The Three Candles Pattern Recognition in TradingView
Coding a Three Candles Candlestick Pattern Scanner in TradingView
Candlestick patterns are a great addition to market analysis. Some may even consider them vital in research and trading. This article presents the Three Candles pattern and shows how to code a scanner in TradingView that detects it.
For the complete collection of candlestick patterns in detail with back-tests and technical strategies, you can check out my newest book with O’Reilly Media. The book features a huge number of classic and modern candlestick patterns as it dwelves into the realm of technical analysis with different trading strategies. The book comes with its own GitHub and is dynamic in nature as it is continuously updated and questions are answered on the O’Reilly platform promptly.

The Three Candles Pattern
Candlestick charts are among the most famous ways to analyze the time series visually. They contain more information than a simple line chart and have more visual interpretability than bar charts.
The Three Candles pattern is a trend following classic configuration where three successive candlesticks of the same color confirm the on-going trend. The particular detail of this pattern is that the bodies of the candlestick must be relatively big.
The bullish Three Candles (also known as Three White Soldiers) is composed of three big bullish candlesticks. The following Figure shows a theoretical illustration of the Three White Soldiers.
The bearish Three Candles (also known as Three Black Crows) is composed of three big bearish candlesticks. The following Figure shows a theoretical illustration of the Three Black Crows.
Coding the Scanner in TradingView
The conditions of the pattern are relatively easy to code especially in a straightforward and simple coding language such as Pine Script, TradingView’s native language.
The aim of the scanner is to detect the Three Candles patterns using the following indications:
A green arrow for the Three White Soldiers signals.
A red arrow for the Three Black Crows signals.

To sum up, what I am trying to do is to simply contribute to the world of objective technical analysis which is promoting more transparent techniques and strategies that need to be back-tested before being implemented. This way, technical analysis will get rid of the bad reputation of being subjective and scientifically unfounded.
I recommend you always follow the the below steps whenever you come across a trading technique or strategy:
Have a critical mindset and get rid of any emotions.
Back-test it using real life simulation and conditions.
If you find potential, try optimizing it and running a forward test.
Always include transaction costs and any slippage simulation in your tests.
Always include risk management and position sizing in your tests.
Finally, even after making sure of the above, stay careful and monitor the strategy because market dynamics may shift and make the strategy unprofitable.
