Looks Nice. Do you find yourself trading bitcoin often?
I am unfamiliar with the bitcoin bot atmosphere but I am guessing it isn't a stretch to assume that other bots exist, what made you decide to write your own?
I built this bot during the winter of 2013/14. Back then I remember being able to find open source bots only for cross-exchange arbitrage. What I needed was something simple and purely for speculation (plus for Bitstamp). Nowadays the bot scene might be very different, and also BTC price is much more stable.
