After reading reviews about your bot,I am excited to buy it but on a second thought I would wait further and watch as there may be some chance of this bot getting banned by Poloniex
That's a troll, as long as your bot does not more then 6 API calls per second you wont get your IP banned. The more trades you do the more fees they cash, no way any bot is gotta banned (I am using CAT, haas and GUNBOT actually)
Anyway great cake Gun: running smooth since 2 weeks and got good profit. I will post screenshots soon

You are right, i checked all over the exchanges, none is against "automated trades" aka "bots". That's why there is an API for that and they all state that in their API tos, eg
CEX.IO provides several API solutions for automated trading based on needs of individuals and institutions.
Please note that CEX.IO API is limited to 600 requests per 10 minutes. If you are interested in increasing limits, have any feedbacks or feature requests, please drop an email to
web@cex.io.
ReferenceDont worry, none of these bots will ever get banned (as long as they behave

)
