The Double Trouble Pattern Recognition in TradingView
Coding a Double Trouble 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 Double Trouble 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 Double Trouble 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 Double Trouble pattern is a two-candlestick trend following configuration. The general shape is a candlestick relatively bigger than the previous one. The size metric is measured using a volatility metric called the average true range (ATR).
The bullish Double Trouble is composed of a bullish candlestick with a body range greater than the 10-period ATR of the previous bullish candlestick. The following Figure shows a theoretical illustration of the bullish Double Trouble.
The bearish Double Trouble is composed of a bearish candlestick with a body range greater than the 10-period ATR of the previous bearish candlestick. The following Figure shows a theoretical illustration of the bearish Double Trouble.
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 Double Trouble patterns using the following indications:
A green arrow for bullish Double Trouble signals.
A red arrow for bearish Double Trouble signals.
