I normally scan the market updates on Briefing.com, on CNN and some other sites. What I'm interested in, is to find out what sites you prefer to scan before the market opens, in order to get as good a grip on what will happen during the day as possible, what the market thinks are the important resistance/support levels, what reports/economic data etc that may move the market during the day etc. There are free sites and those that cost to read. There are those that are written by people with great knowledge and have proved more valid than others. What's your experience - if you'd like to share it?
