do not carry comparisons from one tab to another, so we can plot different stock
It appears you are keeping the compares in the session cookie, so when going to another window or tab the comparison I did on one tab carry on over to new window or tab. WIthin the comparison, the stocks being compared become line style, and I cannot see the OHLC, Also, I may want to evaluate another stock or do another compare. So I would like you to not carry stock compares in one tab to another. I believe, it was long ago, but you can store the compare info not in the session cookie but separately. -- to reproduce chart on finance.yahoo.com/chart/AMZN on one tab then hit comparison and add more stocks to compare. then go to a new tab, voila, those compares are still part of the chart. They should not be, so that user can do more things in charts, else he is stuck with same compares polluting all charts. -- the compares even carry over to incognito session, I dont think they should unless user copies the URL with session cookie into the incognito or new tab or new window.
