Amostras de código de plugins

Esta página fornece vários exemplos de código Python e C# para criar plugins nativos, incluindo ferramentas para negociação manual ou algorítmica no cTrader.

Repositórios de amostras de plugins

Amostras de código de plugins abrangentes, incluindo modelos prontos a executar para várias áreas e funcionalidades da interface do utilizador, estão disponíveis em repositórios separados Python e C# no GitHub.

Dica

Utilize parâmetros personalizáveis em plugins C# e Python para alcançar maior flexibilidade. Os parâmetros personalizáveis para plugins C# são declarados no código C# normal, enquanto os plugins Python requerem parâmetros personalizáveis declarados nos seus ficheiros .cs.
