Now Plus Markets have launched their service I thought I would compare their prices against those on the London Stock Exchange. Cant see any compelling reasons (price or volume) for any broker to use Plus markets yet! It'll be interesting to see how it all unfolds. This snapshot was taken at 10.30am today from Plus Markets Top Gainers.

I've been a bit puzzled by the fact that my last two trades (AEP purchase on 11 March and AQP sale on 28 March) did not appear on the list of trades as shown on MoneyAM and Sharescope Pro. I have now realised this was because the trades were actually transacted (by different brokers) on Plus Markets rather than LSE.
This raises fundamental questions in my mind - I'm sure they must have been discussed in the past.
Are Plus Markets trades added to the official list of LSE trades later in the day after the market has closed?
If they are not added, and the volume for the day for a particular stock is LSE only volume, this has big implications for those of us who pretend to be technical analysts, and who like to use volume indicators such as On Balance Volume. The only meaningful volume for the day will be the total volume traded, rather than just the LSE volume.
Perhaps someone could enlighten me?

scallywag. Before Plus markets came along there were other 'exchanges' where trades appeared (virt-x) etc. Sadly there is no central reporting any more so you are right volume analysis is now going to be even more fragmented

Thanks Bullie. So you're saying that intraday trade volumes listed on platforms such as Sharescope, and cumulative end of day volumes from them and other data providers, are comprised of LSE trades only?
This raises another question - what are the relative proportions of Plus trades to LSE trades? I imagine that for the large caps, Plus makes up a relatively small percentage of total trades, and wouldn't interfere too much with volume based indicators. However, this may not always be the case.
Just for interest, I've added up the total trade volume for AQP on Plus Markets yesterday from the trade list on their web site - it comes to 48,336, as compared to the figure of 1.67 million LSE trades reported by MoneyAM and Sharescope. So Plus Market trades make up roughly 2.8% of the total of AQP trades yesterday. Not enough to cause a major error in volume analysis.....

Can we put orders in the market with Plus Markets like we do with SETS or is just market maker prices?

Howard: Just MM style
Scallywag, It is a small % but its building up

I think we have the same problem with the large cap stocks though due to trades going through Turquoise rather than the lse ?

I used to be able to make money just by implying predictive relationships of 'o' trades and 'at' trades on the big cap stocks. It's not been possible for the last 18 months as I simply don't see the 'o' trades being reported like they used to.

I seem to be increasingly using limit orders these days and not only are some executed via Plus but have just had one "Executed Off Market". What does that mean please?

I suppose as far as volume is concerned as long as it is as low as 2% it's hardly likely to be very significant.

Thanks for flagging it up though chaps, worth checking their site from time to time for individual shares volumes.

Stan it probably means your broker was already working an order in the opposite direction to yours so he simply matched them without routing through an exchange

CC - I don't think Turquoise are transacting yet, but existing trades are being routed through Plus, Virt-x, and Chi-X. I read that Chi-X accounts for 5% of the total trading volume transacted in the Eurozone and I got the impression some of London's business is going that way too. The US-based 'BATS' operation is planning to launch here as well - they are aggressive and likely to take business away from the existing operators by the sound of it.

It's all very well introducing competition to the exchanges, but it seems to me the result is rendering the LSE-based Level 2 and trade reporting obsolete. I can't understand why there isn't a regulatory need to have a unified platform, though I suppose a large attraction of Turquoise is the very fact that they aren't as transparent.

I guess traders can start to throw L2 in the bin within the next couple of years, unless something changes.

European Stock Exchanges: BATS Arrival on Foreign Shores Should Add Competitive Pressure on Equity Platforms

An FT article states that BATS will today announce plans to launch in Europe this autumn. Founded in 2006, the Kansas City, Missouri-based Better Alternative Trading System has quickly become the third-largest share trading market platform in U.S. equities. Last month, BATS handled about 1.1bn shares, or about 11.3% of all Nasdaq-listed stock volume and 8% of NYSE-listed shares.

1 BATS is an exchange operator with a proven ability to take on incumbent exchanges. We regard their decision to launch in Europe as confirmation of our thesis that LSE and Deutsche Boerses Xetra will suffer from stiff market competition and pressure to reduce trading fees.

2 BATS is very competitive on pricing. BATS gained significant market share in the U.S. on the back of an aggressive pricing policy (Exhibit 1).

In January 2007 they started offering heavy discounts on Nasdaq stocks to gain market share, even though this meant they were losing $5m in a month. BATS increased market share from 3% to double digits and managed to hold on to these gains after raising prices again.

1 When they started offering NYSE securities in February 2007 they managed to get 7% share in just 7 months once they introduced discounts in September 2007.

2 Randy Williams, vice-president for sales and communications, said: We are going to be just as aggressive in Europe as we have been in the US.

BATS is backed by brokers and high-frequency traders. BATS is backed by 11 investors, including Citibank, JPMorgan, Morgan Stanley, Merrill Lynch and Getco, a proprietary trading firm that is one of the largest market-makers in US equities.

1 Of the most often cited competitors to the European players (Chi-X, Turquoise and BATS), so far only Chi-X is fully operational. Chi-X launched last year in the European market, and has gained significant levels of market share, capturing as much as 10% of FTSE 100 trading and 7% of DAX 30 trading on some days. Project Turquoise has been delayed by a lack of a dedicated management team and discussions about the technology platform. These issues appear to be solved and launch is now expected for the middle of 2008.

On the question of volumes I notice today (so far) that there is twice the number of trades on Plus then there are on the main market for XUKS.

First time that I have noticed that there is any more then about 3-4% of volume in comparing the main and the Plus market (on a share that I am interested in), I wonder what it will be like at the close.
