Another principle for you:
There is no best system, any more than there is a best car. There might, however, be a best car for you.
I suggest you forego trying to find a best, or even "reasonable" system until you come to terms with how you like to trade. Start your system design by looking within yourself:
1. define what kind of trading performance you want
2. determine how much time and energy you are willing to invest
3. realize that psychological tendencies may interfere with executing signals
4. spend some time looking over lots of charts to see the kinds of things to expect
5. look at the daily performance graph of the system to see if you can stand the ride.
