Better tools make good work – learn to use the research environment to analyze trading principles

The term “hedging” is a very basic concept in the field of quantitative trading and program trading. In the quantitative trading of digital currency, the hedging strategies often used are: futures-spot hedging, cross-period hedging and spot hedging, which are essentially transactions for price differences. Maybe when it comes to the concept, principle and details of hedging, many students who have just entered the field of quantitative trading are still not very clear. It doesn’t matter. Let’s use the “Analyze” tool provided by the FMZ Quant Trading platform to learn and master this knowledge easily.

In the Dashboard of FMZ Quant platform, click “Analyze” to jump to the tool’s page:

Here I upload the analysis file directly: This analysis document is an analysis of the process of opening and closing a futures-spot hedging position during the backtesting. The futures exchange is OKX futures, and the contract is a quarter contract. The spot exchange is OKX currency-currency transaction, and the trading pair is BTC_USDT. To analyze the operation process of the futures-spot hedging, you can see the following specific research environment file, written in two versions: a Python language version, a JavaScript language version.

You can see that the orders quarterId1 and spotId1 orders are fully filled, i.e. the hedging of open positions is completed.

Sleep(1000 * 60 * 60 * 24 * 7)       # Hold the position for a while and wait for the price difference to become smaller to close the position.

After the waiting time, prepare to close the position. Get the current ticker quarterTicker2, spotTicker2 and print them. The transaction direction of the futures exchange object is set to close the short position: exchanges[0].SetDirection("closesell") place an order to close the position. Print the details of the closing position order, showing that the closing order has been completed, the closing position finished.

By comparing the initial account with the current account, the profit and loss of the hedging operation is calculated.

In [17]:

diffBalance = nowSpotAcc.Balance - initSpotAcc.Balance
if nowQuarterAcc.Stocks - initQuarterAcc.Stocks > 0 :
    print("profits:", diffStocks * spotTicker2.Buy + diffBalance)
else :
    print("profits:", diffBalance - diffStocks * spotTicker2.Buy)

Out[17]: Profits: 18.72350977580652

Now let’s see why the hedging is profitable. We can see the chart drawn. The futures price is a blue line and the spot price is an orange line. Both prices are decreasing. The futures price is decreasing faster than the spot price.

In [18]:

xQuarter = [1, 2]
yQuarter = [quarterTicker1.Buy, quarterTicker2.Sell]

xSpot = [1, 2]
ySpot = [spotTicker1.Sell, spotTicker2.Buy]
plt.plot(xQuarter, yQuarter, linewidth=5)
plt.plot(xSpot, ySpot, linewidth=5)
plt.show()

Out[18]:

Let’s take a look at the change of the price difference. The price difference ranges from 284 at the time of hedging opening position (that is, futures go short, and spot go long) to 52 at the time of closing position (futures short position closed, spot long position closed). The price difference is from large to small.

In [19]:

xDiff = [1, 2]
yDiff = [quarterTicker1.Buy - spotTicker1.Sell, quarterTicker2.Sell - spotTicker2.Buy]
plt.plot(xDiff, yDiff, linewidth=5)
plt.show()

Out[19]:

For example, a1 is the futures price at time 1, and b1 is the spot price at time 1. A2 is the futures price at time 2, and b2 is the spot price at time 2. As long as the futures spot price difference at time 1 (a1-b1) is greater than the futures spot price difference at time 2 (a2-b2), a1 - a2>b1 - b2 can be introduced. There are three situations: (the quantity of futures and spot positions is the same)

a1 - a2 is greater than 0, b1 - b2 is greater than 0 a1 - a2 refers to the price difference of futures profits, and b1 - b2 refers to the price difference of spot losses (because the spot went long, the price of starting to buy is higher than the price of selling to close the position, so the money is lost), but the futures profits are greater than the spot losses. So it is profitable as a whole. This situation corresponds to the chart in step In [8].
a1 - a2 is greater than 0, b1 - b2 is less than 0 a1 - a2 is the price difference of futures profits, and b1 - b2 is the price difference of spot profits (b1 - b2 is less than 0, indicating that b2 is greater than b1, that is, the price of opening position and buying is low, and the price of selling and closing is high, so it is profitable).
a1 - a2 less than 0, b1 - b2 less than 0 a1 - a2 is the price difference of futures losses, and b1 - b2 is the price difference of spot profits. Since a1 - a2 > b1 - b2, the absolute value of a1 - a2 is less than the absolute value of b1 - b2, and the spot profits are greater than the futures losses. It is profitable as a whole.

There is no case where a1 - a2 is less than 0 and b1 - b2 is greater than 0, because a1 - a2 > b1 - b2 has been defined. Similarly, if a1 - a2 is equal to 0, since a1 - a2 > b1 - b2 is defined, b1 - b2 must be less than 0. Therefore, as long as the hedging method of short futures and long spot meets the conditions a1 - b1 > a2 - b2, the opening and closing position operations are profit hedging.

For example, the following model is one of the cases:

In [20]:

a1 = 10
b1 = 5
a2 = 11
b2 = 9

# a1 - b1 > a2 - b2 launches: a1 - a2 > b1 - b2

xA = [1, 2]
yA = [a1, a2]

xB = [1, 2]
yB = [b1, b2]
plt.plot(xA, yA, linewidth=5)
plt.plot(xB, yB, linewidth=5)
plt.show()
