Unlike a perpetual contract, a Quarterly Contract is a contract with settlement and delivery, and uses USDT as the underlying asset, quote, and settlement currency the same way as the USDT contract. Its price formed entirely by the market price mechanism, and the profit and loss are calculated by using the last price instead of the index.
Since USDT is used as both the quote and settlement currency, is the only asset that exists in the Delivery Account and can be used to trade other digital contracts directly, which can reduce the loss in multi-currency exchanges. Of course, your profit is also settled by USDT.
Compared with BTC, EOS and other digital currencies, which may result in the increase in currency amount and the decrease in value of assets due to digital currency depreciation, USDT is relatively stable in the long term run. As both the quote currency and settlement currency, USDT can reduce the abovementioned risk in transactions.
Currently, the Quarterly Contract is a quarterly contract (except HT and BNB) and will be delivered at 17:58 (UTC +8) on Friday in the last week after three months, during the period, the weekly mark-to-market occurs at 17:58 (UTC +8) on every Friday.
