The trading lesson that saved my small account wasn't an indicator. It was sizing.

What I do now:
• Risk at most 1–2% of the account on any single trade
• Decide the exit before the entry, and write it down
• No adding to a losing position to "average down" on impulse
• After two losses in a row, I stop for the day

With a small account it's tempting to go big to make it "worth it". But one oversized loss can wipe out weeks of discipline, and a 50% loss needs a 100% gain just to get back to even.

Small, boring, repeatable. That's how the account survives long enough to grow.

What's your one non-negotiable risk rule?
