How to play OKEx's perpetual contract? How to calculate the funding rate?

OKEx is one of the leading cryptocurrency exchanges that offers a wide range of trading products, including perpetual contracts. Perpetual contracts are a type of futures contract with no expiration date, allowing traders to hold positions indefinitely. In this article, we will delve into how to play OKEx's perpetual contract and how to calculate the funding rate, a crucial component of perpetual contracts.

Understanding OKEx's Perpetual Contract

Perpetual contracts on OKEx allow traders to speculate on the price movement of various cryptocurrencies without owning the underlying asset. These contracts are designed to track the price of the underlying asset closely, but they have a unique feature called the funding rate, which helps to align the contract price with the spot price.

To start trading perpetual contracts on OKEx, you first need to have an account and complete the necessary verification processes. Once your account is set up, you can navigate to the futures trading section of the platform.

Opening a Position on OKEx's Perpetual Contract

To open a position on OKEx's perpetual contract, follow these steps:

• Log into your OKEx account and go to the futures trading section.
• Select the cryptocurrency pair you want to trade. OKEx offers a variety of pairs, such as BTC/USDT, ETH/USDT, etc.
• Choose the leverage you want to use. OKEx allows for up to 125x leverage on certain contracts.
• Decide on your position size and whether you want to go long (buy) or short (sell).
• Place your order. You can choose between a market order, which will execute immediately at the current market price, or a limit order, which will execute at a specified price.

Once your order is filled, you will have an open position that you can monitor and manage from your trading dashboard.

Managing and Closing a Position

After opening a position, you can manage it through various tools provided by OKEx. You can set stop-loss and take-profit orders to automatically close your position at predetermined price levels, reducing the risk of significant losses.

To close a position, you can:

• Go to your open orders in the futures trading section.
• Select the position you wish to close.
• Choose to close the position either partially or fully. You can also set a market or limit order for closing.

Understanding the Funding Rate

The funding rate is a key mechanism in perpetual contracts that ensures the contract price stays close to the spot price of the underlying asset. The funding rate is exchanged between long and short positions periodically, usually every 8 hours.

How to Calculate the Funding Rate

The funding rate is calculated using the following formula:

[ \text{Funding Rate} = \text{Premium Index} + \text{Clamp} (\text{Interest Rate} - \text{Premium Index}, 0.05\%, -0.05\%) ]

Where:

• Premium Index is the difference between the perpetual contract's price and the spot price, averaged over a period.
• Interest Rate is a fixed rate that reflects the cost of capital.
• Clamp function limits the value within a specified range.

To calculate the funding rate, OKEx uses the following steps:

• Calculate the Premium Index: This is done by taking the average difference between the perpetual contract price and the spot price over a certain period, usually every minute for the last 8 hours.
• Determine the Interest Rate: This is a fixed rate set by OKEx, typically around 0.03% annually.
• Apply the Clamp Function: The clamp function ensures that the difference between the Interest Rate and the Premium Index is within the range of -0.05% to 0.05%.
• Calculate the Funding Rate: Add the Premium Index to the result of the clamp function.

Example of Funding Rate Calculation

Let's go through an example to understand how the funding rate is calculated:

• Premium Index: Suppose the average difference between the perpetual contract price and the spot price over the last 8 hours is 0.02%.
• Interest Rate: OKEx sets the interest rate at 0.03% annually.
• Clamp Function: The difference between the Interest Rate and the Premium Index is 0.03% - 0.02% = 0.01%. Since 0.01% is within the range of -0.05% to 0.05%, the clamp function does not alter this value.
• Funding Rate: The funding rate is calculated as 0.02% + 0.01% = 0.03%.

In this example, the funding rate is 0.03%. If you hold a long position, you would pay this rate to short position holders, and vice versa if you hold a short position.

Monitoring and Adjusting to Funding Rates

It's important to monitor the funding rate because it can significantly impact your trading costs. If the funding rate is positive, long position holders pay short position holders, and if it's negative, short position holders pay long position holders.

You can adjust your trading strategy based on the funding rate. For instance, if the funding rate is consistently high, it might be more profitable to hold a short position and collect the funding payments from long position holders.
