...the reason I recommend weekly backtesting is that it reveals how the parameters are shifting with volatility increases, which according to my testing we are experiencing now. I will look forward with great anticipation to learning how your system development goes. If you read Schwager's Wizards books, you may recall that in one interview (I forget which) the trader said something to the effect that "There are about 20 simple but highly profitable patterns out there that if they were generally known, their edge would vanish instantly. Look for them. You'll find them."
That's why you keep your mouth shut when you find something good. Of the systems I currently trade, one is so good I can't believe it, and it's also trivially simple. Just because you're a po' boy and an amateur doesn't mean that you can't find something big if you keep at it. Then one way or another you can scrape up the cash to trade it to its limits. IMO a really good system can grow a small account at 200-400% a year. Of course there are all sorts of personal issues that you have to deal with along the way, and portfolio-management-like issues to learn how to handle. Good fortune to you.
