To assist customers in reducing execution risk, TRADEX is now supporting VWAP orders for large cap stocks, which numbers approximately six hundred companies. 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 by 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. All TRADEX VWAP prices will be computed by Bloomberg and displayed by TRADEX after market close.
