A few assumptions: if any of these strike you as odd or unreasonable, please don't read on.
1. the Perfect System does not exist.
2. some Traders are more Successful than others - why, because they are doing Something right.
3. some Traders are successful Sometimes, but they lack the necessary Concentration & Dedication to create lasting results..
4. regardless scams & rip-offs, a Computer CAN do it better
Is anyone still with me? No objection to (4)? then let us keep going.
In the 1970's Bobby Fischer who was then world chess champion, declared that there is no way a computer can ever beat a grandmaster. Chess requires not just skill & calculation, but also an element of surprise, sacrifice & imagination! Not long ago, the latest Fritz super-computer held the reigning champion Anand to a draw over 3 games .. that means it actually beat him once.*
An element of surprise, sacrifice & imagination! Does this not apply equally to the markets? If you ask me, winning at Forex or other branches of trading is a lot easier than winnning at chess. Even with limited skill & training, you will make the occasional profit. Not so at chess, which takes years of study & practice.
So how come a computer can learn to beat the world champion, but cannot produce consistent results on the markets? Easy: it's all a matter of training, in other words programming. The winning chess computer would have been programmed by grand-masters - result they (the grandmasters) have no hope of beating the world champion, but the computer has learnt enough from them to be able to do it.
Conclusion: all that's required to create the necessary computer program in our line of endeavor, is for several clever people to stick their heads together & along with an expert programmer or two, feed all their clever ideas into it. Remember, there is no limit to what a computer can absorb & calculate.
Let me give a simple example: let us say I 've got something on my charts that produces coloured arrows for up or down. And let us say I do quite well with that, but it's only one of a dozen things I need to actually get a reliable alert. How do I feed that into a computer? Just simply feed the whole system into it, it will be able to use it instantly.
But I've got a dozen such criteria, do I feed them all into the computer? Of course, it can handle a hundred programs in seconds. You can't, the computer can!
Back to the well-intentioned traders who are going to stick their heads together. Myself, I'd be more than happy to co-operate with such a gang of 3 or 4 or 5 or 6 .. trust me, between us, we'd create the super-champ of all times!
