GDX_GLD ratio trading

Here is a very simple system for trading GDX. Using a ratio and a 7/21 EMA on that ratio, we generate buy and sell signals....as you can see from the chart this has worked very well. You can follow the crossovers, but I like to take 1/2 off when I get a good grip....personal preference. E-mail me if you have any questions about this system.
