Maintenance Updates

Bybit will adjust the minimum ask price (MIN_ASK) calculation mechanism for short-dated Options on 

. This update aims to improve quote stability and strengthen risk control as contracts approach expiry.

The change applies to Options contracts that expire within 2 days. After the update, the minimum ask price will be determined by the highest value among 3 parameters: the Fixed Minimum Value, the Short-Dated Floor, and the Dynamic Risk Floor. The calculation method for the maximum bid price (MAX_BID) will remain unchanged.

Minimum Ask Price = Max (Fixed Minimum Value, Short-Dated Floor, Dynamic Risk Floor)

This update affects only the minimum ask price boundary for short-dated Options. It does not affect the mark price, index price, Delta calculation logic, or users’ existing positions and margin calculations.

Bybit will continue to monitor market conditions and optimize related risk control mechanisms when necessary.
