Comparison is lacking functionality. Please add the ability to read the (date) values of the multiple tickers. For example I want to see what the price was on XYZ date. In addition, it would help if you can enable a line at 0% to see where the graphs cross from positive to negative.
Details: When I compare 2 or more tickers, I want to be able to read what the values of the compared tickers are at different time periods on the chart. Presently, I can only see it for the primary ticker, but not for the compared tickers. The best I can do is guess the gain or loss by the % legend on the right. This is a powerful tool that needs to be improved.
