You have opened a new world for me @float with your suggestion to look at tradingview. I am impressed with the easy-to-use scripting. Below, the heavy blue line charts the progress of RSG with the orange line overlay depicting the All Ords. And the lighter blue line chart below that is the (scripted) relative price of RSG with respect to the All Ords. As you say @float, in the case of the gold stock RSG, I can devise a chart of the relative price with respect to some appropriate gold index. Thank you very much for your help. Cheers, JoMo.
