Overlaid charts are charts that have two different datasets (i.e. a stock or an indicator), plotted on top of each other in the main charting window.
To learn about overlaid charts please refer to our easy-to-follow Step by Step Tutorial on Creating Overlaid Charts.
Please remember that there are limits on the number of datasets that each membership level can add to a single chart:
Free users can see up to 4, Basic and Extra members can see up to 6 datasets per chart and Pro can see up to 10.
