Thanks, someone should make a trading platform that uses this stuff+TALib+MTGox.
I'm on the case. Making a windows charting/trading app.
It downloads the complete trade history just once, then it bins all trades into 1 minute bins (finding open/high/low/close/vol) and stores on local disk. Then it updates realtime once per min. this way no duplicate data is requested from server and you get a hi resolution realtime chart.
The data is displayed as 1 min chart, you can zoom out to show all data and zoom in to show 1 min data. Zoom is continuous.
Chart includes technical analysis overlays and underlays.
Also includes a predictive neural network that is configurable, once trained it predicts future movement (not perfectly but way better than a coin flip).
You can put yourself between trade signals and the buy/sell button, or you can let it do full auto trading as a bot and it interfaces to the MtGox trade API. Includes stop loss function.
Also you can pull daily OHLCV data from yahoo finance to check out any other security/index.
