"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken

You seem to provide more data for a stock via TCP/IP Historical (thanks!). 2. Volumes (and some prices) provided for TCP/IP Historical is always different between the two servers. Not by much, but a couple of thousand shares. Here is Microsoft 60 minute data from the new servers: 2007-06-07 07:00:00,30.1600,30.1600,30.1600,30.1600,100,100; 2007-06-07 09:00:00,30.2800,30.2100,30.2100,30.2700,16850,16750; 2007-06-07 10:00:00,30.2900,30.0000,30.2600,30.2100,9005266,8988416; 2007-06-07 11:00:00,30.2200,30.0400,30.2000,30.1300,17956795,8951829; 2007-06-07 12:00:00,30.1700,30.0500,30.1300,30.1300,23974269,6016474; 2007-06-07 13:00:00,30.1800,29.9400,30.1300,30.0300,31509952,7535683; 2007-06-07 14:00:00,30.0700,29.6600,30.0300,29.7673,43974765,12446653; 2007-06-07 15:00:00,29.8600,29.7200,29.7700,29.7800,52299461,8324696; 2007-06-07 16:00:00,29.7900,29.7500,29.7800,29.7600,52760660,461199; Here is from the old servers: 2007-06-07 10:00:00,30.2900,30.0000,30.0200,30.2100,9005366,7452192; 2007-06-07 11:00:00,30.2200,30.0400,30.2000,30.1300,17956795,8951629; 2007-06-07 12:00:00,30.1700,30.0500,30.1300,30.1300,23984769,5857759; 2007-06-07 13:00:00,30.1800,29.9400,30.1300,30.0300,31523752,7038683; 2007-06-07 14:00:00,30.0700,29.6600,30.0300,29.7673,43980765,11451845; 2007-06-07 15:00:00,29.8600,29.7200,29.7700,29.7800,52307661,8276267; 2007-06-07 16:00:00,29.9100,29.5900,29.7800,29.6000,68184946,15820585; 2007-06-07 17:00:00,29.6200,29.6000,29.6000,29.6200,69439784,1239338; Are they using the same datasource?
