EA opens new trades even when one is already running

[Wangui89]

Hello! I’m building an EA where entries can be triggered by either a trend filter cross or an EMA cross.

It should open only one trade (or trade set) open at a time.
If a buy trade is active from one condition, no other condition (trend filter or EMA cross) should open a new one until that trade fully closes.

My current issue:
Even with “No position” or “Check positions count == 0” blocks placed before both entry paths, the EA sometimes still opens a new trade when another is already running. It doesn’t matter if it came from the other signal logic (trend or EMA).

Could someone please look at my structure so I can solve this issue, Ty! Here is the link:https://fxdreema.com/shared/HHCSf5j0b

You need to use a 'no position' block on top of each branch tree opening a trade so that as soon as any of them opens a trade no other branch will.

I have added the no position block, its working perfectly at first then mid backtest its opening 4 positions at once, from the same entry logic, what could i be missing? I have tried adding once per bar too but its not fixing it. Here is the link; https://fxdreema.com/shared/AFpEB4rGd

once per bar should be on top after time filter block

@Wangui89 No, this is not where I said. Those 'once per bar' blocks need to be position here:
