Still doesn't explain what a vw trade is !! what does volume weighted average mean ???

jimmy
A weighted trade, where an institution tries to trade at the Voulme

jimmy b,

A volume weighted trade is where an institution tries to trade at the Voulme Weighted Average price at that time. On level 2 there is data known as the VWAP which is the volume weighted average price which in essence.

Ian

jimmy, the simple average price of trades of 10,000 at 10p, 1,000 at 11p, and 2,000 at 12p is

(10+11+12)/3 = 11p

whereas the volume weighted average price is

((10*10000)+(11*1000)+(12*2000))/(10000+1000+2000) = 10.38p

i.e. the average is weighted towards the larger trades.
