Let me know if there are other indicator scripts you would like to see me publish or if you want something custom done!
The reason must be on the line 43 of the script. The phase must be in degrees. phase = i1 != 0 ? 180/pi * atan(q1 / i1) : 0
For me the best indication of a sure change in trend is when the FAMA line changes direction, up or down.
I like to fill the space between the lines of green when MAMA>FAMA and of red if not.
