In the MoonBot terminal log, I saw an entry like: “Account has insufficient balance for requested action”, what is it?

: Log errors

The error “Account has insufficient balance for requested action” in the MoonBot terminal log for the Binance exchange occurs if all funds on the deposit are used and an attempt is made to place a new order. The exchange returns this error when the order amount exceeds the available balance on the trading balance.
If your funds are already involved in other orders or positions, the MoonBot terminal will not be able to place a new order and will display this error.
Funds that are not in a trading (spot or futures) wallet, but, for example, in a “Replenishment Wallet”, are also unavailable for trading – an attempt to place an order will lead to a similar error.
To place an order, it is necessary to take into account not only the transaction amount, but also the commission. If the commission is not paid in BNB, but in a traded currency, part of the funds is held against the commission, which may lead to an insufficient balance for a new order.
The error will occur until the required balance on the trading wallet is released.
