Highest close? or highest value in series of x bars?

I can't seem to find a highest/lowest function that returns the highest value in a series of x bars.

Clearly HH & LL work for the highest high and lowest low of x bars, but I want to get the highest (and lowest) value of closing prices for the x bars.

Use MaxVal and MinVal with a Close series.

Great thanks jcl,

How do I exclude priceClose[0] and get the Maxval of priceClose[1] to [8].

Sorry, I'm used to metatrader, where you specify the bar you want to lookback from and the number of bars to lookback.

For excluding priceClose(0), add a 1-bar shift (+1). Series are explained here: http://manual.zorro-trader.com/series.htm
