Ehlers Decycler OscillatorThis indicator was originally developed by John F. Ehlers (Stocks & Commodities , V.33:10 (September, 2015): "Decyclers"). The idea is still the same as for the Simple Decycler. Mr. Ehlers suggested to virtually eliminate lag by getting rid of the very low-frequency components. So, he applied the high-pass filter to the simple decycler. Mr. Ehlers recommended to use two instances of the Decycler Oscillator with different parameters (high-pass filter period and multiplier). As a result, he got the Decycler Oscillator pair. The first oscillator (red line) has a period of 125 bars, the second one (yellow line) has a period of 100 bars. The interpretation is straightforward: When the yellow line crosses over the red line, a trend reversal to the upside is indicated. When the yellow line crosses under the red line, a trend reversal to the downside is indicated.

MTA-Traling StopIntroduction Based on my previous indicator , this indicator plot a trailing stop using classic conditions. Using The Indicator Like any trailing stop when price is higher than the trailing stop this imply a buy signals, when price is lower than the trailing stop this imply a sell signal. It is possible to use decimals instead of integers for length as shown here : length = 14.7 The indicator tend to react faster to price movements when a trend has been really long, this methodology is similar to the one used by the parabolic sar. Downsides Lack of robustness with the length parameter, the behaviour of the trailing stop can be hard to predict. There is a real need for control. Conclusion The indicator can be adaptive, even if it already is in a certain way, by changing the alpha variable at the start considering that 0 < alpha < 1. Its not recommended to use it right now except for testing/coding purpose. It is clear that i'm not enthusiast when it come to this script, there is a real lack of accuracy, i still hope it can be of use.

Motion To Attraction ChannelsIntroduction Channels are used a lot on technical-analysis, however most of the them rely on adding/subtracting a volatility indicator to a central tendency indicator, sometimes the central tendency indicator can even be replaced by pure price. A great channel who does not rely on this kind of architecture is the Donchian channels or the quartiles bands. Here i propose a channel similar to the one made by Richard Donchian with some additional abilities. The Channels In my indicator, Motion To Attraction mean that the movement of an object a attract an object b , but we can resume this approach by saying that the longer a trend period is, the smaller the distance between each channels, for example if the price create a new highest then the lowest will move toward this new highest, each time coming closer. The philosophy behind this is that the longer a trend is the more probable it is that she will end. The code reflect it this way : here the parameter controlling the channel A (upper) c = change(b) ? nz(c ) + alpha : change(a) ? 0 : nz(c ) this is traduced by : if channel b move then the parameter c become greater, if channel a move then reset the parameter , the parameter d do the same. c is used to move the channel A, when c < 1 A is closer to the highest, when c = 1 A is in a central tendency point, when c > 1 A is closer to the lowest. Slaving the Movement It is possible to have a better control over the channels, this is done by making c and d always equal or lower than 1. Of course it could be another max value selected by the user. In order to do that add c1 and d1 as parameter with c1 = c > 1 ? 1 : c , same with d1 but replace c by d. Its safer to do this but i prefer how the channels act the other way, i will consider implementing this option in the future. Conclusion This channel indicator does not rely on past data thanks to recursion. The alpha variable at the start can also be adaptive, this let you make the channels adaptive even if such idea can add non desired results. Low length values can create effects where the lower channel can be greater than the higher one, this can be fixed directly in the code or using the method highlighted in the Slaving the Movement part.

The 6 Line Death PunchIf you are looking to discover what trend you are in, you need to first what direction the price is going in... I've been using and testing a mixture of EMA's and SMA's for a long time and I've found that these ones are by far the best. EMA 3 EMA 8 MA 20 EMA 55 MA 100 MA 200 EMA 3 & 8 Crossover is a good method for confirming a coin going to the upside or to the downside. EMA 8 is known as the Trigger Line (trademarked brand) as one of the fib numbers it shows good support or resistance of a trend. MA 20 universal way of seeing trend direction in the stock market, works well with crypto too. EMA 55, another trusty fib number. Works very well and could trade off that alone as support and resistance. MA 100 and MA 200. Long ranged moving averages which govern the overall longer-term trend. LONG ENTRY Option 1 - 3/8 crossover Option 2 - Candles above EMA 8 Option 3 - Candles above MA 20 Option 4 - Candles Above EMA 55. SHORT ENTRY Option 1 - 3/8 crossover Option 2 - Candles below EMA 8 Option 3 - Candles below MA 20 Option 4 - Candles below EMA 55.

Adaptive Bandpass Filter [Ehlers]This is my latest bandpass filter - used to determine if a security is in a trend or cycle. Now with an adaptive period setting! I use Ehlers in-phase & quadrature dominant cycle measurement (IQ IFM) method to set the period dynamically. This method favors longer periods which tend to produce smoother, albeit laggier bandpass oscillator plots. From my quick tests, I tend to have lag between 4 and 8 bars, depending on the Timeframe. The lower timeframes tend to have more noise and thus produce more interfering frequencies that may cause lag. >Settings Source: Select the data source to perform calc's on (close, open, etc...) Period: Select the period to tune. Periods outside of this value will be attenuated (reduced) Adaptive: Enable to have the I-Q IFM set the period for you (disables Period setting) Bandpass Tolerance: Allow periods that are plus/minus the chosen period to pass. Cycle Tolerance: Sensitivity of cycle mode. Lower values consider trends more frequent, higher values consider cycles more frequent. Bandpass tolerance example: for instance, if this setting is 0.1 (10%) and Period is set to 20, then waves with a period of 18 - 22 will pass. >How to read Red line is the bandpass output, showing a lagged version of the dominant cycle representing the Black lines are the upper and lower bounds for a cycle Green Background indicates an uptrend Red background indicates a downtrend

Efficient Auto LineMore Efficiency Based on the Auto-Line code, the Efficient Auto Line aim to provide a more controlled adaptivity of the indicator. The first indicator of this sort worked this way : when the absolute difference between the price and the indicator is higher than the previous indicator +/- A pips of amplitude, the indicator will display the closing price, else its anterior value. The second indicator (Auto-Line) was adaptive and used the standard deviation instead of a constant A . This indicator will run both methodology providing both a trend strength indicator (Efficiency Ratio) parameter and two constant parameter. Parameters The length parameter will control the period of the efficiency ratio, a high period return lower values of the efficiency ratio. Since its an indicator in a range of (0,1) we use it to make our indicator more adaptive in trending market, this is when we need our two constant parameters, the fast/slow parameter can be any amount of pips where fast < slow , when the price is trending (efficiency ratio close to 1) the indicator will use the fast parameter, if its ranging (efficiency ratio away from 1) the indicator will use the slow parameter, then it will work like the first methodology previously explained. So the fast parameter should be equal to a small movement of pips (0.0001 or 1 pip) and the slow parameter should be equal to a number of pips you wont expect to see in a ranging market. At this point it is good to test for both parameter and see which values work better (a more automatic process is in development) . Hope you like it !

Volume ImpactVolume Impact (The area) Average Volume (The thick line, xTrigger) Volume Impact = Volume Chance - Average Volume It provides very reliable buy sell signals. Buy(green) when increasing, sell(red) when decreasing. Volume Impact might drop before the actual price so it has an early warning potential. Before trend changes volume average diverges from the prices. It moves reverse to the prices. Also before trend changes, volume impact peaks diverges from price peaks. So you know a big drop is coming. Klinger Volume Oscillator inspired this indicator... This data is there but it is more difficult to interpret. In summary, you can foresee trend changes.

ADX +- DiThis Adx +-Di is just a complete version of what the ADX is supposed to signal. So you have: 15 (contraction), 20 (threshold), 30 (expansion), 40 (resistance) levels. Below 20 the price is not trending Above 30 the price is trending Below 15 price has been in contraction for too long Between 20 and 30 price is in a "transition zone". I finally added a "Resistance" level (40), which has to be adapted to best represent the historical levels where price usually encounters resistance, and where the price can be declared "overtrending", which means a return to lower levels is likely to happen. I've chosen mild colors, and set the Adx Color to White, because I use black background, you can easily change that. Enjoy -Maurice

CryptoCoyns MACDS [v2018-12-10]CryptoCoyns MACDS This indicator implements a standard Moving Average Convergance / Divergance that works on any chart timeframe. It shows the strength of the current trend. MACD Crosses are highlighted with yellow circles to make them more obvious. Strength is indicated by histogram colours moving from Red (weak) through to Light Green (strong): Red indicates a strong down trend Yellow indicates a positive change is coming and moving out of a downtrend. Green indicates a weakening upward trend moving towards a change to a downward trend. Light Green indicates a strong upward trend All colours are fully configurable.

Repulsion Moving Average - Least Crosses MAA Moving Average With Less Whipsaws Signals The cross of the price with a moving average is one of the easiest strategy in technical analysis and could have worked if market price wasn't so noisy (In general periods of 1 to 20 produces the most whipsaws) . So it is possible to create a moving average who can manage to escape those noisy periods and produce 0 whipsaws ? This question was asked by one of my work colleagues and i responded : "well... almost 0". The Motion Of A Moving Average Moving Average estimate the Trend and will always have phase shift, they will still follow the price and cross it during high volatility or low volatility periods, and when a moving average cross the price during a low volatility period you can expect lot of crosses. In order to fix this behaviour a simple calculation exist : FixMa = LongPeriodMA + MediumPeriodMA - ShortPeriodMA We can see things in that way, the medium term MA is high pass filtered (subtracted) with a short term MA and the result is summed to a long term MA. We give more reactivity to our long term MA and thus creating some kind of repulsion motion with the price. Of course this can sometimes make the filter kinda zero-lag to some price periods (when the long term MA is near the price) . Comparison In red a simple moving average of period 100 and in blue our repulsion moving average : In the image the short term moving average period is 100, since the long term period of the moving average is equal to short term x 3 you could be interested to look at the comparison of our moving average with the actual long term moving average : Less crosses, i think you can see it. Something to notice is that its always a tradeoff between Signal Speed and Signal Numbers , a classic moving average create faster signals but also a high numbers of them, a classic trailing stop create less signals but slowest ones, our moving average is some kind of average between those indicators. Improvement Methods - Choice of The Filter/More Terms A bad behaviour of our filter can be fixed by using filters who tend to create less crosses with the price or by developing the formula of our filter by adding more terms as follow : fixma = ma(Price,a) + ma(Price,b) + ma(Price,c) - ma(Price,d) - ma(Price,e) where a > b > c > d > e . The number of subtractive terms is equal to the number of summing terms - 1. Way To Use This indicator can be used like any moving average with cross strategy. Can also be used as a trailing stop. No tests have been made proving that this indicator provide support and resistance levels, such signals come from more centered indicators. Hope you enjoy For any questions/demands feel free to pm me, i would be happy to help you :)
