I know exactly how you feel, for that has happened to me often enough, being fooled by a down candle when a signal is showing long, and visa versa, and then missing the trade.

What I find helps is to pretend that I have a boss, and I have to show him all my trades at the end of the month, together with the charts for the month.
If there was a signal and no trade taken, then I better have a good reason, and if there was a trade taken and no signal apparent, then there had better be a damn good reason too.

I would say that if I did that more than once, I would risk being fired. My job is to take every valid signal I can, and nothing else.
This helps me anyway.
