The order types used in Synthetix perp v2 are Delayed Orders. All polynomial perp exchange processes are carried out through these orders.
Delayed orders are similar to next-price orders, but with a time delay. Instead of executing an asynchronous 'next-price' order after a semi-arbitrary Chainlink price update, we allow the executor (trader or keeper) to fill the order after a specified amount of time has passed, in addition to a price update.
For instance, if the specified delay is 30 seconds and a price update occurs 10 seconds after the order submission, a keeper can still execute the order, or they can wait for the 30 seconds delay to pass before executing the order.
