London Stock Exchange Finishes Switch To Linux 106

DMandPenfold writes "The London Stock Exchange has successfully set into live trading a new matching engine based on Novell SUSE Linux technology, following successful last-step setup procedures on Saturday. The move has been billed as one of the LSE's most significant technological developments since the increasing prevalence of electronic trading led to the closure of the traditional exchange floor in 1986. LSE chief executive Xavier Rolet has insisted that the exchange, once a monopoly, will deliver record speed and stable trading in order to fight back against the fast erosion of its dominant marketshare by specialist electronic rivals."

      Even if Microsoft bought some rights from Novell via the Attachmate deal, the current stack is *not* Microsoft tech. The Accenture/MS solution (TradElec) was binned as it was problematic, it crashed for a whole day [practical-tech.com] and it never reached its performance targets (using Server 2003 and SQL 2000 [computerworld.com]). The CEO who had brought it in was apparently fired [computerworld.com].

      You couldn't be more wrong. The absolutely opposite is true. Algorithmic trading is exactly what the exchanges want and here's why:

      Increased trading means increased fees. Exchanges charge a fee for each and every order. MTFs such as Chi-X and Turquoise grabbed market share by having a clever pricing structure based on whether your order is sitting on the order book and filled (passive) or your order is immediately filled against something already

          I didn't say cobble together. What I meant is Linux runs on big iron, it runs on PC architectures, it runs on racks. Multiple architectures, multiple roles, same OS. It makes it easier to put the system together when everything is running the same OS. I imagine that a system like a stock exchange would have embedded systems with honking amounts of memory for low latency streaming / quotes and large mainframe backends for recording trades. All tied together with the fastest network / backbone you could lay your hands on.

          My understanding is the previous system was .NET over windows which raises large question marks over performance (e.g. unexpected garbage collections) and the sort of hardware that it could be run on.

          Actually, these types of things are usually in house. If there ever was a case for non-off-the-shelf software, a SE booking & matching engine is it. Most of the developers will be inhouse. The reason to use Linux is most likely that you can strip out all non-essentials. A path that an order takes from external interface to execution can be seriously streamlined with little intereferance from the OS.

          It sucks money out of the stock market.

          Fans of it will say it provides 'increased liquidity'.

          Me, I say, it sucks monkey out of the stock market. If it didn't the HFT people wouldn't bother doing it. The money comes from somewhere, and that somewhere is other investors. If it *doesn't* come from somewhere then creating it means there's more money and it comes from everyone via inflation.

          That's my take. May be wrong, may be dense, but that's my take. Me, I'd scale back the whole thing massively because I still haven't had anyone explain adequately to me how, after they've gone public, the company's stock market valuation matters (to the company) for anything at all, except for perhaps their ability to rack up debt.

            "increased liquidity" has a cost.

            If you want to buy now, or sell now, instead of spending a few days shopping for a willing partner on the other side of the trade you won't get as good of a price. But you also have the reduced risk of not spending a few days trying to unload your stock.

            The one thing that you will notice is that with the high frequency traders the spread is now very small, but the volitility is much higher, so in some ways this is a reaction to discount brokerages and the decimalization of stock prices, as the fees are not in the spread but in the volatility. I don't know which is more profitable to the house, but the reduced spread and the greatly reduced commissions had to be made up for someway. Banks are more profitable now, but there are many fewer banks, so direct comparisons with thirty years ago are not possible without correcting for industry consolidation.

            An example of the cost of liquidity is that, while exchanges are liquid, someone selling five to ten percent of a company in the open market in a few minutes can easily erase more than half of the companies market capitalization. But the stock is sold and the books are closed.

            One difference between specialists and high frequency traders is that specialists have to be the buyer and seller of last resort, while HFT's have no obligation to make a losing trade.

            I have not looked at the math behind technical trading recently, but in the nineties there were several papers published that suggested that technical trends could only see about 15 minutes into the future, and the predictive value more than five minutes into the future was murky, but not useless.

            As far as your question of how a companies market capitalization matters to the company, it depends on the company. Some companies carry a large number of authorized shares on the balance sheet, but do have not issued them. The company can give bonuses as stock options which if the options are deep in the money, the investors are essentially paying a substantial percentage of employee compensation, instead of the company paying it. A high market capitalization does not guarantee that people will loan you money, but it does tend to lower your interest rate, and allow you to issue really long term debt. (Disney and Coke issued 100 year bonds, Canadian Pacific issued 1000 year bonds.) One other thing that companies can do with an over inflated market cap is buy things with the stock, see aol buying time warner as a famous example of that. I am sure that there are uses that I am forgetting at the moment. But I hope that is somewhat illuminating.

            If the company's stock is highly valued they can finance growth by selling shares. Otherwise they would have to "rack up debt" in order to grow.

            The whole point of the stock market is it's not a zero-sum game - the companies you invest in are creating wealth (by building a better mousetrap, from materials and labour that are worth less than the finished product), which goes to their owners, i.e. the stockholders.

            Now, you're right in that the money that HFT guys make comes in the immediate from other investors. So flip it around: if all they're doing is creaming off profit, why would anyone ever buy from them or sell to them. Answer: they give you th
