To prevent partial execution of orders for stocks, bonds, and other securities, you can use the 'All or None' (AON) feature when placing your order with Interactive Brokers (IBKR). This feature ensures that your order will only be executed if the entire quantity can be filled. Here is how to use the AON option:
- When placing your order, look for the 'All or None' checkbox on the order entry screen.
- Tick the 'All or None' box to activate this feature.
- Submit your order as usual.
By selecting the AON option, your order will remain active in the market until one of two things happens:
- The entire quantity of your order is filled
- You cancel the order
Note
- The AON option may result in your order taking longer to execute or potentially not executing at all, especially in less liquid markets or for large order sizes. However, it provides you with more control over your trade execution and helps avoid unwanted partial fills.
- The AON order type needs 1,000 shares available in the Bid or Ask Size plus the order size for IBKR to route out the order.
- An All-Or-None stock option order needs 10 available in the Bid or Ask Size plus the order amount for IBKR to route out the order.
