Quote Tracker has 4 different methods of generating pivot points and if you ever want to go absolutely bonkers - select them all.
The 4 methods are "Floor" so called because they were the first. "Woodies" and I haven't a clue who Woody was. Camarilla and this was invented by a bond trader, Nick Stott, back in the '89 and apparently a couple of sites have made a small fortune selling access to a calculator - hopefully a really small fortune ($189 a month - bet me). The last is the Demark pivots and I know of Tom Demark and have read several of his books and he is OK.
If you don't want to spend the 60 bucks a year for Quote Tracker there is an absolutely free calculator here that calculates all of the pivot points plus the fibbi lines.
I'm going to try the Camarilla method for a couple of days - I'll let you know what I think.
