If you're a client who trades in large size, you'll can accept a partial fill to increase your chance of a successful execution.
If you choose to use this feature, we will only ever partially fill your order as an alternative to an outright rejection. We will never partially fill your order as an alternative to filling it in its entirety. So if you trade in a size so large that we cannot fill your entire order, we will still be able to fill it to the maximum size possible.
If you have selected the partial fill feature, the next time you trade through the same device it will be retained as your default option.
Are partial fills for me?
Partial fills may be for you if you are a client who wants as much of your order filled as possible at the current price, and do not want a size rejection when we cannot fill the entire order.
