Another Pivot Point Question

At what time of the day do the new pivot points start EST? I have got a pivot point indicator attached to my charts and it works great except I am a little confused onto when exactly the new pivot points start? The indicator allows me to change what time I want it to calculate the next day, I am just unsure when that is?

It is a little bit of whatever suits you, I know many different traders who use pivots, in all different timezone, and many of them use many different starting points. Probably the most common is to use EST or GMT, personally I view the real day to begin at the open of Europe.

If you are trading the forex, numerous traders use the midnight to midnight Eastern time.
