Real Traders, think about this...

We do not expect one trader's methods to automatically work for
another trader.

Why?

Because of differing personalities, what works for one does not
work for another.

So, for the same reason, we can expect that my methodology would
not work as a mechanical system. 

Why?

Because the software does not have my personality either. The software
will tend to blindly trade my rules. And it will tend to ignore subtle
variations in my decision-making process, because the software will be
much less flexible.

Here is an example..

Much of what I trade is pattern-driven. We would expect software to be
able to identify a pattern as well as a human can. But it can't. Think
of an elephant. Can software scan through a thousand images and present
a list of every image that contains an elephant? No! there are too many
variations, elephants have different colors, sizes, and they stand/sit
or lie down in an infinite different ways. Some elephants are partially
obscured by trees. Some have distorted mirror-images reflected off water.
No software can identify every elephant image. Software will make many
errors in such an exercise. But a human can do very well at this (not 100%).

It's very similar with chart patterns, they can be the same pattern, but
there are an infinite number of variations.

For this reason, current technology cannot be realistically expected to
duplicate the trading of every discretionary trader.

Also, for this reason it is very difficult to learn how to trade the
same way someone else does. And it's silly to try and duplicate someone 
else's performance perfectly. Each trader must adapt what they learn to
their own environment...

PS. Private email indicates to me that Mark Brown is a great guy. 
PPS. Now I've really said enough on this topic! Sheesh! What a waste of time!
Apologies... Hopefully this is of benefit to someone.
