I am working on intraday data also and my present strategy tanked heavily in the last 10 days (I failed to place an order on Monday and that's striking hard).
I am also working on the fastbt library and preparing a web interface to try things out.
My research so far has shown that the chances of winning in intraday by retailers are slowly turning out to be negligible and the only way to make some money is to go long and short almost all the time and also spread your investment horizon over different time periods
