TapeSim replays real US stock 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.
Start with a 7-day free trial — cancel anytime before it ends and you won't be charged. €50/mo after.
Everything you need to read order flow
A trading-terminal layout built for one thing: learning to see what the tape is telling you.

Real depth & tape
