One of three things gets me out of a trade: 1. I hit my profit target, 2. I hit my stop-loss level, 3. My Indicator Package reverses from the trade entry profile (thus my reasons for entering the trade are no longer valid). YMMV, I wish everyone good fortune !
Sometimes, you need a tad more room and 3pts on NQ saves you from a loss, you'd just have to get back in again anyway, I prefer to reduce the cost of being wrong, but at times it goes the other way. Sometimes I close a position at a loss, before it hits the SL, upon realising on the wrong side of the momentum. Sometimes, I sit there, can't function and do nothing but HOPE, that's why my account gets slapped silly LOL
One thing I found helpful is to tighten up trailing stops near noon , since sometimes there's big reversals A or V shape. Also at 3:30
You should try placing your stop loss close to the entry. This will increase the probability of profits even more for you. Good luck.
