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. Thanks for reading !

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.

BEST ABCD Pattern ScreenerHello ladies and gentlemen traders Continuing deeper and stronger with the screeners' educational series one more time. This one is heavy crazy mega cool (pardon my french). I - Concept I present to you, ladies and gentlemen, the first screener for harmonic patterns. Starting with an ACBD pattern screener this time!! I used the calculations from Ricardo Santo's script In short, he's using fractals (regular or Bill Williams ) for the pattern calculations. A masterpiece !!! The screener will show in 1 consolidated chart the ABCD patterns for 5 selected assets. Could be stocks, forex, crypto, whatever you feel like making money with II - Definitions The ABCD pattern ( AB=CD ) is one of the classic chart patterns which is repeated over and over again. The ABCD pattern shows perfect harmony between price and time. More info here The Williams Fractal is an indicator, developed by Bill Williams, that aims to detect reversal points (highs and lows) and marks them with arrows. Up fractals and down fractals have specific shapes. The Williams Fractal indicator helps users determine in which direction price will develop Source: www.pulsewire.com III - How did I set the screener The visual signals are as follow: - square: whenever there is an ABCD pattern detected Then the colors are: - green when a bullish pattern is detected - red when a bearish pattern is detected 🔸 The script screenshot shows two red squares matching two ABCD bearish pattern from the above panel. As the chart is showing APPL, I highlighted where the screener mentioned the fruit stock ( APPLE, pun, bad joke, Dave out...) 🔸 I tried to make it as clear as I could with red arrows Once again, we pushed together the limits of pine script beyond of what we thought was possible, beyond the realm of this world, reaching finally the dreamt pine script heaven (am I going too far? feel free to tell me) Best regards, Dave

Doji strategyThis is a simple strategy based on Doji star candlestick. It places two orders: buy stop at doji star high or previous candle high and sell stop at doji star low or previous candle low. Exit rules are with take profit and fixed stop loss or take profit and stop loss at doji min or max. This strategy works very well with high time frames like Daily and Weekly because those are without noise in doji formation. Each currency pair has its own optimal setting for TP and SL: it's up to user find the best ones. I could implement SL based on ATR, maybe in next revision. Please use comment section for any feedback. Next improvement (only to whom is interested to this script and follows me): study with alerts on multiple tickers all at one. Leave a comment if you want to have access to study.

Bullish/Bearish Candelstick patternHey! This time I took the pattern recognizer from a previous script I worked. It overlays the Arrows on the chart. Legend: #Maroon colour: Strong bearish signal #Red colour: Bearish signal #Dark Green colour: Strong bullish signal #Lime: Bullish signal NOTE: Also, you can untick the patterns you don't find useful, but I kept every pattern to get a complete script. I unticked: Morning Star Evening Star Shooting Star Bullish Harami (too bearish on corrective phase) Hanging Man Red Cloud Cover

Fractal Breakout V2Version 2 of my fractal pattern aid ( Version 1 ). I added a bouncing line between the high and low trend lines, connecting consecutive extreme points. I also chased down a pesky bug in the slope calculation...and for now I have disabled the ability to change resolution basis for extreme detection (e.g. 30m on a 1hr chart). For fun, I added some shading to make it more apparent at a glance what is happening, but if you find it gimmicky, there's an option to turn that off. I am inexperienced with pattern recognition, so please send feedback if you have any ideas that would make this more useful. Thanks! Lemrin

PorcupineDisplays "spike days" by colouring the bars (Default: yellow for a Spike High and blue for a Spike Low) Spike Day's definition taken from Jack D Schwager's Book: A Complete Guide to the Futures Market: Technical Analysis, Trading Systems, Fundamental Analysis, Options, Spreads, and Trading Principles A spike is: A wide difference between the spike high and the highs of the preceding and succeeding days. A close near the low of the day's range. A substantial price advance preceding the spike's formation. The more extreme each of these conditions, the greater the likelihood that a spike high will prove to be an important relative high or even a major top. (inverse is true for lows, basically) Enjoy!

3-Bar-Reversal-Pattern Strategy This startegy based on 3-day pattern reversal described in "Are Three-Bar Patterns Reliable For Stocks" article by Thomas Bulkowski, presented in January,2000 issue of Stocks&Commodities magazine. That pattern conforms to the following rules: - It uses daily prices, not intraday or weekly prices; - The middle day of the three-day pattern has the lowest low of the three days, with no ties allowed; - The last day must have a close above the prior day's high, with no ties allowed; - Each day must have a nonzero trading range.
