Il est complètement transplanté du CTP Stratégie de moyenne mobile des contrats à terme sur matières premières. Puisque la version Python de la stratégie des contrats à terme sur matières premières n'a pas encore de stratégie multi-variété, la version JavaScript de la stratégie CTP Commodity Futures Multi-Variable Moving Average a été portée. Fournissant quelques idées de conception et exemples de stratégie multi-variété sur les contrats à terme sur matières premières Python.Stratégie de la tortue sur les contrats à terme sur matières premières à multiples variétés.

En tant que stratégie la plus simple, la stratégie de moyenne mobile est très facile à apprendre, car la stratégie de moyenne mobile n'a pas d'algorithmes avancés et de logique complexe. Les idées sont claires et faciles, permettant aux débutants de se concentrer davantage sur l'étude de la conception de la stratégie, et même de supprimer la partie liée au codage, laissant un cadre de stratégie multi-variété qui peut être facilement étendu en ATR, MACD, BOLL et autres stratégies d'indicateurs.

Comparaison avec les tests antérieurs

Nous avons comparé la version JavaScript et la version Python de la stratégie avec backtest.

  • Backtest de la version Python

Nous utilisons un serveur public pour le backtest, et nous pouvons voir que le backtest de la version Python est légèrement plus rapide.

img

  • Test de retour de la version JavaScript

img

On peut voir que les résultats des backtests sont exactement les mêmes.

Élargir

Faisons une démonstration d'extension et étendons la fonction graphique à la stratégie, comme indiqué sur la figure:

img

Principalement augmenter la partie de codage:

  • Ajouter un membre à la classe Manager:objChart
  • Ajouter une méthode à la classe Manager:PlotRecords

Vous pouvez comparer les différences entre les deux versions et apprendre les idées des fonctions étendues.
