I feel extraordinarily foolish, after having said good things about qcharts, and then noticed something very disturbing today. I was discussing the DIA's with a fellow trader. I keep a daily, weekly, 60, 15, 5, and 2 minute chart linked. The daily chart shows an opening price of 78.48 (and I crosschecked against a quote from moneycentral.com). But, the 5, 15, and 60 all showed the opening of their first candles as 77.69. And yes, all my charts have the 'all sessions' box unchecked, so no pre or post market data is showed. I just noticed this, and havn't looked at other charts yet, but is this typical. I mean, really, I rather have the servers go down than have this kind of problem. I wonder how many trades that went sour weren't even my fault. Anyone have similar experiences or can shed light on what's going on?
