Cryptocurrency Manual Futures & Spot Hedge Strategy

In view of the fact that the hedging frequency of the current hedge strategy is not particularly high, it can actually be operated manually. However, if you do it manually, switch pages of various platforms, observe prices, and calculate the price spreads, which is very inconvenient. Sometimes, you may want to see more symbols, and it is not necessary to set up several displays to show the market quotes. Is it possible to achieve this requirement of manual operation with a semi-automatic strategy? And it is better to have more symbols? oh! Yes. It is best to open and close positions with one click. Oh, right. There is also a position display...

If there is a need, do it now!

Since the multi-symbol strategy is more suitable for IO design, a template library named MultiSymbolCtrlLib is used in the code (encapsulated and calling the exchange interface through IO). Therefore, the strategy cannot be backtested, but it can be tested with the simulated bot (although it has been run in a real bot for 2 months, in the stage of test and familiarization, you'd better run it in the simulated bot).

Parameter

Before test, let's talk about the parameter design.

The strategy parameters are not too many, and the important ones are:

            
            
            
LTC-USDT-211231|LTC_USDT,BTC-USDT-211231|BTC_USDT

Here is to set the strategy to monitor those combinations. For example, the above setting is to monitor the Litecoin contract (LTC-USDT-211231) of the futures platform and the Litecoin (LTC_USDT) of the spot platform. A combined futures contract and spot trading pair are split by | symbol to form a combination. Different combinations are split by , symbol. Note that the symbols here are all in the state of the English input method!
Then you may ask me how to find the contract code. These contract codes and spot trading pairs are all defined by the platform, not defined on the FMZ platform.
For example, the contract LTC-USDT-211231 is currently a next-quarter contract, called next_quarter on FMZ, and OKEX interface system is called LTC-USDT-211231 . For the LTC/USDT trading pair, the WexApp simulated bot is written as LTC_USDT. So how to fill in here depends on the name defined in the specific platform.

• Hedging amount of interactive controls
  Click the control button in the status bar, namely the hedging amount. The unit is currency amount, which will be automatically converted into the contract amount by the strategy to place orders.

  

The other functions are to set the simulated bot, reset the data, use OKEX V5 interface (because it is also compatible with V3) and other functions, which are not particularly important.

Test

The first added exchange object selects the platform adding futures, and the second one selects the spot exchange object.

Futures platforms use OKEX V5 interface simulated bot, and spot platforms use wexApp simulated bot.

I clicked the positive arbitrage button of BTC combination and opened the position.

Then, click the positive arbitrage to close positions.

loss! ! ! It seems that when the profit spread is small, closing the position cannot cover the fee. It is necessary to calculate the fee and the approximate slippoint, and then reasonably plan the spread for closing the position, and then close the position.
