A Cash account must have enough cash to cover the cost of a position plus commissions and can never hold a negative cash balance. When placing a Market order (or Stop order), the order value cannot be known with certainty prior to execution as the market can move in any direction at any moment. Because of this, an extra 5% is added to the order amount at the credit check step for Market type orders to account for market movements. If you receive an order rejection for not enough Settled Cash when you do in fact have the Settled Cash to execute your order at your desired price and quantity, try using a Limit order (or Stop Limit order for a Stop) or reduce the MKT order size…

It is possible for an account holding a Future Option position to have positive Available Funds due to the position's Unrealized P&L yet still hold a negative cash balance. In this example, the account would not be allowed to Buy additional Future Option contracts to add to that position as there would be no cash to pay the seller.

The message "Gross Order Total Exceeded" ("GOT Exceeded") will appear when the IBKR credit limit for the total value of all open orders sent to a specific exchange is reached. Once this current credit limit is reached, the current total order value must be manually reviewed so IBKR's credit limit at that exchange can be increased. This normally happens seamlessly throughout the day but it is possible that this review can take a short time to complete. Once reviewed and the gross total order value credit limit is increased, new orders can then be accepted and routed to that exchange. This is one of many safety features implemented by regulators to try and avoid another "Flash Crash" situation…

When the "Order Preview" for a futures order uses a “Net Liquidation Value” for the order’s credit check that refers to the Net Liquidation Value currently residing in the Commodities segment and any available unpledged equity in the Securities segment that can be swept into the Commodities segment. So the account’s Total Net Liquidation Value number can be different than the Net Liquidation Value number displayed in a future order’s Order Confirmation preview window.  The credit check at the time an order is entered looks at the amount of Available Funds in the account. If the account has enough Available Funds for all current open orders and the new order being credit checked then the order can be accepted…
