Hello everyone,
I’m having trouble with an audible alert for the Squeeze indicator. I found an alert for the BBS squeeze indicator, the alert works…just not the way I would prefer it to. The actual signal is when the dot turns green at the close of the bar and the previous dot was red. Right now the alert sounds at every red dot and usually multiple times since the current dot may change from red to green over and over. So even if I can get it to alert going by the close it’s still going to alert at every red dot, when the signal for me is actually a green dot preceding a red dot. Somehow I need it to alert when a dot closes green and the previous dot was red. Is this possible? If somebody knows how this could possibly be implemented I would greatly greatly appreciate any help. Thanks in advance.http://i714.photobucket.com/albums/w...rFX/mt4pic.png
