a bug in code?

        if closedvalue > 0:  # long position closed
            closecash /= comminfo.get_leverage()  # inc cash with lever

It seems that you forget to handle the condition of short position closed.

line 642:

        if closedvalue > 0:  # long position closed
            closecash /= comminfo.get_leverage()  # inc cash with lever
        else:  # short position closed
            closecash /= comminfo.get_leverage()  # inc cash with lever
            closecash = -closecash

line 674:

        if openedvalue > 0:  # long position being opened
            opencash /= comminfo.get_leverage()  # dec cash with level
        else:  # long position being opened
            opencash /= comminfo.get_leverage()  # dec cash with level
            opencash = -opencash

The code is for sure prone to contain bugs, but rather than isolated code lines

Do you have a small test sample that shows that there is a bug there?
