Dear mrtools!
You posted these incredible indicators, which are used in some strategies introduced on forex-station. Success rate is much higher, when three lines point up or downwards.

Is it possible to get an alert with wav-file, that can be chosen, when one, two or three lines (as option) change slope in the same direction. Maybe later also a % filter on calculation or adaptiveness or coloring of slope?
Thanks.
The mq4-file of mladen, changed by pacois is just for reference. The only states of 0 and 1 are difficult to use for one-time alerts.
