Can't quite figure this one out. I know the highest High Value function will calculate the highest value over a number of periods including today (e.g. hhv(close,5) will calculate the Highest Close over the preceding 5 periods). What I'm trying to obtain is the Highest High Value over a number of periods x days ago , for example the 5 periods preceding say, June 1st. The last date in the comparison would then be June 1st and the first date in the comparison would be 5 periods prior. I'm sure it's not that difficult but I'm racking my brain here. Many Thanks
