TradeTech Europe 2011 is the largest and most senior meeting place for the electronic trading community. It gathers over 2,000 buy side traders, brokers, trading venues, regulators, industry experts, economists and fund managers. It is created by the industry advisory board and is highly valued by all participants. TradeTech is designed to give you true value and help you grow in your job, ensuring top results and great performance for every member of your team. The work on the conference agenda is full steam ahead. We are interviewing hundreds of your colleagues and peers from buy side institutions across the globe to find out exactly what they would like to take away from the conference agenda and the exhibition floor.

1. Interview with Guillaume Lemarchand, Global Head of
Execution, BNP Paribas
1. What do you expect MIFID 2 to change for your business? How will your
business change as a result of MIFID 2?
I anticipate that MIFID2 is going to be a clarification exercise more than anything else,
and do not expect to be the catalyst of a radical change in our business model, nor in the
business models of our competitors. The fate of Brokers Crossing Networks will be of
particular interest though, and will potentially yield changes in strategy. I also hope that
the revised regulation will induce further playing field leveling, as some national
inconsistencies do persist and have worked to the disadvantage of continental brokers
like BNP Paribas – issues like the ‘Riskless Principal’ flag usage for instance.
I do expect MTFs and Exchanges to be more affected than the Sell Side as the difference
in regulatory treatment between those two categories of venues is quite significant; but I
do not anticipate massive changes on this front either, as the regulators will work under
constraint. They need to be careful not to impose too costly compliance requirements, in
order not to impede the painful emergence of sustainable (ie profitable) alternative
venues.
2. With the liquidity becoming more concentrated, do you think buy side really
needs access to all the alternative liquidity?
I am not sure to fully agree with the “concentration” statement. You’re probably right in
the lit space, as the landscape seem to have pretty much stabilized. The fact that a
number of MTF initiatives have failed does not necessarily mean that liquidity will be
easier to grasp. And let’s face it, despite all the marketing noise, failed MTF initiatives
had never been significant pools of liquidity anyway. Any a new type of alternative
venues is emerging.
The main difficulty is that we now have to venture in the dark space. Granted, as of today,
one could question the real interest for the Buy Side to access the liquidity offered in Dark
books of Exchanges and MTFs; they so far remain an epiphenomenon, and their liquidity
is mostly made of small-sized market makers orders. But statistics show they are growing
at a fast pace, and they should ultimately become of some significance; moreover, since
the main Brokers are all connected to those pools thru existing lit pipes and SORs, they
will natively be made available to the Buy Side. So even if the Buy Side does not really
need access to that Dark Liquidity, they’ll have it!
What has become more important to the Buy Side is systematic access to the Brokers
Crossing Networks, where an increasing share of trading is made, in the dark. Those
pools are significantly deeper and more persistent than the Exchanges and MTFs dark
books, as they’re mostly made of “real” institutional orders. Some brokers had even
started interconnecting their BCNs, and accessing that liquidity had become easier. As
MIFID2 is looking at framing the BCNs and could stipulate that those can no longer be

2. interconnected (to prevent the formation of a “preferential group of insiders” and ensure a
sufficient level of transparency), the Buy side will probably have to split their large orders
into several brokers operating BCNs.
3. Do you think the trading community will start going back to simple algos and less
complex liquidity, or will the race for sophistication continue?
In the 3 regions where we operate, we have witnessed very similar evolution patterns in
the algorithmic trading acceptance
Invariably, you’re first faced with incredulity: “algos will not work in this market or segment
as it is so specific that only an experienced dealer can handle it”. Quickly, this changes
into partial acceptance: “ok that works for the large caps, but small caps or complex
orders I’ll trade them myself”. Then you start addressing particular stock segments,
trading patterns or client requests. Eventually you end up creating tons of specific algos,
making sure you assign a military name to each new weapon in your arsenal. So many
that you’ve now blurred the message: clients and brokers no longer know what to use,
and stick to only a handful of algos.
And when you look at what Clients use most, you unsurprisingly find out that the Buy side
traders mostly rely on 3 algorithms only for over 95% of their flow: Vwap, Volume
participation and Implementation Shortfall. When you then take a deeper look into the
algo boxes, you also realize that most recent “innovations” by the Sell Side are mere
parameterized combinations of those 3 basic algorithms.
I am not saying that we only need 3 algos and that the rest of the weaponry needs to be
binned. Our most sophisticated Clients still ask for custom algos and dedicated Desk
Service. But I guess that the main challenge for the Sell Side is to make sure their suite
of algos remain readable and intuitive to the Buy Side. At BNP Paribas, we have
therefore opted for a slightly shorter product suite; Our large research teams spend more
time tracking the behavior of our core algos than repackaging old algos into new ones,
making sure our core algos remain best in class in terms or absolute performance and
standard deviation. We also keep investing in pre-trade, intraday and post-trade analytics
as those are fantastic tutorials, which help us as well as our Clients decide which
algorithmic combination works best.
Meanwhile, the innovation race continues, but on other fronts. This maybe invisible to the
Buy Side but SOR algorithms have been heavily invested in as Dark venues come with
all sort of different order placing logics; anti-gaming logics have been incorporated;
algorithms have also become part of the standard Listed Derivatives trading kit.
Eventually, I believe in the development of contingent portfolio trading algorithms, even if
those would probably be best developed on vendors trading platforms, not by the Sell
Side.
