Trying To Trust my Indicator and Not Tricked by Price Movement

Too often, My indicator catches the move but I THINK and don't trust it. Trying to just watch the indicator and "use the force"! You can check the results of what happened on your own charts. I totally would have caught that big drop but I was sleeping and I would NOT have shorted it ANYWAY because I didn't trust what my indicator was telling me!!

FYI, I drew ALL the arrows only looking at the lower indicator. I've used this technique before and it works but you have to take ALL the signals - GOOD or BAD. Because you NEVER know which one will be a winner or a loser.
Lot's of losing trades but it will catch +75% or more of EVERY big move. Haven't figured out how to automate it or even test it.

YELLOW arrow is if I would have cheated and got in early, BEFORE confirmation of GREEN arrow.

Trying to catch EVERY signal on the 15 minute chart. In mu opinion, the best time-frame to ENTER and EXIT a trade. Only problem is the activity BEFORE the trade starts to finally go!
