I prefer now log.scale. Now i have troubles to rewrite my trendline formulafor the log.scale.
As you see in the att.snapshot the lines are curved instead linear.
Firstly i have activated log.scale in the indicator builder.
I have tried something, but without the correct result.
I hope for help. In the zip file is the AFL
Here is the basic part from the formula:
/*SL = Support Line*/
PS = TroughBars(s1,per,1) == 0;
xb = LastValue(ValueWhen(PS,x,1));
xa = LastValue(ValueWhen(PS,x,2));
xab= xb-xa;/*x distance between a and b*/
//a is the start and b is the end of the support line
yb = LastValue(ValueWhen(PS,s1,1));
Ya = LastValue(ValueWhen(PS,s1,2));
ydSL = (yb-Ya)/xab;/*y(SL) daily change*/
SL = ydSL*(x-xa)+ya;
dRSL = ROC(SL,1); /* Roc SL (%)*/
