What made you stop overtrading?

Overtrading is one of those things everyone understands but still does.

For me, it usually happened after one good trade. I’d feel sharp, then take another setup that wasn’t really there. Then the third trade would just be me trying to recover from the second one.

One good trade can turn into a bad day fast.

What helped you reduce overtrading: strict rules, smaller size, walking away, or something else?
