 How to make money in OKEx contract trading?

Investors can obtain the income generated by the rise and fall of the "target" price through buying long or selling short contract transactions, which is contract trading. For example, when you are bullish on BTC and go long, the rise in BTC price will bring profits, and the fall will bring losses; conversely, when you are bearish on BTC and go short, the rise in BTC price will bring losses, and the fall will bring profits. Therefore, there is also an opportunity to gain profits when Bitcoin falls, and earn gains from the rise and fall through contract trading.

OKEx provides two types of contract products, delivery contracts and perpetual contracts, depending on whether there is an expiration date. The delivery contract has a delivery date. When the contract expires and is not closed, regardless of the profit brought by the contract, it will be closed according to the arithmetic average price of the index price in the last hour. According to the delivery date, the delivery contract is divided into weekly, biweekly, quarterly, and biquarterly delivery contracts. Perpetual contracts have no delivery date and never expire. Because the price difference of the underlying returns to a reasonable expectation, if there are more users on the bullish side, the bullish side needs to pay the funding fee to the bearish side, and the bearish side obtains the funding fee income; if there are more users on the bearish side, the bearish side needs to pay the funding fee to the bullish side, and the bullish side obtains the funding fee income.

In the two large modules of delivery contracts and perpetual contracts, they can be further subdivided into USDT margin delivery contracts and currency-based margin delivery contracts according to the margin type; USDT margin perpetual contracts and currency-based margin perpetual contracts. A small amount of funds paid at a certain ratio according to the contract price as a financial guarantee for the performance of the contract is the contract margin. The distinction between margin types allows users to freely choose the basic digital currency USDT as margin or the currency corresponding to the currency pair as margin when trading.
