Quote from Buy1Sell2:
And this is why the experienced human mind is a better trading tool than an automation system. The automation system cannot adapt, it must be rekindled by the human. There are still a lot of people looking for an exact system for an inexact science, thus the number of pages so early in this thread. As I have said before, trading with a chart is like looking at a painting. Is the painting done by Van Gogh or by William Gaines? If it was created by William Gaines or Don Martin, try to stay away. Automation cannot appreciate artistic beauty.

I just disagree.
Trading is not an art but a science. That's why they hire quants and not artists to run trading desks these days.
Program trading accounts for 40% of NYSE volume. You think it's done that way because they lose money doing it? Institutions are also downsizing their trading desks as they automate. The only place I can see intuition playing a role is in the initial brain storming phase of system development.
Without trying to cast stones, I think NoPM's almost immediate abondonment of his rule based methodology merely demonstrates that he is unable to quantify what he is doing and has got caught up in the emotional side of trading. This not only costs money but leaves one unable to adjust the initial approach with any degree of certitude so that it might work in the future.
Sorry if I took the journal a bit off topic but I think it is an important point to consider and understand.

Automation may be ok for institutions because they are cutting labor costs. and feel that smaller gains are ok due to the fact they are not having to pay big salaries. Experienced humans make more money in general.

Quote from mechtrader41:
What i heard from a very serious person was: Never do decisions how to trade if you are in a position, do this stuff before or later.
That`s also a serious theme at Van Tharp and Douglas, they go in the depth of psychological issues, it`s nearly impossible to make good decisions if you are in the emotional stress of beeing in a trade. They describe a lot of human mistakes nearly 100% occuring if you do tradingdecisions in the trade. One simple thing is the lotto effect, cause people own a lottery(paper, bill ?, uuh my english..) they expect this to have an extrem unrealistic high chance of win, same if you are in a position, you are not more able to have a neutral sight of marketaction...your interpretation of your charts/indicators is different if you are in a position. I personally have plenty of psychological issues myself i could not yet master...
Quote from ssternlight:
If experienced humans (read traders) made more money than IB's wouldn't dump them to automate.
I don't really want to take the thread off-topic. I'll agree to disagree with you on this one and if you feel like adding a last post on it that's OK by me.
