I've found an interesting article about volumes:
PART ONE
I use a lot of different indicators and methods, but the one that has shown me consistent success is price and volume at support and resistance. Support or resistance areas come at previous highs and lows (that is why stock and indexes develop trading ranges, they bounce off previous highs and lows). I will show you how price and volume react to previous highs and lows and why price pushes through or reverses at these points.
Previous highs and lows in a stock or Index define current support and resistance areas. A Previous high or low in a stock or index is called a swing. I draw a horizontal trend line from the previous swing high or low to see at what price support or resistance will come in at in the future. These previous swing highs and lows are places where decisions are to be made for buy or sell orders. The horizontal lines drawn from previous highs and lows indicate where the support or resistance may come in the future.
Sometimes a picture is worth 1000 words. The Line graph of a stock or index below illustrates what a swing high and low are.

The following rules I have developed with price and volume came in part with studying the works of the master of price and volume, Richard Wyckoff. Mr. Wyckoff developed techniques in the 1930's that combine price and volume of equities that had price predictability. The techniques he developed stood the test of time and still work to this day. I have expanded on these ideas and came up with the following rules that I use daily in my trading. In order to keep this article brief, I will not go into all of the rules, but here are some that we can go over. Here we will view a price history to see where buy and sell signals developed.
Rules that I follow using price and volume to determine buy and sell signals on the Nasdaq composite and the NYSE indexes
1. Test of a previous high or low on 8% or greater decrease in volume and closes back below the previous high (or above previous low) imply a reversal. The market needs to break the previous high or low and then close back into the trading range to prove the point.

2. Test of a previous high or low on 3% or less in volume shrinkage, imply that high or low will be exceeded.

3. Always compare volume relationship to first high or low; even on 3rd and 4th re-test. The volume buy and sell signal relationship stay the same.
