[EquisMetaStock Group] Error TrendLine.txt?

[Menalbi <menalbi@xxxxxxxxx>]

Hi,

I did something wrong or the formula really has some 
mistake, and we have been mistaken, think it are in 
this part:

price1:=PR; 
price2:=PR; 

Because when it chooses the second option in the 
variable "display" "Trend points=2"

display:=Input("plot Trend line = 1, Trend points = 
2,1,2,1"); 

The return indicator ZERO.

Alberto.
