Oanda API + Java Standalone app + Testing Framework

I need a Java App that interfaces with Oanda's API to execute trades. Needs to work on Practice account and Real Account. I need an UI that presents basic account information, trade information, parameter selection and ability to start and stop live trading. The app needs to work on the follow requirements(selectable from UI): 1. Time Frame: 1 min, 5min, 15min, 30min, 60min 2. multiple Pairs at once: EURJPY, GBPJPY, and GBPUSD. also obey FIFO rule 3. I need to convert some old meta trader indicators (mql4) into this new program. 4. Executive on given strategy (driven by indicators) 5. Program needs to account for take profit, stop loss and trailing stop Finally, I would need a testing framework built around this app that tests the stand alone app triggered by a historical file. (file format will be provided later)
