The FIX Algorithmic Trading Definition Language (FIXatdl) version 1.1 allows the simple, free XML expression of electronic trading capability that empowers automatic generation of rich and dynamic trader GUI.
FIXatdl is built on top of the widely adopted FIX Protocol and allows firms receiving orders to specify exactly how their electronic orders should be expressed. Orders built using FIXatdl can then be transmitted from traders' systems via the FIX Protocol. All versions of the underlying FIX Protocol are fully supported and zero changes to underlying FIX infrastructure are required.
FIX Trading Community publishes the FIX Protocol specifications in Microsoft Word (".doc" or "DOC") and Portable Document Format (".pdf" or "PDF") formats. Any registered user of the FIX Trading Community website may access the PDF version. The Word version is accessible by FIX Trading Community members only. Registration is free. Site users must be logged in to access specifications in either format.
