LimLims, I would think that most people hold that information close to the vest.   There are some simple API's and Bots out there but they are very limited.  One can be found at https://github.com/alanmcintyre/btce-api... It looks safe enough but Im no programmer so I couldn't tell you if it had something hidden in it.   My partner is the programmer in our group and yes... we don't just rely on the API.
