Allow me to give you great exercise to do.
Every time you have an urge to place a trade write down on piece of paper and stick it on your pc.
Come next day and see if it made profit or not chances are not.Place another trade.
Do this whole week and count your losses and profits.You'll find most 80% of your losing trades were Early
You'll feel better knowing it was just piece of paper and not real money.
Its all about timing.
In trading, you have to be defensive and aggressive at the same time
