After Trading for several years now using TA and watching T&S all the time I have the feel for the price-action. I'm not a programmer so that's why I haven't tried the following idea. How about adding all the volume that is traded at Offer and adding all the volume that is traded at Bid for a certain amount of time (i.e. since the bottom of a trend - the starting point should be defined as soon the market is in a trend) This could give an additional information about the balance of power.. wouldn't it? Is someone already doing that or has experience with something similar?
