@mario-c The only way I know of is opening manually it via another EA and then adding a comment on that EA's buy/sell now blocks. I don't see any other way to do it right now, but maybe I'm wrong.
@mario-c You do not need to create 3 groups when all settings are common. As jstap says, use one only trailing stop block separated from all block trees and then type all three group names there comma separated.
@mario-c The logic is not necessarily wrong, but you are requiring distances to be EXACTLY 90 pips. That will not necessarily happen. A tick can move price from 89 to 91 pips distance. That the block will not be executed. I would use >= instead of == symbol.
