Re; Red delete button - can you undue?
Yes it is a delete button and I don't know of any way to recover the chart. If its a complicated and very important chart that can't be redone then I would send a very nice email to Stockcharts and see if they could possibly recover it from one of their backups.
If you have very important charts which can't be recreated then I would create bookmarks to the URL's for all of those charts, the bookmarks stored in your browser can be used to gain access to the chart again and then re-save it to your Fav List.
However there is another way to recover a chart if you've just accidentally deleted it. This may be a little different depending on your browser and version, but just use the back and forward buttons on your browser to navigate back to the page which had the chart on it. You may have to go back a page and then forward again before you see the chart. Then open that chart in another window or tab and then re-save it to your Fav List.
