Only receiving Participants can cancel a recycling PTA transaction. Delivering Participants of PTA transactions that recycle for Risk Management Controls cannot cancel them. The position associated with cancelled PTA transactions is automatically released from the PTA account and made available to the delivering or pledging Participant for other PTA or non-PTA transactions.
Receiving Participants can cancel only PTA transactions that recycle for Risk Management Controls (including PTA transactions that recycle for insufficient other NA). Only delivering Participants can cancel non-PTA recycling deliveries and PTA deliveries recycling for insufficient position.
