In view of the fact that the hedging frequency of the futures and spots hedging strategy is not high, it is actually possible to operate manually. However, if you do it manually, it is very inconvenient to switch pages of various exchanges, observe prices, and calculate the difference, and sometimes you may want to see more varieties, and it is not necessary to set up several monitors to display the market. Is it possible to achieve this goal of manual operation with a semi-automatic strategy? It is better to have multi-species, oh! Yes, it is best to open and close positions with one-click. Oh! Yes, there is also a position display…
When there is a need, do it now!

Since the multi-species strategy is more suitable for IO design, a template class library named MultiSymbolCtrlLib is used in the code (encapsulation, calling the exchange interface through IO). Therefore, the strategy cannot be backtested, but it can be tested with the simulated bot (although the real bot has been run for 2 months, the test and familiarization stage is still run with the simulated bot).
Parameters
Before starting the test, let's talk about the parameter design first.
There are not many strategy parameters, the more important ones are:
- Hedging control table
LTC-USDT-211231|LTC_USDT,BTC-USDT-211231|BTC_USDT
Here is the setup strategy to monitor those combinations. For example, the above setup is to monitor the Litecoin contract (LTC-USDT-211231) of the future exchange and the Litecoin (LTC_USDT) of the spot exchange. A combination of future contract and spot trading pair are separated by | symbols to form a combination. Different combinations are separated by , symbols. 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 exchange, not defined by the FMZ platform.
For example, LTC-USDT-211231 is a second-quarter contract currently, called next_quarter on FMZ, and OKEX's interface system is called LTC-USDT-211231. For the Litecoin/USDT trading pair, the WexApp simulation bot is written as LTC_USDT. So how to fill in here depends on the name defined in the exchange.
- Hedging amount for interactive control hedging
Click the status bar control button to hedge the amount. The unit is the number of coins, and the strategy will be automatically converted into the number of contracts to place an order.
Other functions are to set the analog disk, reset the data, use the OKEX V5 interface (because it is also compatible with V3) and so on, which are not particularly important.
Testing
The first exchange object adds the futures exchange, and the second adds the spot exchange object.
Futures exchanges use OKX's V5 interface simulation bots, and spot exchanges use WexApp simulation bots.
Click the positive set button of the BTC combination and open the position.
Click to close the positive arbitrage then.
Lose!!! It seems that closing the position cannot cover the handling fee when the profit spread is small, it is necessary to calculate the handling fee, the approximate slippage, and plan the spread reasonably, and then close the position.
