Quote from steenbab:
I appreciate this thread regarding my articles and hope to make a few clarifications. As the quote from the initial posting indicated, I am not questioning that traders can trade successfully in a discretionary manner. In my work as a director of trading at a large Chicago proprietary firm I have directly observed quite a few multimillion dollar earning traders. None of them traded with technical analysis strategies, and none of them relied on research or mechanical systems. They truly were and are discretionary traders.
The problem, rather, is that such traders do not, as a rule, *maintain* their success. When market trends change, when patterns of volatility shift, their sensitive reading of the market no longer serves them well. I cannot tell you how many active traders I've observed who were successful during the momentum days of the late 90s and early 2000s, only to come to ruin in the past two years. My observation, as one who has directly observed them and worked with them, is that their problems are not primarily psychological. Instead, I believe it to be a problem of learning: patterns that were learned and internalized over many, many hours of market experience no longer show up in the market. By the time they have an opportunity to learn and internalize new patterns, they have experienced much loss and frustration.
Note that I am *not* advocating trading by mechanical systems. Those are based upon exploiting patterns that also will change with shifting market regimes. My experience tells me that discretionary trading can succeed when aided by research that allows a trader to know when market cycles are changing and when they can be counted upon for continuation. An analogy would be that of the fighter pilot, who relies on reflexes and the implicit learning that comes from long hours in simulations and real-time exercises, but who also must be guided by satellite intellligence, radar findings, instrument readings, and other "research".
The goal is not just to be successful, but to sustain success. I believe that can be most easily accomplished if hard, objective findings can tell the trader when recent market conditions can be counted upon and when they are changing. Such trading is neither wholly discretionary, nor mechanical. It is informed.
Thanks for the opportunity on the soapbox!
