Foro sobre el comercio, los sistemas de comercio automatizado y la prueba de las estrategias de negociación

por favor ayudenme a poner flecha de compra y venta en este código.

Karputov Vladimir, 2015.11.09 13:36

Compruebe la carpeta "Proyectos" en MetaEditor.

P.D. Para la optimización es necesario limitar el número de barras para dibujar las flechas.

Pero no será hoy.

Adjuntar archivo de la versión "1.04".
