Partial fills example
IG’s current GBP/USD price is 15349/15350. You want to buy up to £2000 per point at 15350, but you are worried your order may be size rejected as it is so big.
You submit an order to buy £2000 per point at 15350, and select ‘Accept partial fill’ on the deal ticket.
IG tries to fill you in the whole £2000 per point, but unfortunately is unable to fill the whole size in the underlying market at that price. You receive a partial fill in £1500 per point. If you had not selected ‘Accept partial fill’ your entire order would have been rejected. The remaining part of your order (£500) will be cancelled.
