FIX Log Desk

Paste the FIX protocol session capture you just pulled off an OMS, an EMS or a drop copy and work out what actually happened, in one sitting. A real FIX reader runs free in your browser: it detects the delimiter per message, reads length-prefixed data fields by byte count, recomputes every BodyLength and CheckSum from the bytes, tracks MsgSeqNum per direction, chains ClOrdIDs into orders, walks the FIX order state diagram per chain leg and checks that CumQty plus LeavesQty equals OrderQty. Then run one of four AI lanes over what it found: diagnose the session, reconstruct the orders, judge the fills against the evidence that actually exists, or read the tape for the signatures a surveillance screen keys on.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
