Alan, you're right about each buy being a sell and vice-versa, but it's even more complicated than that: When you sell, a market maker buys. He/she then sells to another buyer at the same or different price. For this reason, the volume you see on NASDAQ is twice the corresponding volume on NYSE. You'll see the same trade posted twice. You can imply a buy or sell based upon the direction of the price changes and volume, and by comparing the trade price to the previous Bid and Ask prices. For example: TRADES BID ASK 5000 @ 10 1/8 10 10 1/8 10 10 1/16 1000 @ 10 1/16 3000 @ 10 1/16 500 @ 10 9 15/16 10 With a pattern like the above, you can safely conclude the 500@10, 4000@10 1/16, and 5000@10 1/8 are all "buys". The trader is paying the ASK price.
