the fees on this exchange (crypto-trade) are 0.2%, so if the trading range for the bot is 1%, the bot still makes 0.6% per cycle( 0.2% up+ 0.2% down would account for the other 0.4%)
oh I know 
I do it by hand, Mark got me started on it, I haven't taken the time to do a bot yet and really recently it's been kinda level for DVC though it is getting closer to my buy limits Would be nice to see a good bot script open sourced, that wasn't just a shotgun bot. The earlier algo posted looked interesting too, would be nice to see that transformed into Python... So much to do, so little time!
