I truly believe that by combining
Volume
Spread
Analysis with Market Profile/Auction Market Theory one can create a powerful way to view, understand and trade the markets.
All markets are governed by the laws of Supply and Demand. Specifically, the imbalances of supply and demand brought about by Professional (or Smart Money) traders.
The place to begin is with the book,
Master the Markets by Tom Williams. Currently it is only available at Tradeguider.com. They have told me that they are looking for a publisher for wide spread (no pun intended) distribution. Personally, I do not like the tradeguider software and that is ultimately what they are about. However they do offer a lot of free information on
VSA.
Tom Williams took the Wyckoff (concepts) course and expanded on the concepts. Wyckoff looks at price and volume. Tom looks at volume, spread (range of bar) and closing price.
Friday morning 0815 EST they are running a public demo. Go to the web site and click on enter site, if you are interested. Tomorrow (3/9) will be interesting as it is a big "news day". Professional money uses news driven events to manipulate the market. There should be ample opportunities to see them in action. Of course, many of you will be trading the event yourselves, but if not check it out.
On the site there are a number of webinars that can be viewed for free. There are also some webinars on the CBOT site.
