Paper trading runs your strategy on live, real-time prices with simulated capital. It is the step between a backtest and real money, and it is the one that actually tells you something — a backtest is graded on history it was tuned against, while paper trading faces a market that has not happened yet and cannot be gamed.
Real prices, simulated money#
The value of paper trading is that almost everything about it is real. Only the capital and the fills are simulated.
What is real#
- Live prices — the same real-time feed a live strategy trades on.
- Your rules — signals evaluate on each new candle exactly as they would live.
- Risk management — stop losses and take profits fire the same way.
- Notifications — position changes reach your alert channels.
- A slippage model — fills are not assumed perfect (see below).
What is simulated#
- The capital — you set a starting balance; no real funds are touched.
- The fills — orders are filled on the platform's shared paper exchange rather than a real order book.
Starting a paper strategy#
- From your strategy list, press Paper Trade on the strategy.
- In the Start Paper Trading dialog, set a starting balance —
10,000is a sensible default; position sizing works from it. - Turn on Enabled for Trading in the strategy's Overview tab. That is the switch that lets positions actually be entered — without it the strategy runs but opens nothing.
Your paper trades then appear in the Positions view alongside everything else you trade, with full fund-grade statistics.
A strategy can run on paper and live at the same time. Keeping a paper venue running after you go live gives you an honest, uninterrupted track record to compare the live fills against.
Slippage — fills aren't free#
Paper trading models slippage so results aren't flattered by assuming every order fills at the exact price. Slippage starts at 0.5% and increases by 0.5% on each retry: if an order can't fill because price has moved away, the next attempt allows more slippage until it fills. This mirrors the reality that getting in during a fast move costs more than the mid-price.
Limits#
How many strategies you can paper-trade at once is set by your plan tier. See plans for the limit on yours.
Trading a paper venue by hand#
Paper trading isn't only for automated strategies. You can place manual orders on a paper venue too — Buy, Sell, Close and Flip — from the trading terminal, which is the safe place to learn the mechanics of order entry before any capital is real.
