Tick Size Constraints

Tick size constraints are the regulatory or exchange-imposed minimum price movements for an asset. These constraints prevent prices from moving in infinitesimally small increments, which could otherwise lead to excessive messaging traffic and system instability.

In cryptocurrency derivatives, these constraints directly influence the cost of placing limit orders and the competitiveness of market makers. If the tick size is too large, the spread may remain artificially wide, preventing tighter pricing.

If it is too small, it may lead to penny jumping, where traders undercut each other by the smallest possible amount. This impacts the overall health of the order book and the ability of large participants to execute trades without significant price impact.
