When you are in the StockCharts.com site and you request a symbol that is not in their system the page that opens is the Site Search page. On that page there is a link to "Request a Symbol".
StockCharts is a site focused on Technical Chart Analysis and thus they do not cover every stock in the universe. Here's a quote from their website covering this subject.
We have to remember there is a cost to purchase this data for redistribution and maintain it. It would be unfair to pass that cost on to all members when only a very few are following a particular stock and really none of StockCharts analysis tools are applicable in most of these cases.
However if you still feel some of your stocks in question meet the criteria, send them a request and justify your position as to why you think it is worth the cost for everyone.
