Sure, I understand that. What I meant was that if we, for example, look
at the first company traded on OFEX:

http://www.ofex.com/data.shtml?ISIN=GB0034318898

We see that the last trades are (as I write this) :

Trade Date  Trade Time   Price Volume  Type Consideration
  10/01/2006    10:07:34   1.50     100,000    O   1,500.00
  03/01/2006    13:10:34   1.25     147,059    O   1,838.23
  24/11/2005    11:26:20   2.25     220,000    O   4,950.00
  11/11/2005    13:06:07   1.50     10    O   0.15
  31/10/2005    10:40:08   1.25     24,000    O   300.00

However, from what's been posted here, far more trades may well have
occurred, but these are the only ones that were reported to the
exchange. And as it happens for this equity, we can see that the price
is still the same as that of the last trade, two days ago.

Also, it appears that someone saw fit to report 15 pences worth of
trading to the exchange last november. I would guess that this is
because they did it through a broker, and the broker reports all trades
to the exchange as a matter of course?

Cheers,
