I know what you mean. I've missed trades in the morning and I couldn't stop thinking about it
whether I realized it or not. Then I spent the rest of the day chasing the short in other instruments
because I was still hung up on missing the one earlier. That's a losing day for anyone, every time.
Gotta stick to your strategy and wait for price to hit a price that you like.
Then just manage the risk and don't let a loser run. When price goes your way, then
manage the winner, don't cut it short. Simple thoughts for an often difficult task.
