1. Pick a market and load your data
Connect Binance (public crypto data, browser-side download), EODHD (your API key — global stocks and FX), or JQuant (your API key — Japanese equities). Pick a date range and you are in.
2. Scrub through history bar by bar
Hit play and watch the market unfold. Fast-forward the boring stretches. Slow down at the inflection points. Switch timeframes, drop indicators, draw your levels — exactly the workflow you use live.
3. Place practice trades like the real thing
Buy, sell, set stops at any bar — entries, exits, sizing, the lot. Every fill is captured. It feels like the real account, except a wrong call costs you nothing.
4. Track your edge across every session
P&L, win rate, drawdown, average trade. Compare sessions, compare markets, find the setups that work for you and the ones that don't. Practice with intent.
