Updated with ATR based BUY/SELL signal with trailing SL lines.
1- Once BUY signal generated and below the candle is green square then it is perfect long entry with target as RED line price or any of the channel bottom price. (if RED line is close then use trailing SL GREEN line crossing the price as target) SL will be always the GREEN line price.
2- Once SELL signal generated and below the candle is red square then it is perfect short entry with target as GREEN line price or any of the channel top price. (if GREEN line is close then use trailing SL RED line crossing the price as target) SL will be always the RED line price.
NOTE - DO not enter if below the candle square color is opposite.
