death by charts, page-55

Thanks again bungi2. Love to see long term charts on market depth and how it correlates with the movement of share prices. It is more interesting for a group of shares say explorers or miners than individual companies. One could assume that if the majority of shares exceed 1.0 as is the case in this chart then the market as a whole would be moving up. What if the average were 1.2 or 1.5 or say 2.0?
What could one expect the shares to do on average? What would be the average percentage increase?
