From time to time the connection to RealTick is getting harder. If you like to log in the weekend, it's for some reason been down. How often is it? Cheers.
I usually don't have a problem, though sometimes early weekend morning it will be down for a few hours...but not very often. I seem to remember getting an email from TNT about RT being down for a substantial time this weekend due to server maintenance...I looked for it but already deleted it. But, in general, no real downtime...hope this helps.
