Amex is asking its order flow providers and aggregators to upgrade from CMS to FIX connectivity with the Exchange by August 31st, 2007. The Exchange gave reasons for this request in a letter from Amex Chairman and CEO, Neal Wolkoff. A copy of the letter is available at http://www.fixprotocol.org/documents/3465/NW%20to%20Members%206%2028%2007.pdf
