Michael Lewis – Flash Boys Audiobook

If you have been watching economic information this week, you will have heard that the British extra pound collapsed in a “flash collision.” Most news stories leave it at that. (I believe that’s due to the fact that they don’t know what a flash accident actually is.) Simply put (and in Flash Boys Michael Lewis describes this reoccuring phenomenon rather simply) a flash collision is how high frequency investors use computer systems, multiple exchanges and time to abuse the regulations. Now that I have actually summarized that, let me back up a second and deconstruct the sentence. Initially, what are the regulations? In 2007, after brokers were discovered to have been abusing consumers’ depend on as soon as too often, the government brought out what’s called Reg NMS. This regulation (and also below I am simply going to price quote Michael Lewis straight due to the fact that I don’t believe I can state it any kind of far better than he did). Flash Boys Audiobook Free. Reg NMS mandated that brokers purchase shares at the most effective rate. “To define best price, Reg NMS depend on the principle of the National Finest Quote and also Deal. If a capitalist desired to purchase 10,000 shares of Microsoft, and 100 shares were provided on the BATS exchange at $30 a share, while the complete 10,000 provided on the other twelve exchanges were offered at $30.01, his broker was required to purchase the 100 shares at Bats prior to proceeding to various other exchanges.”

This indicated that anyone with a computer system can see where an acquisition is mosting likely to be made and for how much. So if you have a faster link (as well as several exchanges where you can sell a few shares of a stock, you can currently see how you can earn money.) Certain, you will not make a great deal of money from any one trade. Perhaps less than half a cent right here as well as half a cent there. Yet that adds up. I recognize this from first-hand experience. Recently at work, I was attempting to calculate what would the expense be of a service was left out from a bundle of services. And also my computation maintained being virtually a billion off. I did it as well as re-did and re-did it in all directions I might consider. I also pulled down my statistics book to see if my mathematics was off. Nothing. I got up and went for a cup of coffee just to pause from this ludicrous problem and when I sat down once again, I saw it. It was a rounding mistake. To be precise it was a rounding mistake in the one/thousandth decimal location. However I was handling billions of dollars which rounding mistake made fairly a difference. So indeed, parts of cents accumulate. But wait, there’s even more.

The means the most effective cost is calculated is when an exchange computes all the bids and offers on a specific stock. This calculation is done by a federal government computer system as well as if you know something about government, you will recognize that it takes years to update computers. That suggests that if you have your very own, quicker computer system you can “front-run” the authorities finest rate and sell and buy 100s of shares at the “real” finest rate. Sure it will certainly be a “rounding error” however as I said before, those rounding mistakes issue. So a regulation that was meant to create equity and openness in the market in fact institutionalised inequality in between the traders who had access to the super-fast computers and also those who did not. Just the previous would earn money from these rounding errors.

However wait, there is yet a lot more. To make full use Reg NMS you additionally require many different exchanges or dark swimming pools as well as dark wires. And guess what, both exist. Dark wires are cords that are maximized for rate of transaction. Certain it’s a millisecond distinction or perhaps much less but in that time you can get a lot of rounding errors. Dark swimming pools are, fundamentally, exclusive exchanges. They exist to make it much easier for institutional financiers (like the people to whom you delegate your pension plan as well as mortgage, for instance) to trade in huge blocks. So, for example if you have one million shares of Microsoft you wish to market (or acquire) however don’t desire your identity understood, you would rather sell/buy those shares far from the obvious eye of the public transaction. Here’s the problem, if your are a high frequency trader, you (necessarily) have a super-fast computer and access to dark cords. That means you can “ping” the many, numerous dark swimming pools that have been set up. By some estimates, 40% of all trading is currently done inside dark pools.

And that in turn implies you can understand, well prior to the government-issued sluggish computers have actually completed determining the best cost what the genuine selling price is. That’s one hell of a rounding mistake in your pocket.
