Please may someone assist me with the indicator attached, it has a SERIOUS BUG issue in the sense that when I load it, and activate the template (attached as well) MT4 ALWAYS freezes and then eventually disconnects automatically, ALL THE TIME. It even gets worse to an extent that after disconnecting a number of times mt4 ends up not loading anymore, UNTIL I remove the indicator. Please I WILL NEED A DEMO (FOR A DAY)
