Paper Trading Simulator

A made-up price series over 120 days. You decide: buy, set a stop-loss, sell, or do nothing. At the end you see your result, your win rate, and your expectancy — exactly the metrics from the Risk and Psychology stage.

A new random price path is generated for every round, right in your browser. No real market data is used, and nothing is transmitted or stored. Starting capital: 10,000.

Frequently asked questions

Is this real price data?

No. The series is randomly regenerated every round and does not track any real security. It is meant to show the mechanics and psychology of trading, not to forecast a market.

Is anything stored or transmitted?

No. The simulator runs entirely in your browser. There is no server, no account creation, and no data transmission.

Why only one position at a time?

That keeps the focus on the core decisions: position size, stop-loss, and exit — the decisions that determine success or failure in practice.

Are fees taken into account?

Yes. Buying and selling each cost 0.2 percent, like with a real broker. Without that cost, the simulator would make trading look more realistic than it is.
