Delivery Period

The designated period in which holders of short positions give notice of their intention to deliver on the exchange. In a COMEX delivery month, for example, the delivery period starts two days after the last trading day of the previous month and extends one trading day beyond the delivery month.
Heavy liquidation of long positions often takes place just prior to delivery periods to avoid the liability of having to accept gold or warehouse receipts; that is to say, the longs bail out a day or two before delivery may be forced upon them in the delivery period.
