  ## History
  
  Davidge, founded 1982, was acquired by S1 Corporation, a holding company, in April, 2000, for about $20 million, at a time when it seemed that "banks in the U.S. were going to control much of the retail brokerage" industry, especially as related to online trading. S1 sold Davidge to Paris-based GL-trade in October, 2003.
  
  At that time, Davidge software was used for "40% of US listed options volume and served "40 New York Stock Exchange members ... and several of the 10 largest brokerage firms."
  
  Their international order routing includes Canada and Britain.
