Acrescentarei outra função ao Expert Advisor

às vezes é necessário não acionar imediatamente a linha, mas quando ela tiver cruzado e fixado a barra

meio que enganado -

da linha de tendência - se ela cruzar e a barra permanecer lá, o sinal irá disparar

input string   t10="----- Trend Line Name ------";      // Trend Line Name
input string   InpNameAverage          = "AVERAGE 0";   // Trend Line Name Средняя
//---

outro indicador enganou - linha horizontal superior e inferior, linha de tendência média

versão de demonstração - como funciona em combinação com este indicador

Se a linha verde fosse junto com a azul, não haveria problema.

outra versão para o teste

há agora três linhas de tendência no indicador e o Expert Advisor abre uma posição a partir delas

input string   t10="----- Trend Line Name ------";      // Trend Line Name
input string   InpNameAverage          = "AVERAGE 0";   // Trend Line Name
input string   InpNameAverage0         = "TOP 0";       // Trend Line Name
input string   InpNameAverage1         = "LOWER 0";     // Trend Line Name

outra versão para o teste

Agora há três linhas de tendência no indicador e o Expert Advisor abre posições a partir delas

Aqui está uma versão - como eu fiz - está funcionando totalmente a partir das linhas de tendência que você desenhou manualmente

as configurações - que possui
