What Makes High Frequency Trading Work

You’ve heard about computerized securities trading and what’s called high frequency trading. There was a lot of talk about this related to the “flash crash” last spring. But like it or not, we are in the era of automated stock trades. Some are initiated by human traders. Others are triggered by algorithms pre-programed to wait for certain conditions and then place the buy or sell orders automatically. Now, CBS News has gotten an inside looks at the machinery that makes this all possible. Watch “Robot Traders of the NYSE” and see if your jaw doesn’t drop.



Did you catch the part about how they had to equalize timing for all traders to keep the system fair? Once they started up this 3 football fields size data center, it turned out that where your servers were located physically in the infrastructure determined how fast you could get your trades to market. Yes, just the length of the cabling and whatever routing equipment was involved gave near-end locations an edge over far-end locations. How much can this really be? It was only microseconds, but in high frequency trading microseconds count.

The NYSE leveled the playing field by equalizing the access time to 65 microseconds for all players. Now, no one has an advantage... or do they?

Not all trading is executed on the New York Stock Exchange or on computers collocated within the NYSE facility. You could be trading other exchanges in New York, New Jersey or Chicago. You may need to access an overseas market from the US or vice-versa. What many broker dealers, investment management firms and hedge funds have done is collocate to a commercial facility, such as the ones that Telx operates close to major financial districts. Telx focuses on ultra-low latency connections to speed transactions to market. Through a partnership with Tata Communications, Telx offers colocation facilities in Canada, South Africa, Europe, UK and Asia. Telx and other carriers also now offer line services designed specifically for the lowest latency possible.

Do you have a requirement for unusually low latency facilities or connections? Find out what’s available in International International Low Latency Data Networks now.

Business Booming For Telx Interconnection and Colocation

While many companies remain hunkered down and wringing their hands while they wait for the economy to improve, colo provider Telx is on a building boom at their premier data center in Chicago. What kind of sense does that make in recessionary America?

It makes lots of sense if you’re clued-in to what is transforming business and finance. It’s been a long time since accountants wore green eye shades and engineers worked slide rules. Most companies have adopted computer-based workstations connected to servers in the back room. This client-server architecture had a lot to do with increasing the speed of doing business and improving employee productivity in the last few decades. But now some of the savviest companies are adopting new methods and systems to give themselves an edge over their competitors.

Remember when the original justification for computerizing processes was elimination of paper? The “paperless office” became a joke as cheap laser printers and copiers spit out reams of paper faster than they could be hauled to the recycling bin. But when you consider how the speed and volume of transactions has increased, every desk should be piled to the ceiling and the aisles crammed full of paper documents. All the paper you don’t see is in the form of bits and bytes on hard drives spinning away inside your computer and in network storage within the data center. It’s turned out that less paper is the minor benefit of computerization. The big benefit is speed.

We simply do more faster. Companies don’t mail us product brochures anymore. We pull them up online. The time from identifying a need to researching solutions to placing an order has shrunk dramatically. It can all be done from the comfort of the desktop, sometimes in a matter of minutes. Need to coordinate team activities? Let them collaborate online so that those in Seattle can mark up documents for those in New York in real time.

Nowhere has the demand for speed become more dramatic than in the financial industry. You’ve heard of high frequency trading? These are complex algorithms running on high speed servers to electronically issue buy and sell orders to the markets. We’re at the point where milliseconds and even microseconds make a difference in trade profits. The Einsteinian limit of how fast light can move through glass and wire introduces a time delay between locations that simply can’t be reduced. So, how do you beat the competition? You get closer to the markets... physically closer. That’s what Telx provides. Its proximity to the exchanges and the buy-side and sell-side firms at Telx’s strategically collocated facilities. If the upper limit to your potential speed of transaction is a length of patch cord, you are in an advantageous position compared to the competitor hundreds or thousands of miles away.

Low latency colocation facilities near the action are essential for the most advanced players in high frequency finance. But there are other reasons for collocating with suppliers, customers and service providers. The cost of bandwidth is a good reason. With many competing carriers within arm’s reach, or at least down the hall, you’ve got access to the best rates per Mbps or Gbps and none of the expensive build-out costs of stringing wires or fiber cable for miles. If bandwidth is becoming one of your biggest expenses, moving to the colo facility can be a major cost saver. This can easily be the case if your product is video or high volume e-commerce or a popular application with millions of users.

Even smaller companies that aren’t located in a downtown sweet spot for low bandwidth prices may find that colocation gives them the advantage of keeping their physical location where it is but moving their bandwidth-hungry applications to where costs are lower. Cloud computing is another way to leverage the economy of scale in putting the software and servers where the bandwidth is cheapest and accessing the service from wherever you choose to be.

Does your company have demands for low latency or high bandwidth that would benefit from Telx or similar facilities? Are you just looking for ways to reduce your bandwidth costs? If so, you should take a look at the cost advantages of colocation and cloud computing services.
