HFT/Algo's (Knight Capital): Side story post today:

These are headlines I see this AM... 

Knight Capital see's pre tax loss of $440 million.  Capital base has been severely impacted.  Knight Capital falls 40% in premarket trading.  Software has been removed from company systems.

I strongly believe the greatest trading system in the world is a discretionary one with strict rules for "Money Management", "Trade Management", and "Risk Management", that enable a trader to be systematic or mechanical in his approach. 

It still amazes me that trading firms want quants and computer programs to hire as futures traders.  It is a zero sum game.  The basic math say's there has to be an enormous number of them that have as bad or as destructive a performance as a rookie impulse trader.  With the chance that you get what Knight Capital just did when things go really wrong.
