3The Chart Scanner is the first step of a day trade. It reads thousands of
4free charts and lists the ones that match a rule. That is all it does. A scan
5is a list of charts that match a rule, not a list of stocks to buy, and a
6setup on a chart is not a prediction. Most people who day trade lose money;
7the scanner does not change that. It only saves you from flipping through
85,000 charts by hand.
