I would like to no how I can sort for the biggest movers of the day? How can you write a PCF to find these? Do I just need to sort with price percent change today? I would like to no what a stocks range is on a daily chart? Like it open down $6.00 but closed up by $1.00. Can I find stocks like this?
How can I find these intraday?

It depends on what you see as "biggest movers". Sorting by Price Percent Change will tell you just that, the percent difference between the current price and the previous close. Many people would see this as fitting the definition.
Range is normally defined as the difference between the High and Low. Unlike Price Percent Change, this would not provide a price direction. One way to write this as a Personal Criteria Formula would be:
H - L
But this would probably be better at finding high prices stocks than symbols with large percent changes. Something like the following might be better:
High as Percent of Low:
100 * H / L
Another option would be to use True Range instead of Range. True Range is the largest of the High minus the Low, the High minus the previous Close or the previous Close minus the Low. One way to write this is:
(H - L + ABS(H - C1) + ABS(C1 - L)) / 2
Like Range, this would probably be better at finding high prices stocks than symbols with large percent changes. Something like the following might be better (a True Range version of the High as Percent of Low formula provided above):
100 * (C + H + ABS(C - H)) / (C + L - ABS(C - L))
You've also mentioned Open versus Close as a Range definition. We can simply subtract the values:
C - O
But you are probably better off with a Percent Change between the Open and Close:
100 * C / O - 100
If you download during the day, these PCFs will provide the intra-day values up until that point in the day. You may wish to review the following:
