TapeSim replays real market data — depth, time & sales, and the DOM ladder — tick by tick, so you can rehearse order-flow trading and place simulated orders without risking a cent.
Beta runs on Lemon Squeezy test mode — no real money is charged. At checkout, use the test card 4242 4242 4242 4242, any future expiry, any CVC.
A trading-terminal layout built for one thing: learning to see what the tape is telling you.
Replay genuine Level-2 book updates and time & sales prints from recorded market days — not synthetic noise.
A live price ladder with volume profile, streak fades, and cent-snap. Click to place simulated limit orders right on the ladder.
Scrub, pause, and step through a session at your own pace. Watch absorption and exhaustion unfold in slow motion.
Place orders against the real flow and see realistic fills, position, and live P&L — no broker, no risk.
Download market days straight from inside the app and build a library of sessions to drill on.
A fast, native desktop app — not a laggy web chart. Built for tape reading at full speed.
