okay... okay ... i will share what i can do and how i trade with this 3rd candle ...
in order to master this you have to really identify the reversal candle or Japanese candlestick reversal ...
like hammer, hanging man, inverted hammer, shooting star, bearish and bullish engulfing candle so there more but this is the one that i normally try to spot first.
so this you have to practice your self on how to identify this candle as this candle formation is plenty especially with M15 time frame.
so this form the formation of 1 2 3 candle
1 is the reversal candle
2 is candle closed align with the reversal candle meaning current trend is long then the reversal candle is formed then this 2n candle close in short trend.
3 is where u open your position at the 3rd candle. stop loss and take profit sets.
