Finally figured out a viable way to get good trades with OBV based on comparing the OBV slope and the price slope. Doesn't trade too often, but in the past few months it does alright.
It will run on any tick under 2 hours, BTC/USD, but the bot will automatically only run every 2 hours (anything shorter didn't seem to work so well).
**** WARNING: THIS IS NOT LIVE TESTED AND MAY STILL CONTAIN BUGS ****
May - July 2014 it makes $767.71 USD on $1000 at BTC-e
