Volume is the quantity of trading activity. Generally, it is viewed from the sell-side. This aspect is connected to the transaction reporting obligation being on the part of the seller. Some observers consider NASDAQ activity as being double counted, whereas other do not. Here, market activity occurs with market makers. Often they will purchase a position for immediate resale to another buyer. Therefore, the 100 shares of stock will be viewed as a total volume of 200 shares. The first 100 is when the stock went into the market maker's inventory, and the second 100 is when it went into the (second) client's portfolio.
