GBN.V:$Gold Monthly
Another very long term chart is the variance of GBN.V's share price vs. the $U.S. gold price and the correlation with the ratio of GBN.V shares to long bond treasury prices and their correlation. What the gold price sell off in July has resulted in is a breakdown of the strong inverse correlation:

$Gold:$Silver Weekly
Another long term chart where I watch the correlation between the GBN.V share price and the gold/silver ratio is the weekly chart, where the correlation has zeroed out for a few weeks:

$ONE:GBN.V
Another chart with a different perspective is the inverse chart of GBN.V correlated with the gold/silver ratio and with the TLT. 'Buy points' can be determined through this method, although price is everything, since the shares are trading @ 1/2 cent.
