If you use Yahoo! symbol then it is working fine.
It is not the problem of Stockalyze, if you go to finance.google.com and try to see yearly chart of RGD then you see exactly the same data as shown by Stockalyze. So, that means google doesn't have daily data of RGD after 16 June 2017. This is something we cannot do anything in Stockalyze.
I hope you are satisfied with the answer.
Thanks,
