Here is another article I found on scribd.com I thought it is worth reading. Hidden Divergence.

Just as classic divergence does not appear on every price chart, so it is with hidden divergence. But when they do appear, they are worthy of attention. The trick is to train your eye to recognize one when it presents itself.

Again, I am not the publisher of this article, but using the sharing functionality provided by scribd.com.

Enjoy!
