With the offering of both spot, margin, and derivatives trading at one spot, OKEx provides users a world-class marketplace which opens the doors to a lot of arbitrage opportunities, saving you the hassle of withdrawing funds from a derivatives exchange to another spot trading platform, also the extra time and costs from blockchain transactions.

Premise

To execute this strategy, we assume the following:

  1. Margin trading interest rate settle with Loyalty Points (70% discount on the secondary market)

Analysis

Essentially, borrow $1000 of TRX with $1000 USDT as margin. Sell $666 of TRX for USDT. Use $333 of TRX as swap margin, buy 66 TRX contracts. Pay transaction fees, spot lending rate and receive swap funding rate.

Starting with a capital of 1,000 USDT on July 15, 2019, the 7-day yield was around 1.66%.

  • The below graphs show that the spot margin daily interest rate was 0.1% from July 15 to 21 and also shows the swap funding rates history.

Note: ­Borrow 1,000USDT-equivalent of TRX. Short 2/3 of it at spot margin trading (666.67 USDT). Then, transfer the remaining 1/3 to perpetual swap account, open 66 swaps which is equal to 660USD. It is almost a delta-neutral strategy.

  • The flow of coins shows a yield of 575TRX which was 1.66% return at the time.

Risk Warning

  1. Funding rates volatility
    For example, if the funding rate at 12:00 July 21 changes from negative to positive, we will have to decide whether to close the position by estimating the next funding rate and the closing fee.

Improvements

  1. Do not hold any positions. Instead, borrow TRX and open position before swap settlement. Then, close the position and repay TRX as soon as possible after receiving funding amount from settlement.
