Hi guys,

I have a very large data set, running well over 1,000,000 offset functions across the sheets. This as you can imagine is making the excel run very slowly.
I have seen index is an alternative to offset in some respects, however i am struggling to apply for my use.
I am currently using offset so that is can dynamically change the lookback period in a returns formula (I have uploaded a small segment from my file, see excel mini below).
I am hoping someone has an idea of how i can implement index or an alternative non volatile function in this respect?

Many thanks,
J

Excel Facts

Does the VLOOKUP table have to be sorted?
No! when you are using an exact match, the VLOOKUP table can be in any order. Best-selling items at the top is actually the best.

How about
Excel Formula:
=IFERROR(LN(D2/INDEX($D$1:$D$20,ROW(D2)+$M$1)),"")
