Execution Variance

Definition

Execution Variance refers to the deviation between the intended or quoted price of a trade and the actual price at which the trade is executed. This discrepancy arises from market microstructure factors such as latency, slippage, and liquidity fluctuations between order placement and fulfillment. In high-frequency trading and volatile markets like cryptocurrency, managing execution variance is critical for preserving trading strategy alpha. Minimizing this variance directly impacts overall profitability.
