Hallo Every Trader, I am a financial engineering and has tried to start my own trading. I love c# and designed a software based on that to help my self to check market and deploy automatic trading strategies. The thing I have done: 1. Based on ActiveX API provided by Interactive Brokers known as a kind broker to provide consistent service. I use c# because it is easy to have some usable UI quickly and I could learn more support from anywhere on Internet. Totally abandoned any opensource, sorry. 2. Try to develop a strategy on Forex and plan to deploy it as an automatic one on my software which will be installed on a seperate software dedicated for trading or on Amazon EC2. 3. Please tell me any suggestion or recommendation on my plan 4. Plan to develop strategies by using SAS data miner and Rapid-i because of its easy to use and lot of data manipulation and modelling tools. Thanks lot!
