I just played around with the autobet, and the "Stop if balance >" field is working in a weird way. The number I entered there is automatically divided by 100000000000 for no reason. When I put "1" there, it gives me "0.00000000". When I put "100000", it gives me "0.00000100".
Please reload page and try again. (Was a bug when converting the numbers to the internal representation.)
Thanks for your report.
