Admitting my ignorance also, but I think it means the close of trading is extended due to an anomaly in a trade, either due to the price being greater than an agreed percentage Buy or Sell. In other words a mistake or a agreed deal between seller and buyer, above any agreed volume.
Probably wrong but that is how it was explained to me by someone ages ago, so don't take it as fact.

This just gets worse and worse.
Does anyone know what it all means?
Will we put out of our misery tomorrow?
Why can't I pick less stressful stocks?
I need to lie down in a darkened room now.....

This is how the LSE explains the second one;
Notification to the market of an additional order entry period designed to reduce the likelihood of unrepresentative closing prices being generated.

Hi AdieH,
Yes, thats what I meant re above agreed volume.
It's likely to be a very large deal that is incorrect, that would falsely move the sp due to market re action. ( I think).
Could be a buy or sell.

I read that the perameters for this action are if the uncrossing trade would be more than 3% different to the closing price.
Still no wiser, but it sounds like one of 3 scenarios;
1) Someone on the keyboard is all thumbs
2) Huge buy or sell order that imabalances the auction
3) Some bugger has been caught with his hands in the till.
I'll go for 1)

My guess is that at such a low price, the absolute price movement breaches a pre-set percentage of the price.
Imagine SEO at the 50p party and it moves by - say - 5p at closing auction = 10%. That could be an "unrepresentative closing price".
Well at a price of 1.35p the absolute movement does not need to be very big - a .25p tick is 18.5% of the underlying price.
Not that I understand the closing auction at all, but I can understand the trigger mechanism here.
Funny really, I was thinking about building an extension with SEO profits. Guess I can do it now with SEO share certificates!

On the plus side, I was thinking how stupid I am.......but it turns out none of us know so I am in good company.
Now, what kind of fool would invest their money in a market situation without knowing how that market works?

Excuse me.
There is much negativity yet I am unaware of anything "official" that has changed the position.
Sure the cash limits are getting closer - but so is a conclusion of the Letters of Intent.
Nothing new here.
The only change is an increasing number of "I told you so" or "seen it all before" experts who appear to be spilling from other BBs. This is a strange obsession. I would have thought, accepting the truth of their self-proclaimed wisdom and success, they would prefer to be enjoying the fruits of their knowledge and success rather than spending days on end here.
Maybe the money their success made did not bring them happyness or the capacity to enjoy it!
Or am I missing something?

Well said Tony, if your not in SEO or have definatly made up your mind not to be in then why bother posting. The only long term person who saw this coming was blinger, like it or not.

Alan,
I must admit that after having one of those really lousy days, reading your third option bought the smile back...... Some bugger has been caught with his hands in the till.
I thought your second option more likely but it's not so humorous.
Cheers Greek.

A bit dated, but I think it explains the "price monitoring extension" quite well:

"LONDON (FTMW) - Ever wonder why London stocks stop trading at 4.30 p.m. but prices jump more than 5 minutes later? Go deeper
The reason is the use of a closing auction process at the end of the normal trading day.
The London Stock Exchange introduced the system in May 2000.
"It is generally seen as the most efficient way of discovering the closing price," the Stock Exchange's John Wallis told FTMarketWatch.
The process is in use across much of Europe. Indeed, the mathematical algorithm used in London to calculate the closing price is a European standardised one.
Auction nitty gritty
Throughout the regular 8 a.m. to 4.30 p.m. trading day there is automatic execution of trades in SETS stocks. SETS is the Stock Exchange Electronic Trading Service, otherwise known as the order book.
At 4.30 p.m., automatic execution finishes and the market moves into the auction period. The initial auction period runs for five minutes, during which time market participants can place both market and limit orders.
A market order is one without a specific price attached, which will be executed at the best prevailing price. A limit order is one that has a specific market price level attached to it.
A mathematical algorithm is used at the end of the 5-minute period to calculate a single closing price for the auction, calculated to be the price at which the greatest number of shares can be executed.
During the auction process an indicative closing price is displayed to allow market participants the opportunity to adjust their orders.
"Almost all the time, the auction process will be completed by 4.36 p.m.," said the Stock Exchange's Wallis.
Price monitoring extension period
However, there are two sets of circumstances under which the process can be extended by one, or if necessary two, 5-minute periods.
The first exception is a price-monitoring extension. If the closing algorithm calculates a price that is more than 5 percent away from the average price during the last 10 minutes of normal trading (4.20 to 4.30 p.m.), the auction process moves into a price-monitoring extension.
Much of the demand on a "normal" day for the closing auction will be from institutional participants, such as tracker funds that wish to execute market on close type orders.
The volume of participation by these players tends to be heaviest at the end of the month or quarter, and on the days in each quarter when the FTSE indices, such as the FTSE 100 [UK:1805550] are re-weighted.
If the demand to buy or sell at the close is sufficient to move the price outside the 5 percent band, then the price monitoring extension period allows time for liquidity providing or opportunistic market participants, such as market makers, to enter orders to balance the market.
When the auction process was introduced last May there was initially a single 5-minute price monitoring extension period, but a second period was introduced in November 2000 to allow the market more time to close if required.
Market-order extension period
The second type of additional auction period is a market-order extension. If at the end of the 5-minute auction period there are market orders left unfilled - i.e., orders that are to be executed at best price, but there is insufficient volume to completely execute them - then the auction process trips over into a market-order extension period.
In general, the occasions when there is a market-order extension coincide with days when there is a price monitoring extension.
And I used to think everyone stopped trading at 4.30 p.m.

I was/am curious as to why the two trading statements so close together:
17/08/06: Running out of cash; looking at options; 2 letters of intent which should lead to contracts.
08/09/06: Running out of cash; looking at options; contracts being finalised.
