Ralph Moses started in futures with Geldermann, helping them use a new IBM mainframe. He later started developing a system called Order Express for Lind Waldock, one of the first electronic trading front ends. He used an IBM System One mini computer with 2 MB of memory. He built a risk management system that could tell if an account was at risk depending on how markets were moving. This helped Lind Waldock avoid significant risk during the stock market crash of 1987.
