Can’t agree with you, Prague. You’re quite right to point out that a significant proportion of investors who make up market depth – in effect – ‘don’t count’. I regard them as ‘constants’ (in a mathematical sense) in the depth-pile. The active players in the market bounce around in the top five to ten levels actively changing, therefore, the depth numbers. Allowing for some of the fake bids you mentioned (of which, incidentally, I don’t think that there are enough to engage in wholesale depth manipulation), monitoring market depth makes up half of my trading activity.

I NEVER trade without checking out the numbers. They are as vital - and reliable – a tool as chart analysis itself.
