How can I access the automated order processing systems of the Amex?
All orders must be sent by a member, be sponsored by a member or be on behalf of a member. Access to the Amex’s Reg NMS electronic trading platform AEMI, or the firm’s floor broker through the Booth Automated Routing System (BARS) is available via the Financial Information Exchange (FIX) Protocol or the Securities Industry Automation Corporation’s (SIAC’s) Common Message Switch (CMS). The distinction between orders sent using CMS or directly via FIX is significant. First, FIX customers should experience considerably faster turnaround times compared with CMS. Second, some features will be offered to FIX users only, such as six electronic cross order types and Hit or Take orders. For Financial Information Exchange (FIX) Protocol requirements for the Amex, contact Edward Hayes of the Amex Transaction Services department at 212-306-1962. For Common Message Switch (CMS) interface requirements for the Amex, contact Jim Wieman of SIAC’s CMS support staff at 212-383-7106.
