Cybernetic Trading Systems

In DEEP Investing, INTELLIGENT Investor on January 4, 2011 at 2:59 PM

“Cybernetics was defined by Wiener as ‘the science of control and communication, in the animal and the machine’—in a word, as the art of steermanship.”

–W. Ross Ashby


Cybernetics embodies a multi-discipline theoretical framework which focuses on goal-directed systems.  These systems use information, models, and control actions to steer towards and maintain a predefined objective while attempting to counteract anything which detracts from this objective.

Perhaps the most fundamental innovation of cybernetics is its explanation of purposiveness, or goal-directed behavior.

ASEAN Trading Link countries: Singapore, Thailand, Malaysia, Indonesia, Vietnam and the Philippines

The long-awaited ASEAN Trading Link may do more to stimulate both investment in the Philippines and Filipino investing than any other current development.

According to the PSE Info Matrix a Memorandum of Understanding was signed earlier in the year between the exchanges of the Philippines, Malaysia, Singapore, Indonesia and Thailand. Within twelve months, investors based in any of these countries will be able to buy stocks on the index of any participating ASEAN exchange, just as easily as purchasing at their home exchange.

In INTELLIGENT Investor on May 5, 2010 at 11:02 AM


John Bogle help us.

Vanguard Group Inc., the largest U.S. provider of stock and bond funds, is deciding whether to keep Axa Rosenberg Group as manager for about $1.5 billion of its assets, after that firm said a “coding error” disrupted its quantitative investment process.

Interesting insights from a pre-high frequency prop trading perspective.

This is a totally different angle from your typical retail trading experience.

Mechanical Trading Systems by Richard Weissman

In BOOK Review, DEEP Investing on February 21, 2010 at 11:18 PM



“The greatest benefit of mechanical trading systems is their ability to reprogram traders away from destructive types of behavior in favor of successful trading habits.”

–Richard Weissman

Perhaps W. Edwards Deming said it best: “If you can’t describe what you are doing as a process, you don’t know what you’re doing.”

I can count on one hand the number of traders I’ve met on the Philippine Stock Exchange trading floor who can describe every facet of their trading as a process.  True, some veterans can kick butt trading ‘by their gut’ but they are few.  I suspect the majority let their emotional state or whims of the moment play a inappropriately large role in putting on trades.

If you’re serious about your trading, you’ll systematize what you’re doing.
