Backtesting that charges you for everything the market would
A backtest is only useful if it is honest. The Lab replays your rules on years of 1-minute data for 900 Binance perpetuals, prices every trade after fees, funding and slippage, models liquidation, and tells you plainly how much to trust the result.

What every trade is charged
A backtest runs under an execution profile: one broker's fees, slippage, funding, leverage caps, lot and tick rules, account currency and liquidation model. The default profile models Binance USDⓈ-M futures. Nothing is optional and nothing is left at zero by default.
Fees and slippage
On every entry and exit, so a strategy that trades often pays for it.
Funding
On every position held across a funding time.
Instrument rules
Each coin's lot size, tick size and leverage cap apply, so an order the exchange would refuse is refused here too.
Liquidation
, modelled for isolated and cross margin: a position that would have been liquidated is liquidated, not rescued by hindsight.
The data is already there
The Lab holds years of 1-minute bars for 900 Binance USDⓈ-M perpetuals, with funding rates and instrument data, refreshed twice a day. You choose coins and dates; there is nothing to download, clean or store.
A run can replay 1-minute bars, use the trade tape for exact stop and target fills, or work at trade level. A run says when a coin did not have enough history for a filter to be ready, instead of quietly trading without it.
A report that says where it works
Each run produces a full strategy-tester report with a chart of every trade. Beyond the headline numbers it breaks the result down so one lucky stretch cannot hide.
Market regimes
Every trade is grouped by the market it entered in (bull, strong bear, weak bear, sideways, with a high-volatility flag), so you see which conditions paid and which did not.
By coin and by period
Whether a few coins or a few days carried the result.
A verdict in plain words
From “Made money broadly” to “Lost money”, including “Too few trades to tell”.
An evidence meter
That reads Not enough, Weak, Moderate or Strong, because ten trades are not a result.
A leverage audit
Showing the caps that applied to each coin.
Optimization that checks itself
When you search for better parameters, the optimizer offers grid, random, genetic, TPE, CMA-ES and NSGA-II searches, and validates with a holdout period and walk-forward testing. It shows heatmaps, parameter importance and how stable the neighbourhood around the best settings is, and reports Monte Carlo resampling, the probability of backtest overfitting and the deflated Sharpe ratio. Read about overfitting in backtests.
