Existe uma solução de muleta.

Use as variáveis globais do TERMINAL para criar seu próprio contador.

Basta pensar em um nome único para que duas janelas com o mesmo símbolo criem seu próprio

variável terminal global.

Adicionado

Se você não quiser abrir duas janelas de símbolos, você pode usar Magik como o nome da variável terminal global

você pode usar Magik

prostotrader:
Correto, se eu me enganei em algum lugar

A singularidade do nome está diretamente relacionada com o nome do símbolo, eu quis dizer o caso mais geral

IntegerToString(ChartID()) + ":" + symbol

ou seja, no seu caso (se todos os programas MQL no gráfico funcionarem somente com o símbolo atual)

IntegerToString(ChartID()) + ":" + Symbol()

em vez de

IntegerToString(ChartID())

não é um erro... apenas disciplina

Se você colocar 1 indicador e depois o segundo indicador, então

quando você remove o 1º indicador - o lixo total (Resultado 2), MAS

Se você colocar o 1º indicador primeiro e depois o 2º indicador e depois

remover 2º, depois 1º, tudo está bem (Resultado 1)!

Adicionado

Parece que se forem adicionados 2 indicadores, então ao remover o indicador que

foi colocada em primeiro lugar,

O OnDeinit(const int razão) é chamado tantas vezes quanto há indicadores no gráfico!
