this was the online calculator that i use to use, see if it will take care of what you need, http://www.mypivots.com/calculators/pivot-point-calculator.aspx if you need other tools like a currency correlation w/market or different types of pivot calculations, etc try this link; http://www.mataf.net/en/forex/trading/correlation/currency/
I have it as pivot + range, but it seems that some others' might be a bit different than mine. Mypivots do seem to have the same calculations I use.
