What was the genesis of Chi-X?
In some ways, Chi-X has been many years in the making. A lot of people involved in Chi-x have been in the industry for a long time, looking at how we can conduct equity trading in a faster, cheaper and smarter fashion. But Chi-X is also a child of the regulatory changes that MiFID is unleashing. The genesis of Chi-X is the coming together of four elements: the connectivity options within Europe; the technology of the fourth-generation trading systems; the regulatory environment; and of course growth in market demand for electronic and, more recently, algorithmic trading and DMA access. If you put together the changes in regulation, technology and client demand, you've got a product. Chi-X is not the only answer by any means, but it is a credible and so far successful attempt to deal with the challenges the industry is currently facing.
From your launch announcement in September 2006, Chi-X has
accelerated to a published share volume of 367m in September
2007. Are you surprised at the level of success so far?
We're pleased to be in a strong competitive position. First mover
advantage in the financial markets can be important, but I'm not
surprised because I know the complexity of the work needed to get
us to where we are today. Some of that work was relatively
straightforward and some was among the hardest I've ever done.
We've found one solution to the equation, but there are many
potential solutions and I'm sure we'll have more competition.
Over the years many have tried and many have struggled to gain traction and attract liquidity (such as Tradepoint, and the LSE's Dutch trading system). Before launching Chi-X, we spent some time considering why this has been the case and have taken the considerations into account. For example, not only is Chi-X a low cost, high speed alternative, but it introduces an attractive pricing model and open access via FiX connectivity protocols. Some are surprised that we're showing modest but vital signs of life as every single attempt until now has failed to thrive. And although there's an element of surprise that we have done what we've said we'd do, it has been many years in the making.
What were the biggest hurdles to the creation of Chi-X?
There were three main challenges. The first was to ensure that our market model was able to answer the various demands of customers, i.e. to handle the characteristics of stock trading specific to Europe. The second challenge was perhaps the most significant: to offer customers a fully anonymous and centralised clearing and settlement solution. We worked with customers and partnered on a non-exclusive basis with Fortis to develop the EMCF (European Multilateral Clearing Facility) initiative, which has proved very powerful in allowing a reduction in price, increase in competition and a credible alternative to the mantra of the incumbent providers that the only solution is consolidation. Monopolies appear to believe that only by building even stronger monopolies will they one day be in a position to lower prices. I don't think that the market has ever believed that. The third challenge was that we had to take a view 18-24 months ago on what actually MiFID meant. And there was no one 24 months ago that was willing to provide a clear, executable interpretation. So we had to sit down and decide for ourselves. That was a big risk to take. Fortunately thus far we seem to have called it more or less right.

How is Chi-X attracting liquidity from traditional exchanges?
I'd like to correct an assumption: we're not actually taking market share from the established exchanges. I believe to a large extent we're bringing new liquidity to the market, new business that couldn't previously be done in Europe, because the price charged by the exchanges was wrong for particular trades or the technology platforms were too slow or suffered from capacity constraints. We have a very cheap, very high capacity, very fast platform. This means we can attract new liquidity - it's not a zero sum game.
How is Chi-X appealing to users of algorithmic / automated
The only way in which [execution] algorithms can work is by
getting better prices for their customers. Chi-X consistently has
better prices than can be found on the other exchanges. For a
TWAP algorithm that's going into the market multiple times per
day, the value of being able to access the lowest prices
consistently is considerable.
We don't incentivise algorithmic trading through price as you can only access our liquidity electronically. Our pricing structure is completely flat. If you take liquidity from the market we will charge you 0.3 of a basis point, if you add liquidity to the market we will rebate you 0.2 of a basis point. The reason why our pricing is so low is that we have a low technology and employee cost base - it doesn't take as many people to run Chi-X as it might an large stock exchange.
What are you plans for the next 12-18 months?
We will expand in two ways. First, we will bring more
participants into the market and we have a busy pipeline of firms
who wish to participate - either by getting connected themselves
or connecting via third-party vendors offering proximity
hosting/co-location hosting solutions to help clients achieve
near-zero latencies. Second we will be continuing with our
programme of introducing more European markets to these
We have been pleased with the modest but daily increasing volumes. I can't comment on market share expectations, however it is worth looking to the US where some 20-25% of equity trading is conducted on ECNs.
"That which technology enables to be split apart can also be knitted back together again."
How will you bring more participants to the market?
There are two main reasons why more participants will come.
First, as volumes increase, more brokers will want to play those
volumes, because they see the price improvement and understand
that we're offering their customers the opportunity to get better
pricing. If you can save two or three basis points for your
customers by trading on Chi-X, they will demand that you go to
Chi-X. Why would you go to another platform that would give you a
less good price?
Second, Europe is beginning to show clear signs of voting in favour of competition and against consolidation. More people believe that having a competitive marketplace is desirable. If competition means fragmentation, that's not a bad thing. That which technology enables to be split apart can also be knitted back together again with technology such as smart-order routing. You can use SOR to pull in the prices and then decide which trading venue to use.
will liquidity fragmentation mean for traditional exchanges?
The only thing that will allow brokers to make decisions around best execution obligations is the ability to establish and capture best price for a particular equity on a particular day. So in a sense the sine qua non is that exchanges have to be technologically capable of including their prices in the common pricing feed. Realistically the only way they can do this is electronically. Platforms that have minimum electronic input are going to be disadvantaged.
How does Chi-X achieve such high trading speeds?
Don't ask why we're so fast; ask the incumbent exchanges why
they're so slow. The answer lies both in the nature of the
exchanges themselves and the process through which they
originally computerised their trading operations. The challenge
facing the exchanges is to adapt their existing capacities,
technology architecture and infrastructure and offer open access
The breakthrough that the ATSs (alternative trading systems) and ECNs made in the US was to realise that the matching algorithm is relatively trivial compared to the real challenge of optimising the input/output queue, i.e. how do you get people in very fast and out very fast. And that's what we've done too. If you get your messages in and out very fast, the job's done; it doesn't matter how neat or elegant your matching algorithm is. It's not a question of why we're so fast, because we're only as fast as the technology can go. But the incumbent exchanges haven't addressed this for so long because they're monopolies and have had no incentive to adapt. The good news about MiFID is that it opens the doors for competition and for the first time in Europe investment firms are offered choice.
What kind of trading experience can users expect on Chi-X?
Our matching rules are purely price time priority. Although we do
support dark liquidity by allowing people to place non-displayed
orders, a displayed order will always take precedence over a
non-displayed order. Our capacity at the moment is around 30,000
transactions per second. Adding capacity for us is simply adding
more servers, because Chi-X has been designed to be scalable as
an article of faith from the outset. In terms of trading speed,
it depends how you connect, but generally we are giving a round
trip of 2 milliseconds for remote connections; if you co-locate
that is 690 microseconds.
We can provide all levels of consolidated data for free via the Chi-X Multifeed in a very standard, normalised package. Chi-X Multifeed includes all bids and offers, regardless of whether or not they were taken up; effectively, we give you the tape, so you can see all the details, for example, which side was the aggressor in any deal.
What technology developments are planned in next 12 months?
We will continue to invest in the next generation of the platform and are actively planning for new functionality. Smart-order routing is something we'll be offering shortly. A smaller broker who maybe doesn't have the technological sophistication of the global brokers can come to us and we'll check our price against other exchanges; if it doesn't match on Chi-X, we'll send it to another exchange. We'll route to them and hope they'll route back to us. If we have a better price, they should send deals to us, shouldn't they? We hope to be offering that this year. There are a lot of smaller brokers and services like this will level the playing field - it democratises the market.
