Your Mistakes Have
A Price Tag.
Every profitable trader has a short list of behaviors they're actively fighting — and they track them. Tag every trade with the mistake that caused it. See the dollar cost of revenge trading, FOMO, oversizing, and every other pattern that's bleeding your account.
Start Tracking Mistakes
You know you make the same mistakes — but you don't know what they cost.
Revenge trading. FOMO entries. Moving your stop. You know these habits exist. But without a number attached, they stay abstract. “I need to stop revenge trading” hits different when you see it cost you $2,400 last month.
ohYaaa puts a dollar amount on every mistake category. Create your own list, tag trades as they happen, and watch the data turn bad habits into concrete problems you can solve.

"I tagged 'revenge trade' on 14 trades last month. Total damage: -$3,200. That one number changed everything. I printed it out and taped it to my monitor. This month I had 3 revenge trades and they cost me $180. ohYaaa didn't fix my psychology — the data did."
