Resumo

Estratégia lógica

O núcleo desta estratégia é determinar se o preço está em uma tendência de alta ou baixa com base no indicador de tendência selecionado pelo usuário. A estratégia primeiro calcula mais de 20 médias móveis e linhas de regressão. Estes indicadores incluem os indicadores técnicos comuns na biblioteca padrão da linguagem de scripting Pine, bem como alguns indicadores personalizados escritos pela comunidade de codificadores Pine. A estratégia então consulta o valor atual de um indicador selecionado e o compara ao valor anterior. Se o valor atual for maior que o valor anterior, a tendência é alta. Se o valor atual for menor que o valor anterior, a tendência é baixa. Finalmente, a estratégia determina se deve entrar em uma posição longa com base na direção da tendência.
