Overview

The Bearish Harami Reversal Backtest Strategy identifies bearish Harami reversal patterns in candlestick charts and automatically trades them. It goes short when detecting a bearish Harami pattern and closes the position when the stop loss or take profit is triggered.

Strategy Logic

The core pattern recognition indicator of this strategy is: the close of the first candle is a long bullish candle and the second candle's close is inside the first candle's body, forming a bearish candle. This indicates a potential Bearish Harami reversal pattern. When this pattern forms, the strategy goes short.

The specific logic is:

1. Calculate if the body size of the first candle ABS(Close1 - Open1) is greater than the set minimum body size
2. Check if the first candle is bullish Close1 > Open1
3. Check if the current candle is bearish Open > Close
4. Check if current candle's open is less than or equal to previous close Open <= Close1
5. Check if previous candle's open is less than or equal to current candle's close Open1 <= Close
6. Check if current candle's body is less than previous body Open - Close < Close1 - Open1
7. If all conditions pass, a Bearish Harami has formed and the strategy goes short.
