Python version de la stratégie de la commission de l'iceberg

Cet article présente deux stratégies classiques pour la transplantation: la commission Iceberg (achat/vente).https://www.fmz.com/square/s:Iceberg/1

Citant la version JavaScript de l'introduction à la stratégie de trading de commission Iceberg:

La commission Iceberg fait référence au fait que lorsque les investisseurs effectuent des transactions de grande valeur, afin d'éviter un impact excessif sur le marché, la commission de la commande importante est automatiquement divisée en plusieurs commissions, en fonction du dernier prix d'achat / vente 1 actuel et du prix fixé par le commerçant.

Beaucoup de pages de trading d'échange sont livrées avec des outils de mise en service d'iceberg, qui ont des fonctions riches, mais si vous souhaitez personnaliser certaines fonctions ou modifier certaines fonctions en fonction de vos propres besoins, vous avez besoin d'un outil plus flexible. La plateforme FMZ est conçue pour résoudre ce problème correctement. Notre stratégie square n'a pas trop de stratégies de trading Python. Certains traders qui veulent utiliser le langage Python pour écrire des outils et des stratégies de trading doivent se référer à des exemples. Par conséquent, la stratégie de mise en service d'iceberg classique a été portée sur la version Python.

La stratégie logique n'est pas compliquée. Lorsque la stratégie est exécutée, elle va dynamiquement placer et annuler des ordres basés sur les paramètres de la stratégie et le prix du marché actuel. Lorsque le montant de la transaction / numéro de pièce atteint ou s'approche du numéro de paramètre, la stratégie s'arrête. Le code de la stratégie est très simple et adapté pour les débutants. Les lecteurs intéressés peuvent le modifier et concevoir une stratégie qui convient à leur style de trading.
