How can i create an indicator to draw gann's 9 point swing chart?

i cannot seem to save a variable form one period to the other.

Many Thanks,

  It helps to post an "non-code" description of what you are looking for.
 Sometimes I will give coding your request a shot (Wabbit is much better) but I doubt if
 I would if I have to search on the net for an exact definition of "Gann's 9 point swing"
 calculation.
 
 
 

Here you can find the explanation on the 9 point swing chart.

I would be able to solve it myself but I ran into this problem:
Let’s say you have an inside day ( inside() ) then you have to plot the indicator value of the previous day. This I can solve by ref to day -1 and -2 and calculating the value all over again.

But what happens if you have 10 consecutive inside days. You should either be able to save a value from one period to the next or to have a recursive formula.

Regards and thx for helping.

Judicious use of the ValueWhen() function can be used to look back to find the most recent occurrence that wasn't an inside bar.
