How to avoid over trade?

This. You have those easy days, and you have those hard days. Take the easy ones when you can, because those hard ones can strike anytime.

Sometimes, its looking like, " Count your lucky stars" that you profited, and call it a day.

If your system calls for the signal, trade it as per your system. But when you hit your goal or target for the day, and hey, maybe for the week. Wrap it up, call it a day.

And, it can be hard to do. This is when self control comes in, and you have to just let it go, lol… Enjoy the day, find something else to do.

Overtrading = Squeezing trades not on par with your system,
Overtrading = Daily goals accomplished but continue to look for trades.
Overtrading = Trading just to kill time.
