There are thousands of websites and companies offering trading systems with seemingly fantastic profit opportunities. None of these are real. For two reasons:
1). If you discovered how to make geese lay golden eggs, would you really tell anyone?
2). The market is, in mathematical terms, a Complex Adaptive System (CAS) (see Wiki) which means that if anyone starts making excessive profits then the market will adapt. In a nutshell, if you find that buying IBM at the open consistently makes profit, then before long the people from whom you bought the shares will stop selling them to you because they consistently make a loss.
Thus the only way ahead is:
Option 1. Insider knowledge/other illegal means
Option 2. Practice discretionary/intuitive trading until you develop sufficient expertise to be able to compete (est 10,000 – 15,000 hours work – see Matthew Syed’s book, Bounce). I actually think it would be quicker to become a golf pro or tennis pro.
Option 3. Develop your own trading ideas and test them (using Excel). Creativity and original thought are already there as part of the brain's toolbox. Using these tools you can compete without getting a science PhD or spending 15,000 hours watching charts.
So what should you do?
1. Think of a novel idea.
2. Test it to see if it works (I use Excel to test trading ideas/strategies). If it doesn't, go back to step 1.
3. Paper trade it to check you haven’t made a mistake.
4. Start live trading small amounts to check it works in real life.
5. Gradually increase your position size.
6. Provided that your position size remains a tiny portion of total market volume, then you can avoid the feedback loops inherent in Complex Adaptive Systems (see next page). So, keep it small – trade multiple stocks/futures (which will provide some robustness anyway) and don’t tell anyone else what you’re doing!
