# Help with indicator value on bar(j) not bar i=1

981

Hi Everyone,

Sorry for the subject but I am not sure how to express it correctly.

I wrote an indicator that right now can identify the High/Low (buffer name: Upper/Lower) of a given period, kind of Zigzag point.

The next step should be like that: At bar 1, analyze previous High/Low to identify what is the level of support and resistance.

(for example, resistence or level1[I]= average of most recent 2 High/Upper level)

That step is where the trouble is.

I cannot pull the value of the previous High/Low for analysis. I guess the reason is that the High/Low is not appear on bar[I] since I need to compare High/Low with bar on Left and bar on Right.

(I attached the indicator also)

Thank you so much.
