This looks like a great idea. I accept your help with great pleasure, because I am somewhat overwhelmed.
In the attached file, you will have two sets of thee colums. These are the results of either IWM/GDX or TWM/GDX combined portfolio (compared to each element separately).
I'd be happy if you could share the formula that you use to calculate the drawdowns that you mention on these equity curves. I can then generate different ratio of IWM/GDX combinations as I only use now 50/50.
Thanks again for your help.
