Thank You for idea.
1.This code plot lines correctly but dissapears on chart in weekends
dates.
2.Plot do not extend to dates beyond last bar.
3.Description is like F2(29)=0 not date ;Is this possible to convert
output of DaysSince1900() to Date format.
Shortly...
The idea of Carolan spiral looking for "window" in the future .
Window is two or more dates close to each other from 2 or 3 spirals.

Because my code shows a lot of extra's that have nothing to do with
the actual problem. I just took something that used future
simulation ... You will understand immed how it works. Just clicking
in the future gives you a random idea of the trend ...
