Indicadores: Custom Moving Average Input Color
É possível escrever um utilitário que altere qualquer linha/histograma (etc.) de um indicador arbitrário de acordo com o princípio mostrado no vídeo.
Bom trabalho! Obrigado!
I adapted the code to include the lineweight and style settings:

E poderíamos adicionar a possibilidade de modificar a espessura da linha do EA?
E como ele é modificado em relação ao código do EA?
