Has anyone ever heard of this b/4? they say nice things about stockfetcher. they mention stochastic and macd are the 32 best ta indicators.

in regard to their first filter with the naz100, i plugged it in and came up with 96 hits. thanks, that's almost everyone.

any thoughts on their filters?

Yes, but look how restrictive this filter ended up.
Its a more random try/error method. Doesnt follow stock evolution.
I didnt find the filter that well performing in my backtests either.

The idea isnt new - let a dumb machine search for the perfect
technical filter. Is there any? If so, let me know, or post it here...

3/28/2006 3:44:04 AM's funny how complicated some people make trading.

Look at TIE, RACK and HANS..simple Momentum stocks make me lots of $$'s..NO indicators EVER. I think 99.99% of T.A. is a complete waste of time...

Some people spend more time/money and effort trying to "guess" the future. I simply follow and make $$'s. It's your time I guess.

Trading is a science and Art, and because of that there must be human touch in selecting the wining stock.

Therefor i do not think that this software is capable of replacing human mind

Markcrisp, couldn't agree with you more. I have been trading for 15+ years now and tried everything under the sun, including fancy, complicated filters on stockfetcher but my best results come from buying stocks that are strongly trending and making orderly pullbacks towards strongly rising weekly 10 period ema which is in turn above an upsloping weekly 40 period ema. I also want to see steadily rising RS and check IBD to cover the fundamentals. KISS!

Incase you have not already done it you can search this forum for "TAU" and see the discussions he started here and what the results were.

I personally disagreed with his results. He and I sent some emails back and forth for a while and I think he too did not agree that his test supported his claims.


I understand your point about following the trends and agree with it. That is a fine way to make money. But I must say I completly disagree with a statment like "...complete waste of time.." in relation to research new techniques for market prediction (which is the same thing you are doing with trend following by the way). I feel there is much research and discover still to do in the field of computational finance. We have only scratched the surface of what is possible. I also have high hopes for genetic algorythmns, Hidden Markov Models, and the like.

I am now stepping down off soap box ;)

I think Mark's point is you don't have to do anything fancy to make money in the market.

Learning, practicing and mastering the basic fundamentals of trading and money management is all you really need.

On the other hand, using a computer to sift through thousands a stocks decreases the amount of time you have to spend looking for stocks to trade.

So long as you don't confuse stock SELECTION with stock TRADING, you'll be fine.

It only takes ONE STOCK to make you rich if you trade well.

I was not disputing that point. I agree with the philosphy that you don't have to do anything fancy to make money in the stock market.

But from markcrip's post he stated just follow trends like TIE... and make lots of money. TIE has special interest to me in that I too was trading this the first part of the year and exited the stock just before the big gap down (I would call it luck that I got out and nothing else).

On another note "fancy" is higly relative term and I am sure there are many who would believe an Exponetial Moving Average (or maybe RSI is better example :) is fancy and complex. Imagine the arguements when John Murphy first stared doing technical analysis. As you encapsulate and hide this complexity it become considered simple, tride and true. The same is possible with the more complex learning systems.

A more concrete example: Many consider face recognition and background recognition to be far to complex to have everyday usability. Check this out: I have tested it and it works well. It even recognized a picture of Big Ben in the background of an image and put it on the map without being told anything about the image. I personally believe similar things are possible with stocks price/volume pattern. With proper trianing a system should be able to learn that TIE is a failing trend. Maybe there is an indicator (albieit fancy in our current frame of thinking) that can tell you TIE is about to get chopped off at the knees.
