While I don't think high volume trading platforms are bad per-se, I understand what the author is highlighting. Anybody that knows computer systems understands that computers can do a huge volume of really stupid things based on what they were programmed or told to do by an operator, before the breaks get applied - and it takes a person to determine if the actions were ultimately negative.
Trading <> Investing. Computerized trading has destroyed investing for the "average Joe", or low volume, long term investors who look at business and industry fundamentals instead of algorithmic trading pattern theories. Today, much of the trading volume is driven by momentum.
I now invest in bullets and things that have tangible value for life and healthly living. I'll leave the "trading" up to my Electrical Engineer brother who studies the theories and works tirelessly gaming the platforms just to break even.
The author talks about “the little guy,” “marks,” and “the regular joe” trading on the CME.
People like that should not be trading on the CME.
If they are, limit orders and stops could keep them out of trouble 95% of the time.
