A lending order may only be changed if the order has yet to be fully matched. If your order has been partially matched (that is, only a portion of your order has been matched to a loan or series of loans), you can change or cancel the order only in relation to the amount which has yet to be matched.

Login to your RateSetter Account, then click the relevant lending market under "Your Loans and Orders" in the menu on the left.

Finally, expand the box titled "Unmatched", then click "Change" or "Cancel" next to the relevant lending order.
