Interesting post, and also thanks for the links, Mich.

In response... the financial firms in the US generally (not all) 
claim that the expertise of their money managers will make their 
clients money... and when describing the trading strategies of these 
money managers, the strategies steer clear of TA, and point toward 
fundamental analysis instead -- sector analysis, projected EPS, cash 
flow, etc. The consensus for the most part among these firms is that 
TA is witchcraft and does not work.

Some of the trading systems located at the following links are 
automated and make money consistently without human intervention... 
see --

http://www.collective2.com 
http://www.traderscue.com 
http://www.timertrac.com/Public/Investors.asp
http://www.systemrank.com

One thing people often forget is that a trading system may be 
created by combining a collection of automated trading systems. The 
system that trades at any given moment may be selected according to 
various market environment factors. A combnation of systems may also 
be traded in the same way.

I have stopped looking for "scientific evidence" that TA works, 
because I have personally experienced that it works, consistently, 
for myself. Remember, too, that science has failed to identify solid 
matter -- each time a subatomic partical is broken into, it reveals 
smaller particals that are made up of "probability fields." Yet, we 
still live and fucntion within an entire paradigm that makes the 
grand assumption that we and everything around us "really exists."

I'd write more but I have to eat dinner now.

Thanks,

~Bman
