PROD Release date: October 7th, 2024

Release Type

This release will impact platforms who currently support DAY order types in the Central Limit Order Book

Summary

The Zero Hash Central Limit Order Book will now automatically expire DAY orders at the end of our established trading day, ending at 4:00PM Eastern (New York). This improvement will remove the need for platforms to handle the expiration of DAY orders independently, as our matching engine will expire these orders at 4:00 PM Eastern (New York) automatically, and send the Done for Day execution report via the corresponding FIX gateway.
