Startup Idea: AI-Based Automated Trading Program

Startup idea to develop an AI-powered program that automates commodity trading. The system should allow users to formulate, back-test and tweak trading strategies using historical data and various trading indicators. The AI should also be capable of developing profitable trading systems independently.

When I used to trade commodities I looked for a program that would automatically place trades based on specific instructions but was told there weren't any. It would be good if the program allowed users to develop and back-test trading strategies using historical data. One should be able to tweak the system using multiple trading indicators, such as moving average, stochastics, etc... If possible, try to create AI that would try to develop profitable trading systems on its own.
