Flash Mobs of Trading Robots Coalescing To Rule Markets

An anonymous reader writes "Financial markets experienced a series of computer glitches recently that brought operations to a halt. According to a researcher at the University of Miami, mobs of ultrafast robots, which trade and operate at speeds beyond human capability, may be responsible for these "flash freezes". From the article: '"Even though each trading algorithm/robot is out to gain a profit at the expense of any other, and hence act as a predator, any algorithm which is trading has a market impact and hence can become noticeable to other algorithms," said Neil Johnson, a professor of physics at the College of Arts and Sciences at the University of Miami (UM) and lead author of the new study. "So although they are all predators, some can then become the prey of other algorithms depending on the conditions. Just like animal predators can also fall prey to each other." When there's a normal combination of prey and predators, he says, everything is in balance. But once predators are introduced that are too fast, they create extreme events.'"

It takes a minute for a buyer to be matched up with a seller organically, and in the meantime the HFT algos buy up all of the $10 sell positions and immediately put new sell orders out for $10.50.

      And can you explain how higher spreads are better for you and not for the middle man? I mean the spread is how they make their money. You have to pay more to buy the stock and you get less when you make the stock. I can’t think of good thing about that.

      I am going to have to contest you logic on volatility. If that were true then dual listed stocks (e.g. stocks listed on both the Paris and London exchange) would have about the same volatility. One of the ways that HFT make money is to exploit the price differences on different markets. If markets were frictionless then the same stock on different markets should have the same price and volatility. The tobin tax introduces friction. After the tobin tax the volatility of stocks in the Paris exchange was higher than that of London.

      And as a aside, there has been an argument about HFT, volatility, liquidity and spreads. The general concusses is that HFT increase liquidity and decrease spreads during normal operations and that this is a good thing. (flash crash aside). Some have argued that they increase volatility, such as flash crashes, which is a bad thing. However the proof of this is currently weak. The argument goes on.

    One criticism have about the content of the article is that the while the authors argue that the UEE's (the fast price spikes) aren't correlated with news events and can't be explained by random behavior, they don't really address another obvious source of UEEs: hedgers or speculators in the market who are liquidating a position as part of their **long term** needs or trading behavior. Ie- how do they know these aren't market orders (eg- Sell 100 APPL) placed by some guy day trading his brokerage account? If the order book is populated at a few lots per price level, a larger market order will momentarily cut through those levels and then recover. I think they try to sweep that issue under the rug by claiming that the trading volume during these spikes is not appreciably different from trading volume during quiescent times. OK, but it doesn't address who placed the order and why, and what are those volumes anyway?

    A second criticism I have is that they explicitly imply that there may be "degree of causality between propagating cascades of UEEs and subsequent global instability". I see correlation here, but no causality. Indeed, if there is global instability, a lot of people in the market will be unwinding positions, and you will see a lot of UEEs as they do so. In other words, there is a strong common sense case to be made for causality **in the other direction** than what they are claiming. I would need to see better evidence than just an overlaid plot (figure 1C).

    Finally, and this is more of an observation, does anyone pay attention to how fast the price recovers after a UEE, for whatever reason it originally happens? The recovery happens so quickly because of the dreaded high frequency algorithms. What did UEEs look like ten years ago - when someone came along and sold 100 shares of X, did the market take minutes to recover? That it comes back within a second seems like progress to me.

    It's a mistake in the making



    From the painful cries of mothers To the terrifying scream We recorded it and put it into our machine



    Then they told us, all they wanted Was a sound that could kill someone From a distance, so we go ahead And the meters are over in the red

    It's a mistake in the making



    It could feel like falling in love It could feel so bad

    But it could feel so good It could sing you to sleep



    I'll bet my mum's gonna give me A little toy instrument

    But that dream is your enemy



    We won't be there to be blamed We won't be there to snitch I just pray that someone there Can hit the switch



    But they told us, all they wanted Was a sound that could kill someone From a distance, so we go ahead And the meters are over in the red

    It's a mistake we've made



    And the public are warned to stay off ...
