I have two strategys with same conditions and both start wait until flat.
The 1 strategy in SPY work good all day
The 2 strategy in ES with conditions SPY not work fine, some times no entry the orders or entry one bar late.
The 2 strategy when fail and not entry, i uncheck and check again int he control center and the position change and write the correct price of entry in past.
For some reason not entry in the correct moment.
