CryptoFacilities, Coinpit, and BitMEX has a realtime profit realisation, while OKCoin and Deribit has weekly rebalancing scheduled for all contract lengths. It's important to note that on all of these exchanges, all the futures and forwards are non-deliverable and have expiration at various times. Despite this, OKCoin uses "delivery" as their term for expiration settlement of a contract, and "settlement" for the weekly rebalancing of the Pnl for higher length contracts.
