I'm having trouble with P123 documentation

I am working on a custom series, trying to count stocks hitting new lows.

From somewhere, I got this rule:

UnivCnt("Low(0)=Lowest(#low,252,0)")

I think I know what it means in this case, but I want to understand it better. What if I want to find the number of stocks hitting new lows, but shift the entire window back one week or something? So I look it up in the online docs. The only thing I find is:

UnivCnt("criteria")
Count stocks that pass "criteria"

–which I already understood. I really want to understand “Lowest()”, but I do not see that in the online reference.

Can anyone point me to where to look? I’m sure there are any people who have used “Lowest()” before and can help in this case, but I’d like to be able to look this stuff up for myself for the next time I get stuck.

Is this a case where I am using some old function that has been replaced by a newer one, and the reason I don’t see documentation for it is because it’s deprecated?

Thanks.

‘Lowest’ was deprecated and replaced with ‘LowVal’ . This counts stocks making lows 5 trading days ago (1 week)

UnivCnt(“Low(5)= LowVal(252, 5, #low)”)

Excellent. Thanks Marco.
