CoachA speed bump is a fixed delay a venue adds to messages before they reach its matching engine. An asymmetric speed bump delays only some messages, typically those that take liquidity, while cancellations and new quotes pass undelayed, so that a liquidity provider can correct a stale quote before any taker can reach it.
