biaX reads your fills: hold time, add-buys, position size, and the emotion you tagged on each trade. Statistics from your own records. No score, no signal, no advice. A position is down 8%. The thesis hasn't changed, so you add. That decision leaves a specific footprint in your trade data — and biaX is built to show it to you. biaX is a trading-behavior analytics app: a daily retrospective mirror for how you act while trading, across US stocks, Korean stocks, and crypto. Connect your brokerage (read-only) or log your trades, tag them, and biaX surfaces the patterns — your holding-time distribution, how often you re-enter after a stop-out, where your exit timing skews. What biaX is not: not a P&L tracker, not a signal service, not a robo-advisor, not a course. It never tells you what to buy, sell, or hold. It doesn't promise returns. It's grounded in behavioral-finance research — the disposition effect (Odean), loss aversion (Kahneman & Tversky), the sunk-cost effect (Arkes & Blumer) — translated into the patterns that appear in your own fills. We don't promise profits. We show you your behavior. What you do with it is yours. ---------------------------------------------------------------------------------------- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://biax.app/privacy
