Help required to create lines from opening range

[Catgut]

I'm an absolute beginner so need a little slack if too slow.

Have been using Alexs Hi/Lo range lines based on X Minutes.

How do I create 2 extra lines one above and one below this range.

If for example i am looking at prices for the first hour and the price difference is eg 24 points say -open price 50, and at 60 mins 26 (50-26=24).

I would like lines corresponding to this diffence eg a line at 74 and a line at 2 (26-24).

Many thanks

I'll ask it another way

Can someone help me with a formula which calculates the difference between 2 prices (the hi and lo of the first hour)


Based on this difference =x how do you draw lines at high +x
and also at lo -x.

Any input appreciated
