volume question


Hi,

could somebody please explain the volume shown on the mypivots summary? It differs a lot from the volume reported by cme [url]http://www.cmegroup.com/daily_bulletin/preliminary_voi/VOIREPORT.pdf[/url] or [url]http://quotes.ino.com/chart/?s=CME_ES.U09.E&v=w&w=1&t=f&a=2[/url]
These are 1.410.004, mypivots is 2.278.262!
