Our system pulled 7,660.21 as the DJIA closing for yesterday. Yahoo finance shows the same, our competition shows the same. We have received a couple calls suggesting that the DJIA closed yesterday with 7659.97, the last caller has plans of reporting us to the AKC for listing an inaccurate number.
Yahoo, CNN, MSNBC, all agree with EE (i think they check EE before posting the close on their sites).
As far as i can tell, the number we posted with the DOW ending in 21 for this week is accurate.
