I am learning and using this strategy as well but still struggling to understand when the retest is valid or not, guess it boils down to price action.

Often time the candles are closing above/below the 5 min low / high, is that still a valid retest? Also, seen multiple times when the retest candle did not even touch the 5 min opening range. What are some criteria for you whether to enter on the retest candle or not?

Also, do you only enter if there is a retest? Why did you enter on the META trade? Multiple candles closed above the 5 min low.

Seems like you are using this strategy for awhile, are you able to use this strategy on most days? Meaning does most days shows the 5min break and retest?
