. I often see comments by coders who are obviously not aware of what Pine is capable of in 2021. Since its humble beginnings seven years ago, Pine has grown and become a serious programming language. TradingView's growing popularity and its ongoing commitment to keep Pine accessible to newcomers to programming is gradually making Pine more and more of a standard in indicator and strategy programming. The technical barriers to entry for traders interested in owning their trading practice by developing their personal tools to trade have never been so low. I am also publishing this script because I value volume delta information, and I present here what I think is an original way of analyzing it.
Performance
The script puts a heavy load on the Pine runtime and the charting engine. After running the script for a while, you will often notice your chart becoming less responsive, and your chart tab can take longer to activate when you go back to it after using other tabs. That is the reason I encourage you to set the number of historical values displayed on bars to the minimum that meets your needs. When your chart becomes less responsive because the script has been running on it for many hours, refreshing the browser tab will restart everything and bring the chart's speed back up. You will then lose the information displayed on elapsed bars.
Neutral Volume
This script represents a departure from the way I have previously calculated volume delta in my scripts. I used the notion of "neutral volume" when inspecting intrabar timeframes, for bars where price did not move. No longer. While this had little impact when using intrabar inspection because the minimum usable timeframe was 1min (where bars with zero movement are relatively infrequent), a more precise way was required to handle realtime updates, where multiple consecutive prices often have the same value. This will usually happen whenever orders are unable to move across the bid/ask levels, either because of slow action or because a large-volume bid/ask level is taking time to breach. In either case, the proper way to calculate the polarity of volume delta for those updates is to use the last known polarity, which is how I calculate now.
The Order Book
Without access to the order book's levels (the depth of market), we are limited to analyzing transactions that come in the TradingView feed for the chart. That does not mean the volume delta information calculated this way is irrelevant; on the contrary, much of the information calculated here is not available in trading consoles supplied by exchanges/brokers. Yet it's important to realize that without access to the order book, you are forfeiting the valuable information that can be gleaned from it. The order book's levels are always in movement, of course, and some of the information they contain is mere posturing, i.e., attempts to influence the behavior of other players in the market by traders/systems who will often remove their orders when price comes near their order levels. Nonetheless, the order book is an essential tool for serious traders operating at intraday timeframes. It can be used to time entries/exits, to explain the causes of particular price movements, to determine optimal stop levels, to get to know the traders/systems you are betting against (they tend to exhibit behavioral patterns only recognizable through the order book), etc. This tool in no way makes the order book less useful; I encourage all intraday traders to become familiar with it and avoid trading without one.
