why are all the volumes different?

Quote from m mother:

so i was looking at pslv on google, yahoo and schwab's pages and all of them show different volumes for today. anyone have any idea why that'd be? currently the 3 show me:

http://www.google.com/finance?q=pslv&ei=azT4ULCBJMziqAGgBw 123,321 contracts

http://finance.yahoo.com/q?s=pslv&ql=1
580,246 contracts

and schwab shows 630,149

i'm confused~*~

...m =mother;, i changed your name from dumb mother to m- mother,LOL.
Best answer is focus on a few.You may be suprised @ how good you get at guessing.

Not a prediction;
barchart.com has average volume
of PSLV as 948,000+

ibd.com has average daily volume as 1,500,000+;;volume is trending up.If you dont like the trend in silver... wait a bit ;;its changes.
investors.com , barchart.com are for people not ''dumb'' Hope this helps, it helps me .With all due respect,, paying for data may not insure its accuracy

You may want to focus on a few + record data yourself; you may be suprised how good you get @ guessing price + volume over the years.

Wisdom is profitable to direct.:cool:
