I have had problems with TS, so again not necessarily defending, just the last couple days it has worked good here. During the minutes release it lagged a couple times for a second or two compared to trade platform, but otherwise it kept up. That has been unusual for me, as in the past on big reports, volume spikes it noticeably lagged for up to a minute at a time. I have 4 wksps open, 1 has a 1 min. chart of prem and 4 tick charts, 2nd has 4 tick charts, 3rd has a 1 min and 3 min chart, 4th has 1 and 3 min. charts with another 1 min of prem.. I also have numerous indicators on the charts(most of which I realized along time ago I don't even pay attention to, but leave on anyway).
I get it open from the time I hit enter from logon screen to all charts loaded in ~1 min 20 secs last time I checked. I have a P4 2.8Ghz with 1.5 Gig RAM, so nothing spectacular.
I would prefer CQG myself, but so far I can't say the data feed from TS has cost me the equivalent of the cost of CQG. SO FAR!
