## Backtesting Precision

Backtesting Precision is the degree to which a simulated trading strategy accurately reflects how it would perform in a live market. High precision requires accounting for factors like slippage, latency, transaction fees, and market impact.

If a backtest lacks these elements, it will likely overestimate profitability. In crypto, where market conditions change rapidly, precision is essential for avoiding costly failures.

It involves using high-fidelity historical data and realistic execution models. Developers must rigorously test their strategies against diverse market scenarios to ensure robustness.

Achieving high precision is the ultimate goal of the quantitative research process.
