I'm Jinhyun. I built biaX because my own trade log kept telling me things I'd rather not read. Every journaling app I tried asked me to write down how I felt, then showed me a P&L curve. Neither told me what I actually did — how long I held the ones that worked versus the ones that didn't, whether I sized up after a bad week, how many times I'd taken the same entry before. So biaX doesn't ask you to journal. It reads the record you already have — broker connection is read-only, or import a CSV, or type them in — and reports the statistics. No score, no grade, no forecast. The behavioral finance literature (Odean on the disposition effect, Barber & Odean on trading frequency) says these patterns are common and mostly invisible to the person repeating them. Counting is the one useful thing an app can do here. It runs in the browser at my.biax.app, so there's nothing to install if you just want to look — log a few trades by hand and the statistics are the same ones the app shows. I'd rather hear where it's wrong than where it's good. Especially from anyone who kept a trading journal and gave up on it: I want to know what made you stop.
