Not taking it means you're the gambler, not the casino! Can the dealer at a blackjack table in Vegas step back and say, "I don't really like the looks of that guy, I'm not gonna deal this hand"? I don't think so.
I should also add that this is an excellent point that I want to make sure you know I haven't overlooked. Its at the core of having a trading plan and working it properly.
Given that I've added a few filters, and given that I'm taking trades off overnight levels in addition to my regular RET entries, I just haven't worked out enough yet if these trades do have a positive expectancy. So I just gotta solve this part first and then I can work it! I am not just focusing on one thing, but got a few on the go, so I gotta make sure that I'm building metrics for each individually.
