Algorithmic Trading article

Thanks for the very interesting article, Steve

From the info I gather, UBS, Goldman and CS are moving increasing portion of their trades away from the exchanges and into their internal network. The percentage of trades their did over their internal network by now has been 12% and predicted to be 18% by 2010.

More internal trading, more algo trading, I imagine your group would see more action in this direction. Would you be able to share with us your experience with your group with regard to this very exciting trend ?
Thanks
 
Andy, I am currently attached to a research group rather than a trading desk.

When I was at Lava Trading, there was definitely a wish in equities trading to cross more trades internally than on an exchange.

Not sure how the introduction of Reg NMS affects this process. I would have thought any internal cross should have its price exposed on the exchange to comply with Reg NMS.

Impications of RegNMS on internalization

Folks:
One implication of RegNMS on firms internalizing orders is that if they
cross an order internally at a price better than the displayed BBO of the
market, then they must make good on all of the current orders at the top
of the book at each market center.

As a consequence, keeping track of the state of the market at the time
a trade was executed is now a very important compliance issue. This is
one reason why you are seeing an increase in interest in real-time tick
databases (e.g., StreamBase, Vhayu, Kx, etc.)

Cheers,

Prof. H.

Reg NMS Implications for liquidity, both displayed and hidden:
--------------------------------------------------------------------------
Most flow will go through smart order routers that ping all intermediate price points across many venues.
Bids will therefore get hit regardless of if they're displayed or hidden.
Therefore, hidden orders will massively proliferate in both NYSE and Nasdaq names being placed on cheapest and most liquid venues.
Visible spreads will widen, 'real' spreads will be tighter than ever.
Less order information will fly around the Street. No one will know who's been buying, who's been selling, or how much anyone leaves.
As signaling is reduced, slippage will decrease on average.
Volume will increase tremendously.
