Pine Script V5 - Not getting expected breakout entry price and entry in expected bar - pine-script-v5

Question

I have a long entry buy condition where
Candle time frame is 15 minutes
Alert candle high is below lower band of bollinger bands.
entry when next candle crossover the alert candle high
This script gives entry oh high breakout + 0.01 but it does not give entry in the exact breakout candle and gives entry when price comes next time on expected entry price i.e. alert candle high + 0.01.
Requesting solution to get entry in breakout candle itself and at expected breakout price.
