This Expert Advisor is rewritten from MQL4 and was originally published here https://www.mql5.com/en/code/8146 by its author Reshetov.  

How It Works

The direction for an entry is determined by the SAR indicator, provided that ADX is lower than the level specified. If the last trade was winning, a position can be opened in the direction of the last winning trade. If the last trade was losing, a position can be opened only in the direction opposite to that of the last trade.
