As was pointed out to me yesterday. Stockcharts.com uses
after hours quotes to update their close. So from 4:00 til
4:15 you'll see the "close" moving around. They're not a
reliable source for the SPY System needs. Using CNBC, Yahoo,
etc. would be better.
Perhaps as a group we should start tracking the reliability of
different data sources.
I have been comparing the closing prices right at 4:00pmEST and
it seems CNBC has it right. When you compare what CNBC shows
right at closing with other quote systems after their dust settles
around 4:15pmEST or even later they then show what CNBC showed
right at 4:00pmEST.
