How we compute a backtest

Numbers you can argue with, not slogans

A backtest is only useful if you know what it assumed. These are the rules the engine applies to every strategy on the platform — templates, yours, and the marketplace alike.

Real exchange data

Binance and OKX candles, funding rates and open interest, cached locally and pre-warmed. No synthetic prices anywhere.

Next-bar fills

A signal on the closed bar fills at the next bar's open. Limit and stop orders rest on the book and fill only when price trades through them.

Fees and slippage

Maker/taker fees per fill plus configurable slippage. Costs are charged on the way in and on the way out.

Funding and liquidation

Perpetual positions pay real funding each interval; margin is tracked per position and a breach liquidates you, as it would on the exchange.

In-sample / out-of-sample + Monte Carlo

The last 30% of the window is held out. Trades are reshuffled 1,000 times for drawdown and loss-probability bands. The robustness score penalises red flags and losses.

Isolated execution

Python and JavaScript nodes run in a locked-down container with no network and no access to the database or other users.

Data currently available

Only what the engine really ingests today. More feeds are added when they can be backfilled end to end.
