I can see your EA and I can tell you what doesn't look good with it.
First, take a look at this, because some of your blocks have no chance to run and they need to be disconnected from the Buy blocks: https://fxdreema.com/tutorial/builder/things-not-to-do#2
I see you have "No trade" at the top, which would pass if there is no trade from the current symbol. But since you either have 0 or 2 trades at a time, this is not a problem... but could be a problem if you plan to be able to have only 1 trade from symbol that is not the current. So take a look at this:

Bucket blocks can work... but better connect them one after another and disconnect them from the Buy blocks. I don't think that what you ask for in "Condition" is good. The chance is that in all times the profits from both trades are different, even with one cent, so basically the block will always pass and is useless. I think you want to add something like "+10" in the Adjust field of one of both sides, so you can check if the profit of one trade is bigger that the other with 10 (dollars). And another similar Condition for the opposite case.
