Taker Speed Bump

Backpack applies a 100ms speed bump to all taker orders across spot and futures markets.

This reinforces top-of-book liquidity. It protects resting orders from latency-driven adverse selection. It also supports deeper books and better execution for all participants.

How it works

• The 100ms speed bump applies to any order submitted without the postOnly flag. This includes market orders and limit orders, including IOC orders, even if the order ultimately rests on the book.

• Orders with postOnly enabled are not subject to the speed bump.

• Order cancellations are exempt. They are processed without delay.

• The speed bump applies uniformly to all participants

Attempting to circumvent the speed bump violates the Terms of Service.
