The VWAP for a stock is calculated by adding the dollars traded for every
transaction in that stock ("price" x "number of
shares traded") and dividing the total shares traded. A VWAP is computed
from the Open of the market to the market Close, AND is
calculated by Volume weighting all transactions during this time period
