Hi everybody. I'm interested what kind of trading software would be a big improvement comparing to actual solutions. Let's say there is a software built up from the scratch, solid and sophisticated engineering, fast and very stable. The program has a datafeed (Fix and Fast), certified by a big market gateway, a connection to a broker and a extensive monitoring infrastructure for simulations on historical data and backtesting of strategies. The strategies are written in mathlab, and the software can backtest and trade them. This is a very basic setup and works for example for daytrading S&P 500. But given the idea of a totally modular built of the software, basically every marketgateway and broker connections are possible, also the change from mathlab to C or Excel. As a person with only very limited knowledge of trading, I'm interested what kind of software features people in this business are interested in. What would be a big technical challenge, what would be very interesting but doesn't work yet because of problems with connectivity or other issues? At last some very basic questions, but they might help me to understand the needs of traders a bit better: *Which market gateways are the most important? *How interesting is speed, f.e. real-time trading? *Which language? C, Pascal, R, Mathlab or Excel? *What kind of graphical user interface would be interesting? *Is an encryption of the strategies as a safety feature interesting?
