Reading charts (bitcoinwisdom.com)

Hey all,

I've been lurking in the forum for a couple months, even registered a few weeks ago before I discovered I had to check the noob forum before posting. Questions for those of you who understand charts, trends, and fundamentals (I'm a noob, trying to learn; been teaching myself).

First, if there's any resource you would recommend checking to get a better grasp on the basics, I am open.

Second, when looking at the charts on bitcoinwisdom.com, does the number of future orders mean much? On the right, for the bids and asks, it seems to indicate how many potential orders at prices in increments. If asks outnumber bids (or vice versa) what does that mean? More pressure on the side with more orders?

Third, what other things should I look for on the charts, generally? As indications? Trends?

Thanks for any advice or recs. Doing my best to learn.
