It is completely transplanted from the "CTP Commodity Futures Variety Moving Average Strategy". Since the Python version of the commodity futures strategy does not yet have a multi-variety strategy, the JavaScript version of the "CTP Commodity Futures Multi-Variable Moving Average Strategy" was ported. Providing some design ideas and examples of Python commodity futures multi-variety strategy. Regardless of the JavaScript version or the Python version, the strategy architecture design originates from the Commodity futures multi-varieties turtle strategy.
As the simplest strategy, the moving average strategy is very easy to learn, because the moving average strategy does not have any advanced algorithms and complex logic. The ideas are clear and easy, allowing beginners to focus more on the study of strategy design, and even remove the coding related part, leaving a multi-variety strategy framework that can be easily expanded into ATR, MACD, BOLL and other indicator strategies.

Backtest comparison
We compared the JavaScript version and Python version of the strategy with backtest.
- Python version backtest
We use a public server for backtest, and we can see that the backtest of the Python version is slightly faster.
- JavaScript version backtest
It can be seen that the backtest results are exactly the same. Interested friends can delve into the code, and there will be no small gains.
Expand
Let's make an extension demonstration and extend the chart function to the strategy, as shown in the figure:
Mainly increase the coding part:
- Add a member to the Manager class:
objChart - Add a method to the Manager class:
PlotRecords
Some other modifications are made around these two points. You can compare the differences between the two versions and learn the ideas of extended functions.
