I'm thinking that this shouldn't be so hard... but my experience with EasyLanguage was from 20 years ago, and I'm just getting back to it.

What I'm wanting to determine is the 52 week high. I know there is the ability to get the current 52 Week high, but I want to use it in a strategy and back test. So it needs to be a rolling 52 week high. HighY will only give me the high of that particular calendar year.

Any help?

Thanks in advance!!!!

If you are using daily bars, highest(high,252) will give you the highest high of the last 252 trading days (basically 1 year).

A bit more complex would be using an array holding the last 52 weeks. Whenever a new week begins, you'd replace the value from 52 weeks ago with the new value.
Then you can copy this array using Array_Copy and sort the copy with Array_Sort and get the highest high of the last 52 weeks.
