We posted this in the release notes, here on the thread and have sent every customer a mail

Important note regarding the just introduced Bollinger Band Bot:

“The new Bollinger Band bot is in beta and we advise you to not trade with large amounts with it until all issues have been resolved. It turns out in certain circumstances when bad data is delivered by exchange APIs that its new spot order type can be triggered erroneously. In a subsequent patch release we handled one such case but there may be more.

Another thing to note is that although there is stop loss available on the bot, there is no Min Effective Gain which given certain parameters and market conditions can mean that sometimes a loss making cycle is executed by the bot.

We broke our necks to get this release out and that coupled with record numbers of new customers means I have to give my team a break over Christmas so that we can come back strong after the holidays and make all the improvements and, indeed, introduce new features going forward.”

Without seeing the logs I cannot say for sure, but it looks like you are running into this issue.

We hope to have a fix out in the next few days.

Best wishes,
Jonathan

I'm interested - do you have the warranties on the cards?
