FunctionDynamicTimeWarpingLibrary "FunctionDynamicTimeWarping" "In time series analysis, dynamic time warping (DTW) is an algorithm for measuring similarity between two temporal sequences, which may vary in speed. For instance, similarities in walking could be detected using DTW, even if one person was walking faster than the other, or if there were accelerations and decelerations during the course of an observation. DTW has been applied to temporal sequences of video, audio, and graphics data — indeed, any data that can be turned into a linear sequence can be analyzed with DTW. A well-known application has been automatic speech recognition, to cope with different speaking speeds. Other applications include speaker recognition and online signature recognition. It can also be used in partial shape matching applications." "Dynamic time warping is used in finance and econometrics to assess the quality of the prediction versus real-world data." ~~ wikipedia reference: en.wikipedia.org towardsdatascience.com github.com cost_matrix(a, b, w)   Dynamic Time Warping procedure.   Parameters:      a : array, data series.      b : array, data series.      w : int , minimum window size.   Returns: matrix optimum match matrix. traceback(M)   perform a backtrace on the cost matrix and retrieve optimal paths and cost between arrays.   Parameters:      M : matrix, cost matrix.   Returns: tuple: array aligned 1st array of indices. array aligned 2nd array of indices. float final cost. reference: github.com report(a, b, w)   report ordered arrays, cost and cost matrix.   Parameters:      a : array, data series.      b : array, data series.      w : int , minimum window size.   Returns: string report.

Fake breakHi Traders, I've developed an indicator which can detect fake-breaks on the chart. In the following you'll find the definition of the fake break candles and also you will find how to recognize it on the chart with practical examples. What is the fake break pattern? Sometimes support and resistance lines broke with a full body and strong candles that gives us the idea of sharp movements on the chart but suddenly the next candle returns all the path of the previous candle. in this case we can say fake break is happening on the chart. This indicator detect fake break patterns based on two criteria: 1. It uses AverageTrueRange indicator to measure the strength of the pattern. 2. The returning candle should engulf minimum 75% of the break candle. This indicator plot 2 terms in the name of "FB-D" and "FB-U" that are abbreviations of the "Fake Break Down" and "Fake Break Up". You can also set alerts to get notified when fake breakout happens on the chart. Notice: This pattern is only acceptable in valid support and resistance zones and you can not rely on it everywhere on the chart (specially in the middle of the waves). Notice: The source code of this indicator is open and you are allowed to use it on your scripts by mentioning the name of author. Disclaimer: This is not a financial advice or any signal to buy or sell, the goal of developing such an indicator is to use for educational purposes.

VWAP/EMA50/EMA200We script this one for combining VWAP , EMA50 and EMA200. The tool is fantastic if traders know how VWAP , EMA work? Just adding this script in your favorite and work like charm: VWAP: How to trade with that - One of the simplest uses of the VWAP is gauging support and/or resistance. - A trader who is long a stock can use the VWAP as a target exit if its trading below. - A stock trading over intraday VWAP may be bullish , while a stock trading under may be bearish . EMA 50/EMA200: How to trade with that timeframe 50-day or 200-day period - Identify the trend of market in longterm - Golden-cross (short term EMA cross above longterm EMA ) is call golden-cross signals. It is opportunity for buying. - Deal-cross ( short term EMA cross below longterm EMA ) is call dead-cross signals. It is opportunity for selling. - Identify support levels - Identify resistance levels Let me know if you see anything else that should be added/changed.

Fibonacci Timing PatternThe Fibonacci Timing Pattern is a price-based counter that seeks to determine short-term and medium-term reversals in price action. It is based on the following set of conditions: * For a bullish Fibonacci timing signal: The market must shape 8 consecutive close prices where each close price is lower than the close prices from 3 and 5 periods ago. * For a bearish Fibonacci timing signal: The market must shape 8 consecutive close prices where each close price is higher than the close prices from 3 and 5 periods ago. The signals of the pattern are ideally used in a sideways market or used in tandem with the trend (bullish signals are taken in a bullish market and bearish signals are taken in a bearish market).

K's Reversal Indicator IK's reversal indicator I is a special combination between Bollinger bands and the MACD oscillator. It is a contrarian indicator that depends on the following conditions: • A buy signal is generated whenever the current market price is below the 100-period lower Bollinger band while simultaneously, the MACD value must be above its signal line. At the same time, the previous MACD value must be below its previous signal line. • A sell (short) signal is generated whenever the current market price is above the 100-period upper Bollinger band while simultaneously, the MACD value must be below its signal line. At the same time, the previous MACD value must be above its previous signal line. The way to use K's reversal indicator is to combine it with your already long/short bias in a sideways/range market in order to maximize the probability of success. Limitations of the indicator include the following: • There are no clear exit rules that work well on average across the markets. Even though K’s reversal indicator gives contrarian signals, it does not show when to exit the positions. • As with other indicators, it underperforms on some markets and is not to be used everywhere. • False signals tend to occur during trending markets but there is no proven way to detect a false signal.

Candilator RSI [AstrideUnicorn]OVERVIEW The name Candilator comes from blending the words "candlestick" and "oscillator". And as the name suggests, this indicator is a good old RSI plotted as a candlestick chart. To produce a candlestick chart, Candilator RSI calculates four RSI's based on the open, high, low, and close time series. It also has a candlestick patterns detection feature. HOW TO USE You can use Candilator RSI as a normal RSI to analyze momentum, detect overbought and oversold markets, and find the oscillator's divergences with the price. You can also get creative and apply all sorts of technical analysis to the RSI candlestick chart, including candlestick patterns analysis. Candilator RSI can automatically scan the price for some candlestick patterns in the overbought and oversold zones. This feature can help detect price reversals early. SETTINGS The indicator settings are divided into two groups: Main Settings and Pattern Detection. In the Main Settings, you can find standard RSI settings. In the Pattern Detection part, you can turn on and off the automatic search for a particular candlestick pattern.

Manual Backtest - Flat the ChartThis script is an utility tool for manual backtesting. The main problem in backtesting a discretionary strategy is the bias of knowing the future result of the market, in this way all the market will be crushed into a flat line, this way you can avoid bias. The way to use this indicator is easy and made by 4 step: Step 1 : add to an asset you won't backtest and put the auto scale on Step 2 : go to the asset you will backtest and scroll left until the date you want to start Step 3 : use the replay function of pulsewire (15 min chart won't go back more than 18 month) Step 4: toggle off the indicator or remove from the chart (untill next asset to backtest) That's not a complex indicator but is what you need to do a fair backtesting

Doji Hunter█ OVERVIEW This script is built to search for 8 different Doji candlestick patterns in markets and makes them appear on screen with bar coloring and creating color-coded labels/shapes. It will identify the following variants based upon user input for various rules to abide by: Gapping Up Gapping Down Gravestone Dragonfly Long-Legged Rickshaw Man Northern (Doji in uptrend) Southern (Doji in downtrend) Note: for the remainder of this description, the types for inputs will be marked by italic text. █ OPTIONS This script features a wide range of options available to the user to modify how it functions. The first set of inputs dictate how the trend analysis is done with moving averages. The second and third sets of inputs dictate specific rules for how Doji candles are analyzed and the colors used for when they appear. █ INPUTS (short) 1 — Moving Average Rules: The Northern and Southern Doji variants require some trend analysis which will be done by Moving Averages. The inputs in this section change various things about the moving average(s) to be used. In the second section of inputs, there is one boolean option that will nullify the need for trend detection and consolidates the Northern and Southern Doji variants into one. 2/3 — Doji Rules and Colors: The next two sections of inputs correspond to the various rules that dictate how various doji variants will be analyzed, as well as the colors that correspond to each variant. The colors will also apply to each of the labels/shapes used. 4 — Diagnostics: The last boolean will allow the user to see extra detail with regards to how and when dojis are detected. Note: This is not a part of any prior section and is simply included as a last functional item to the list of all inputs. An example of multiple labels being shown on screen for various types of Dojis (DJI 1D chart): █ INPUTS (extended) 1 — Moving Average Rules: This section consists of 10 different inputs specific to the rules on how the moving average functions for trend analysis. "Trend Rule" ( string list) determines which Moving Average will be used for trend detection. It has 3 options: "MA 1", "MA 2", or "BOTH". The second input "Trend Source" determines which OHLC (or combination) value to use in comparison to either MA 1 or MA 2 (EX: Trend Rule -> "MA 1" and Trend Source -> "close": if close > MA 1 -> uptrend, downtrend otherwise). If "BOTH" is selected then "Trend Source" is ignored and added nuance in the script ensures that the shorter MA being above the longer MA yields an uptrend (downtrend otherwise). The next 8 inputs focus on 4 different parts of both MA 1 and 2. Length ( integer(s) ) Color Switch between SMA/EMA ( boolean(s) ) Source for MA Note: Additional attention to detail has been made here as trend direction is ignored if "BOTH" is selected for the MA Rules and the lengths of both Moving Averages are set to be the same. 2/3 — Doji Rules and Colors: The next two sections include 19 inputs that are related to how this script will analyze and identify the different variants of Doji candles. "Identify Pattern On Close" ( boolean ) modifies which candles are to be used for determining when Doji candles are recognized. This changes an offset used for historical reference on some global variables which will force the script to only identify patterns after the current candle has closed. "Doji Body Tolerance" ( float ) tells the script the maximum % the candle body may be of the high-low range to be considered a Doji candle. "Doji Wick Sample" ( integer ) defines how many prior candles to sample from in calculating the current average upper and lower wick sizes. "Simplify Northern/Southern Dojis" ( boolean ) makes this script ignore trend direction for Doji detection and consolidates Northern and Southern Dojis into being recognized as the same. This has an added effect of removing the plotted moving averages from the screen. "Northern/Southern Display" ( string list ) that has multiple options for how Northern and Southern Dojis will be displayed on screen. Because of how labels may be extremely taxing on PulseWire's servers to display, the default setting is "shapes" where Northern and Southern (N/S) Dojis will be marked with a colored triangle at the top of the candle. If "Simplify Northern/Southern Dojis" is true, all N/S Dojis will be marked with an x-cross instead. Other options include "labels" which enables the use of labels accompanied by their respective tooltip and color, or "none" where N/S Dojis will be only noticeable by their changed barcolor. "Allow Gravestone/Dragonfly Shadows" ( boolean ) allows a bit of additional nuance to the definition of Gravestone or Dragonfly Dojis with small shadows. "Gravestone/Dragonfly Shadow Tolerance" ( float ) defines the maximum % that the lower wick/upper wick (respectively) may be relative to the high-low range for Gravestone or Dragonfly Dojis to still be considered valid. "Doji Long Wick Setting" ( string list) is a list of settings for three different ways of confirming if a Doji is Long-Legged. The settings are "one", "two", and "average". These define how many wick lengths of a candle need to exceed the calculated average wick lengths (EX: "both" -> upper wick length > upper wick average and lower wick length > lower wick average). The "average" setting will combine the lengths of both wicks and both prior wick averages, divide both of these sums by 2 and compare them instead. "Doji Long Wick Tolerance" ( float ) defines how large compared to the averages that wick lengths need to be in order for them to be considered "Long-Legged" (EX: 1.50 -> upper/lower wick needs to exceed 150% the average of previous upper/lower wicks). "Rickshaw Man Body Placement Tolerance" ( float ) defines how close to the high-low range's midpoint the candle body's midpoint needs to be in order for it to be considered a Rickshaw Man Doji candle instead. The remaining 9 inputs define the colors to use for differentiating between all Doji variants this script will recognize. █ USAGE My hope for this script is that users find this easy to use/understand and will tinker with the input values to better identify Doji candlesticks across a wide range of markets. Suggestions for changes in the future are welcome.

Swing Failure Pattern Inquisitor SFP Inquisitor v0.2a coded by Bogdan Vaida Code for Swing High, Swing Low and Swing Failure Pattern. Note that we're still in the alpha version, bugs may appear. Note that the number you set in your Swing History variable will also be the minimum delay you see until the apples appear. This is because we're checking the forward "history" too. The SFP will only check for these conditions: - high above Swing History high and close below it - low below Swing History high and close above it In some cases you may see an apple before the SFP that "doesn't fit" with the SFP conditions. That's because that apple was drawn later and the SFP actually appeared because of the previous apple . 20 candles later. Legend: 🍏 - swing high 🍎 - swing low 🧺 - candle where the last swing was driven from 🍌 - swing failure pattern 🍎🍌 - hungry scenario: swing low but also a SFP compared to the last swing

Candlestick Pattern IdentifierMy script builds upon another user-submitted script by rebuilding the logic used to identify candlestick patterns. The logic in my script is a mix of strict and lax guidelines to mitigate false flags and present valid buy and sell signals. -To use this indicator, simply add it to any chart. It will identify trends on any time frame although the lower you go, the more signals you'll see and the higher probability of those signals being false flags. You can also disable any candlestick patterns that you feel are not as useful. - This indicator works best with Stocks and also with Forex markets to a lesser extent. - This indicator works the best on the Daily chart and also works (with varying degrees of success) on any timeframe at or above 1 hour. I've found that this indicator works the best when used in tandem with the Daily and Hourly charts with the Hourly chart being used to determine an entry point while the Daily chart is used for long term trend analysis.

123 Trend Continuation PatternThis simple indicator will help identify the 123 Patterns on the charts. It's build based on the zigzag indicator, which will work as a guideline to identify the 3 points. As soon as the price crosses the third point, the indicator will draw 3 lines: entry, take profit, and stop loss. Those lines will work as a reference and may help with other indicators. This kind of analysis will work on any time frame and symbol, but those markets that have high volatility may have better result
