Our live Investing Matters Podcast Special which took place at the Master Investor Show discussing 'How undervalued is the UK stock market?', has just been released. Listen here.
Finally, I would also take issue with JazzzaGe's recent post that 41 has been achieved. No it hasn't - not until 41p is seen on the BID and surpassed. 41p has not been seen on the BID yet only on the OFFER - and it is the BID at which you sell and value your holding.
Usually a buy will be higher than mid and a sell will be lower - hence blue and red prints. A trade at mid price is printed green. However, buys can sometimes appear as sells (and vice versa) if buying is below mid price. When you can do this it often is likely the SP will retrace. So REDs v BLUES really is pure conjecture over the course of a session.

3v1 means that there are 3 market makers on the BID (ie they are looking to buy shares from sellers) and one on the OFFER (they are looking to sell shares).
If more MMs are looking to buy than sell then you can usually expect the price to tick up.
Depth is just the number of MMs trading the share and the 10000 is their usual market size
