Time travel for the market
StockReplay rewinds the market to a real trading day of your choosing. You see only what investors saw at the time — no tomorrow's prices, no answer key. Then you play forward, one day at a time, and find out if you were right.
Drag the dial or click a year to jump straight to it — prices shown are period-accurate examples.
How it works
No shortcuts, no preview of the next chapter. You experience the market in the same order it actually unfolded.
Any trading day from 1926 to today. Start on an ordinary Tuesday, or jump straight into a historical turning point.
Place orders with exactly the information that was public that day — prices, filings, and front pages, nothing else.
The market reopens the next morning. Trade, hold, or sell — but you can never see further ahead than the new day you've just reached.
