Improvements

FIX Services

The MX SAIL B3 API upgrade that went live in production on Dec. 19, 2022 made changes on the exchange side to their implemenation of the 'Market' Order Type (FIX tag 40=1).

However, MX exchange failed to obtain regulatory approval for the new Market implementation in time for the production go-live date. As a result, Market orders cannot be submitted for to the MX Exchange in production at this time.

TT FIX clients are able to submit orders using the pre-upgrade Market order type implemention from MX by setting tag 40=K, Market-with-Leftover-as-Limit.

Please contact fixintegration@trade.tt with any questions.
