1 Price has to close lower than previous high candle (but still be within the previous candle).
2. After candle close, place a short and let it run to your target tp.
Buy Setup:
1 Price has to close higher than previous low candle (but still be within the previous candle).
2. After candle close, place a long and let it run to your target tp.
