Hello Dhaval,
I presume this is the project you opened to cover what we were discussing in our messages back and forth. It has been years since I have used the GAIN Capital API. I will have to review it some before I begin. If the project will take far longer than anticipated, I may have to adjust my bid, but I believe I can do it for the price specified.
By the way, GAIN / OEC also support the FIX protocol. It is a universal protocol for professionals and is supported by a number of brokers. Many charge extra to use it, but if you would prefer, we could program for that instead. However, FIX protocol would probably take twice as long to complete and would require a different bid.
