If we understand the process of bringing the information to your screen and the accuracies; then we can be better served to invest. The problem is the reporting system at the exchanges. It is based on brokers' reporting their transactions. I found that out at a local office, many years ago. You report to the headquarters first, then to the exchanges. So DLJ may have a different volume and price transaction on their screen, than Yahoo or Quote.com, etc. On the other hand, Quotron reports the data from the specialist on the floor or market makers from the Nasdaq system. But, NYSE reports are only 11% of the total stocks traded, until brokers report in the rest of the 89%. Two sets of data? No, many more than that at each large brokers' trading desks. Their own reports from branches, plus Quotron, plus workstation info from exchange systems; which accounts for more than six computers on their desks. They have to know Quotron because customers have that data. But for small investors, we can only discuss what is available free on the internet. Such is Yahoo's charts.
