Dear Sir,
I have both rich expertise in programming for financial markets and trading platforms in C++, C# programming languages and deep knowledge of stocks, futures, FX trading. I have developed backtesting tools for FX and equities markets. And I also have written several black boxes which use API of brokers for automated trading. I am familar with Interactive Brokers API and able to develop such automated trading tool according to your requirments except "backtesting" feature because typically backtesting is implemented separately from the automated trading tool and backtesting is separate large task by its nature.
Looking forward to hear from you.
Thanks & Best regards,
Denis
