The Hotlist feature in WealthCharts allows you to analyze which stocks fall within the top 10 based on various metrics that are available: for example, best percent gainers/losers on a 52-week basis, highest volume, largest opening gaps, etc.
The symbol list and metric that is being analyzed can be determined using the two dropdowns at the top of the Hotlist window – the first one allows you to select a segment of the data that will be looked at, and the second one for the metric which will serve as the basis for the top 10 rankings.
