For a long time, futures and spots hedging is generally designed to detect the price difference. When the price difference is met, we will take the order to hedge. Can it be designed as maker hedging? The answer is absolutely yes. Today, I will bring you a design idea and code prototype for the maker hedging.
Idea of maker hedging
In different markets of the same or the same type of subject matter, hedging opportunities arise when there is a large difference between the selling orders and buying orders of two markets. Generally, we will do makers that meet the price difference and hold hedging positions. Therefore, there are two purposes for hedging. The first is to hedge the position and the second is to ensure that the difference between the buying and selling order meets our expectations to the largest extent. The advantage of maker trading in this respect is that the comission fee is lower. The disadvantage is that it is not easy to make a deal, and it is easy to make a deal on a single position.
The trading idea we design is to place a buy order in the A market order book and a sell order in the B market order book. Then we check our account pending orders, and do the next step for the checked pending order transactions. For example, if we find a change in the pending order, we balance the hedge position of spots and futures immediately, and cover or close the overflow position in the spots and futures position. According to the increase of the hedging position, we adjust the distance of the first pending order in the order to the next position in the order, and hedge to get a larger spread gradually.
Code design
The comments are written in the code directly. The example is used for reference design only and it has been tested on the OKEX V5 demo. The example is not a perfect strategy, please use it for reference only.

Backtest analysis
We can see that pending orders and withdrawal orders are more. From the backtesting system's statistics, the futures exchange account lost -0.01666 ETH and the spot exchange made a profit of 842.23758 USDT. The ETH spot price was 4252 USDT at the end of the backtest, -0.01666 * 4252 = -70.83832000000001. It obtains profit overall after plus the spot profit.
But it is just on a backtest, and there are definitely more details to be worked out in the real bot.
