@joelvai could you add a specific error warning to the GUI to notify the user that there is an unsufficient balance in the account?

from Digital Lucifer - this was on windows, binary install of latest DEXBot

This is related to SO logic, generally this should not happen. Looks like there is some rare condition when it tries to go out of balance.

Like @bitfag said, this seems to be a rare condition. Reproducing this would help to fix it properly. One solution would be to raise @gui_error in bitshares_engine.

[bitphage]

I have an idea why this could happen, but a few log lines from dexbot.log before the traceback would be helpful.

Like @bitfag said, this seems to be a rare condition. Reproducing this would help to fix it properly. One solution would be to raise @gui_error in bitshares_engine.

You just have to run with latest binary/install on Windows DEXBot, create staggered orders worker and wait for balance to be depleted.

This is not a windows-specific error as strategy logic is platform-independent. The error probably caused by self.check_min_order_size() correction, which is happening only in specific conditions.
