CLOB FIX Messaging Enhancement: Balance Rejections
January 23rd, 2026
FIX Order Gateway
zerohash is happy to announce a new optional feature to allow CLOB participants to reliably identify NewOrderSingle and OrderCancelReplaceRequest rejections stemming from insufficient balance on the given account.
NewOrderSingles
If enabled, NewOrderSingles rejected due to insufficient buying power now have an OrdRejReason (Tag <103>) of "Insufficient credit limit" with value 25, instead of “Exchange option” with the value 0.
OrderCancelReplaceRequest
Similarly, if enabled, OrderCancelReplaceRequests rejected due to insufficient buying power now have a CxlRejReason (Tag <102>) of “Insufficient credit limit” with value 25, instead of “Exchange option” with value of 2.
