Tape Reading Academy
Tape Lab replays real market bars one candle at a time. You place orders, manage the position, and find out whether your read was right — with simulated fills, no broker, and no live feed.

What's inside
Every page attacks the same question from a different angle: can you read what price is doing, and can you act on it without talking yourself out of it?
Step through bars at 0.5×–100×. Market, limit and stop orders, stop-loss, take-profit, flatten, reverse. The future is never revealed to the UI.
COREHide the chart and call the next move. Your calls get scored — so you learn whether you can actually read it, or you only recognise the shape afterwards.
HONEST FEEDBACKDelta, CVD, volume-at-price, spread, microprice, aggression, and a top-10 DOM with imbalance, stacking, pulling and sweeps. Five blind scenarios, answer hidden.
ORDER FLOWTagged historical setups you can jump back to and replay until the read is automatic instead of deliberate.
REPETITIONImport your own 5-minute NQ/ES CSVs. Parsed in your browser, stored in IndexedDB, never uploaded anywhere.
YOUR DATAEvery simulated trade with your notes, tags and screenshots. Exports to CSV so the record is yours.
PROCESSA multi-factor replay score — process, risk and read quality — not just whether the trade happened to make money.
GRADEDVWAP, custom-length EMAs with their own colours, opening range, full performance statistics and keyboard-driven stepping.

The course takes about an hour. The terminal will take considerably longer to be good at — which is the point.
