With an extensive experience of more that 10 years using Python in the most various environments, very often in the context of highly computational tasks involving the evaluation of complex conditional variables as it is usually found in online trading routines, we could surely implement your trading strategy wih precision and efficiency and even design it in a way that makes it easy to extend and customize it in the future, as it will probably need to do. We know the requirements of a trading program from our past works on the MT4 platform, on which we have coded several EA and custom indicators for different customers. The OANDA API ist a fully standard HTTP REST API, as many others we are used to work with, and thus it would not represent any problem for us to master it in depth and access it for you in an efficient and secure way.
