The volatility created by their trading is essentially invisible to a retail investor who observes the markets day-to-day rather than minute-to-minute.&lt;p&gt;It seems to me that people are fixated on volume, which is essentially an irrelevant figure - holding a big position for a couple of milliseconds has no meaningful impact on anyone but other HFTs. If we smooth our data to a resolution of minutes rather than milliseconds, market behaviour looks no different today than a decade ago. Even a supposed disaster like the &quot;flash crash&quot; of 2010 corrected itself within five minutes.&lt;p&gt;I&apos;d be curious to see if the same debates were happening when computerised trading was first introduced. The magnitude of change was far greater, but there&apos;s broad consensus that computerisation led to fairer and more efficient markets. I just don&apos;t understand how faster trades can be bad in and of themselves. If your objection is to speculation in principle, then by all means argue for a Tobin tax; I just don&apos;t see why it matters very much whether that speculation occurs over the course of days, hours, minutes or milliseconds.</text><parent_chain><item><author>lifeisstillgood</author><text>At what point will HFT drive out the proper functioning of a Market?&lt;p&gt;Have there been any studies on this?

High frequency trading slices the gap between offer and purchase into an enormous number of tiny slices, and HFT companies compete to see who can collect the most number of slices. But that does not affect the underlying factors that lead to most offers and purchases of stock.&lt;p&gt;For example you could offer OJ futures at improperly high prices a billion times per second, but that does not mean anyone will buy them. I&apos;m not aware of any evidence that Amazon&apos;s weird million-dollar books have affected the price of popular new books.&lt;p&gt;In addition, I wonder by what criteria one would evaluate how &quot;properly&quot; the markets are functioning. Who decides what is proper? For example, based on the business fundamentals it seems ludicrous to me that Apple would have a lower P/E ratio than GM--but it currently does.</text><parent_chain><item><author>lifeisstillgood</author><text>At what point will HFT drive out the proper functioning of a Market?&lt;p&gt;Have there been any studies on this?
