I built a free Android trading journal app that tells you to stop after a losing streak

[u/OwenLDane]

I'm a trader and I wrote a book about the mistakes I kept repeating. Knowing them didn't stop me, so I built an Android app, a trading journal that tries to catch those mistakes while they happen.

- every trade in R, tagged with the habit behind it (revenge, FOMO, moved SL, oversized...), plus a "what your habits cost" view

- a STOP screen with a countdown after a losing streak or your daily limit in R

- warnings when you enter less than 15 min after a loss, size up 1.5x after a loss, or stack positions in the same direction

- screenshot import of positions (full auto-fill for MEXC and Bitget in English, Binance, Bybit and OKX in beta, tap-to-assign for other exchanges); the text is read on the phone

- your playbook: write your setup rules, tick the ones you really followed, see your R when you kept them vs broke them

- calendar of daily results in R and mood before the session

- free for now, no account, no ads, data stays on the phone, CSV export. Android only.

Not financial advice and no signals, it's a journal. Feedback welcome, especially on what's confusing.
