that is great, I guess I will use your service later on. besides IB, tradestation is another broker providing broad market access. wish you could include tradestation in the package. I do not know other traders, I quite concern if my trading strategy would be reverse engineered. lots of people say it is impossible to decode a trading strategy, but I know it is easy to decode mine within a few hours. lots of profitable trading strategies have very simple logic.
Using some mobile API via your phone is a terrible idea and scraping is even worse. Scraping is a last resort sort of thing - used only for non-critical stuff. And having an API has nothing to do with HFT, you could be planning weekly positions with an API and I'm sure some do. Manually clicking in many orders is slow and error-prone and uh, unnecessary.
