Fast Z-ScoreIntroduction The ability of the least squares moving average to provide a great low lag filter is something i always liked, however the least squares moving average can have other uses, one of them is using it with the z-score to provide a fast smoothing oscillator. The Indicator The indicator aim to provide fast and smooth results. length control the smoothness. The calculation is inspired from my sample correlation coefficient estimation described here Instead of using the difference between a moving average of period length/2 and a moving average of period length , we use the difference between a lsma of period length/2 and a lsma of period length , this difference is then divided by the standard deviation. All those calculations use the price smoothed by a moving average as source. The yellow version don't divide the difference by a standard deviation, you can that it is less reactive. Both version have length = 200 Conclusion I presented a smooth and responsive version of a z-score, the result could be used to estimate an even faster lsma by using the line rescaling technique and our indicator as correlation coefficient. Hope you like it, feel free to modify it and share your results ! :) Notes I have been requested a lot of indicators lately, from mt4 translations to more complex time series analysis methods, this accumulation of work made that it is impossible for me to publish those within a short period of time, also some are really complex. I apologize in advance for the inconvenience, i will try to do my best !

Absolute Strength MTF IndicatorIntroduction The non-signal version of the absolute strength indicator from fxcodebase.com requested by ernie76 . This indicator originally from mt4 aim to estimate the bullish/bearish force of the market by using various methods. The Indicator Two lines are plotted, a bull line (blue) representing the bullish/buying force and a bear one (red) representing the bearish/selling force, when the bull line is greater than the bear line the market is considered to be strongly bullish, else strongly bearish. The indicator use various method, Rsi, stochastic, adx. The Rsi method is the one by default. The stochastic method is less reactive but smoother The Adx method is way different, while the other two methods make the bull and bear lines somewhat uncorrelated, the adx method focus more on the overall market strength than individual buyer/seller strength. The smoothing method use 3 different filters, SMA, EMA and LSMA, LSMA is more reactive than the two previous one while EMA is just more computer efficient. It is possible to use price data of different time frames for the calculation of the indicator. Stochastic method with 4 hour price close as source. Conclusion A classic indicator who can be derived into a lot of ways using a more adaptive architecture or recursion. Hope you find it a use :) A big thanks to ernie76 for the request and the support/testing of the indicator Feel free to pm me for any request.

Modified Gann HiLo ActivatorIntroduction The gann hilo activator is a trend indicator developed by Robert Krausz published into W. D. Gann Treasure Discovered: Simple Trading Plans for Stocks & Commodities . This indicator crate a trailing stop aiming to show the direction of the trend. This indicator is fairly easy to compute and dont require lot of skills to understand. First we calculate the simple moving average of both price high and price low, when the close price is higher than the moving average of the price high the indicator return the moving average of the price low, else the indicator return the moving average of the price high if the close price is lower than the moving average of the price low. My indicator add a different calculation method in order to avoid whipsaw trades as well as adding significance to the moving average length. A Median method has been added to provide more robustness. The Indicator The indicator is a simple trailing stop aiming to show the direction of the trend. The indicator use a different source instead of the price high/low for its calculation. The first method is the "SMA" method which like the classic hilo indicator use a simple moving average for the calculation of the indicator. Sma Method with length = 25 The "Median" use a moving median instead of a simple moving average, this provide more robustness. Median Method with length = 25 The shape is less curved and the indicator can sometimes avoid whipsaw with high's length periods. Mult Parameter The mult parameter is a parameter set to be lower or equal to 1 and greater or equal to 0. High values allow the indicator to be far from the price thus avoiding whipsaw trades, lower ones lower the distance from the price. A mult parameter of 0.1 approximate the original hilo indicator. In blue the indicator with mult = 0.1 and in radical red the original hilo activator. Conclusion The modifications allow more control over the indicator as well as adding more robustness while the original one is destined to fail when market price is more complex. Thanks for reading :) For any questions/suggestions feel free to pm me

Flagging BandsIntroduction A pun between the word flag and the adjective flagging (less dynamic) , this indicator have two bands who react faster when in contact to the price. Imagine you are under sheets, if you abruptly rise, the sheets will instantaneously go up, then if you abruptly get down, the sheets will fall slowly until being in contact with a surface, this is because of a type of friction called drag or air resistance , this force is described in fluid dynamics and i inspired myself from that for the creation of the indicator. The indicator The indicator is made of two bands, one upper band and one lower band, then a weighted average of each bands, this average is weighted depending on which band the price is closer. The length control the period of the indicator, in general higher lengths will create wider bands, you must consider that this parameter behave differently than other ones and may create slower results in comparison with other bands indicators while having the same length period. The indicator can use a simple breakout methodology (see trailing stop part) but can sometime provide support and resistance points, in fact i believe that when the average variability/volatility of band A is higher than the average variability/volatility of band B and that the price cross band B then price will reverse its direction, this claim is not justified, research is needed. Trailing Stop Mod It is possible to make the indicator act as a trailing stop, in order to do so just tick the trailing stop mod box. The average/bands will automatically disappear being replaced by the trailing stop. Conclusion I was just playing around when making the skeleton of the indicator, i hope the code is easy to understand, if you need some kind of explanation just pm me, i'm always open to help people/receive suggestions. Best Regards

Surface Roughness EstimatorIntroduction Roughness of a signal is often non desired since smooth signals are easier to analyse, its logical to say that anything interacting with rough price is subject to decrease in accuracy/efficiency and can induce non desired effects such as whipsaws. Being able to measure it can give useful information and potentially avoid errors in an analysis. It is said that roughness appear when a signal have high-frequencies (short wavelengths) components with considerable amplitudes, so its not wrong to say that "estimating roughness" can be derived into "estimating complexity". Measuring Roughness There are a lot of way to estimate roughness in a signal, the most well know method being the estimation of fractal dimensions. Here i will use a first order autocorrelation function. Auto-correlation is defined by the linear relationship between a signal and a delayed version of itself, for exemple if the price goes on the same direction than the price i bars back then the auto-correlation will increase, else decrease. So what this have to do with roughness ? Well when the auto-correlation decrease it means that the dominant frequency is high, and therefore that the signal is rough. Interpretation Of The Indicator When the indicator is high it means that price is rough, when its low it indicate that price is smooth. Originally its the inverse way but i found that it was more convenient to do it this way. We can interpret low values of the indicator as a trending market but its not totally true, for example high values dont always indicate that the market is ranging. Here the comparison with the indicator applied to price (orange) and a moving average (purple) The average measurement applied to a moving average is way lower than the one using the price, this is because a moving average is smoother than price. Its also interesting to see that some trend strength estimator like efficiency ratio can treat huge volatility signals as trend as shown below. Here the efficiency ratio treat this volatile movement as a trending market, our indicator instead indicate that this movement is rough, such indication can avoid situation where price is followed by another huge volatile movement in the opposite direction. Its important to make the distinction between volatility and trend strength, the trend is defined by low frequencies components of a signal, therefore measuring trend strength can be resumed as measuring the amplitude of such frequencies, but roughness estimation can do a great job as well. Conclusion I have showed how to estimate roughness in price and compared how our indicator behaved in comparison with a classic trend strength measurement tool. Filters or any other indicator can be way more efficient if they know how to filter according to a situation, more commonly smoothing more when price is rough and smoothing less when price is smooth. Its good to have a wider view of how market is behaving and not sticking with the binary view of "Trending" and "Ranging" . I hope you find a use to this script :) Best Regards

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.
