Mirror Strategy is unable to cover position when balance on backing exchange is low

[nikhilsaraf]

This should never happen because we should consider the balance on backing exchange when placing orders such that we can always cover.

This causes bot to crash.

The result of a low balance should be that we are unable to place orders on that one side (bid or ask) because the available balance from the balanceChecker results in a net 0 order amount.
