In the terminal log, MoonBot saw an entry like: “[400] ab not enough for new order”, what does this mean?

An error in the MoonBot terminal log of the form: [400] ab not enough for new order means that there is not enough available balance (ab = available balance) or available margin to open a new order for the selected coin. Check the available balance on the exchange account and top it up if necessary. Make sure that the funds are not occupied in other orders or positions. Reduce the order size if there are not enough funds. Check if the funds have been blocked for other obligations.
