People, unless they are naturally well disciplined, are extremely open to suggestion. Folks like to be given, tips, listen to the news stories, seek out rumours in internet chat rooms, or maybe subscribe to secret information leaked from unknown sources.
For the most part, professional traders, syndicate traders, and the specialists, do not look at these things. They simply do not have the time. Professionals have to act swiftly, as soon as market conditions change, because they are up against other professionals who will act immediately against their interests if they are too slow in reacting to the market. The only way they can respond that fast is to understand and react, almost instinctively, to what the market is telling them. They read the market through volume and its relationship to price action. - Tom Williams
