Increased Errors with Order Processing in Paper Trading

Incident Report for Tradier

Resolved

During the first part of the morning session, we observed elevated errors in the paper trading system, with some users receiving HTTP 500 errors when submitting or modifying orders and others having orders remain in a pending state longer than expected. We worked with our OMS partner to resolve this issue and clear all pending paper trading orders.

Live trading was not affected.
