Slippage in Crypto Derivatives
Slippage is the difference between the expected price of a trade and the price at which the trade is actually executed. In cryptocurrency derivatives, this often occurs due to insufficient market depth or high volatility, causing the order to be filled at less favorable price levels.
When a trader places a large order, it consumes available liquidity at the best bid or ask, forcing the execution to move further down the order book. This phenomenon is particularly pronounced in decentralized exchanges or low-volume perpetual futures contracts.
Understanding slippage is essential for accurate backtesting, as failing to account for it leads to overestimating strategy profitability. It is a direct result of market microstructure, where order flow imbalances dictate price movements.
Traders must optimize order routing and size to mitigate the negative impact of slippage on their returns.
