Es un sencillisimo EA de media movil.
Se agradeceria una somera explicacion acerca de que hace cada codigo. Varios ya se de que van y como cambiar sus parametros, pero por ejemplo ese que pararia el abrir tantas ordenes seguidas no se donde esta ni como corregirlo o adaptarlo a mi gusto
El EA deberia abrir UNA UNICA operacion tan pronto como la vela abriera, segun la grafica en el que estemos, por encima o por debajo del SMA, y cerrarla cuando hubiera otro cruce. Y no abrir nueva operacion solo por que hace algunas velas que hubo un cruce: Solo con el primer cruce debe abrir.
En realidad me interesa el codigo que controla cuantas operaciones debe abrir y cuando debe abrirlas, y cuando debe cerrarlas y por qué.
el codigo fuente es este:
- Código: Seleccionar todo
