##Entry: If closing Price(n1) exceeds ALL the closing prices of the prior three candles (n-2),(n-3),(n-4) AND the HIGHS of the prior five candles,(n2),(n3),(n4)(n5) (n6) then Enter.
##Exit/close: If the  close price of ALL the prior three candle’s(n1),(n2) & (n3) exceed,(>) LIVE current price(n0),  AND current price(n0) is below lows of the prior 5 candles(n2)(n3)(n4)(n5)(n6).

Certainly! I've integrated the two code snippets into a combined version, making sure the functions work together. Note that I added some placeholders for `oEquity` and `strike` as they were not defined in the original code. Please replace them with the appropriate values when integrating with your complete program.
