is a station trading bot I developed that undercuts competing orders on the market by .01 isk. It has the advantage of being able to earn vast amounts of isk over time, limited only by your starting capital and order limit. It is highly resistant to manipulation attempts with built in volume/price checks and customizable order change limits, and essentially undetectable as it can periodically pause for random lengths of time and works entirely via screen reading, cache file reading, and simulating mouse clicks. As far as I know it's the first bot of its kind to be publicly available. I'd be happy to answer questions about it if anyone's interested.
