This is how I figure the price of the ETF (GLD) in relation to Gold Futures.

Take the current price of Gold minus 7 percent. As I write today:

$1644/10 = 164.40

$164.40  - 7% = $152.89.

So when the Gold Futures chart is turning up or down,this where I go hunting for (GLD) strike prices.

Try and find this formula in a text book. Its only available here, at Marketforum $$$$$$$$

Spread the formula,not the virus!!
