Traders Magazine By Richard Labs , CPA, CFA, Co-Chair, FIX Algorithmic Trading Working Group (FIXatdl), FIX Trading Community and CL&B Capital Management LLC. It’s been more than ten years since FIXatdl™ had its last upgrade. FIXatdl version 1.1 (released in 2010), achieved its main objective: standardizing the specification of algorithmic order types into a machine-readable XML format. Its scope covers pre-trade analytics, order build workflow, local validation, and finally, submission of a FIX message over the wire. That was a large area to cover in such an early version of a standard. Version 1.0 addressed the needs of algo providers, but it wasn’t until version 1.1, when several OMS/EMS providers were brought on board and started coding against v1.0, that things really took off.
