There's no question that the one source that drives a stock's price more than any other is news. A piece of news can turn a bullish stock around quicker than anything. Regardless of any good fundamental or technical analysis, news is the king. Changing news has wrecked more trades than Elizabeth Taylor has wrecked marriages.

The news roundup portion of Real Time Markets is designed to help prevent a trader from getting zapped by unexpected news. The news roundup is an aspect of the tool that should help keep you safe from the swirling winds of news that can assail the stock market.

Assorted vendors provide news that is constantly flowing throughout the day. The news is sorted by the individual stocks (which are presented by symbols, in alphabetical order) and stamped with the time it comes through the system. News comes from sources like the PR Newswire, Zacks, Comtex, BusinessWire, Track Notes, and Real Trader. Any of the sources can be halted with the click of a mouse, and then added back with the same degree of simplicity.

News can be filtered to show what has happened during the current market day or the previous day. It can be filtered by vendor, as well. News for individual stocks can be seen simply by accessing "Today's News" and typing in the symbol code.

Items that appear through the news roundup tool can have a bearing on how the stock performs. If the stock lands a big government contract, that piece of good news could have a potentially bullish effect on the stock. A pharmaceutical stock that has its patent request turned down by the federal government is liable to lose big on that news. The main thing a trader must do is avoid being surprised by a news announcement. That's where the news roundup portion of Real Time Markets comes in very handy. It can save you money.
