A local daily spot simulator, using the same engine as the strategy skill. Use the dated Bitcoin series, try synthetic prices or bring your own dataset. Your uploaded data stays in this browser.

Strategy settings

Choose a documented starting point or enter your own frozen rule.

10 basis points = 0.10%. Costs apply to each simulated trade.

Check two separate periods at baseline and higher costs. Each period restarts with the same initial cash.

Execution assumptions

Long-only fractional spot. Signals use observations already seen and execute at the next daily mark. Fixed adverse slippage and fees apply. Final holdings stay marked, without forced liquidation. The benchmark has the same dates, cash flows and costs.

Aggregated daily prices are research marks. They do not model order books, intraday stops, liquidity, funding, taxes or venue fills.

This is a historical research simulation. The Bitcoin series contains public CoinGecko daily marks captured on 2 October 2026, with its retrieval time shown above. The synthetic option describes an invented price path. Bring independently verified historical observations to test a real hypothesis. Results cannot establish future returns or authorize a financial action.
