I see that your EA looks like this:

But this is not the correct way of connecting the lower half of the blocks. Take a look at this: https://fxdreema.com/tutorial/builder/things-not-to-do#2
Basically, disconnect the lines between blocks 4 and 11, and between 10 and 14
Then it is very important to Not reach any "Close trades" block that could close a trade that is just created. But this depends on many factors - the signals in "Condition" blocks, the settings in the blocks. You don't want to create a trade after some conditions and then after the similar conditions to close the trade on the very next tick, if not in the current one.
