I've been sort of doing the following (paper trading) with moderate success. it is too simple though so would love any insights or extensions.... Main idea: only trade QLD or QID (why sepnd time looking for individual stocks ?) 5 minute bars FOR QLD sma(8)>sma(20) go long QLD Same idea for QID Exit when sma(8)<sma(20) Could have QLD(sma(8))>QLD(sma(20)) and then wait for QID(sma(8))<QID(sma(20)) for confirmation-or something like that. There appear to be a few whipsaws but overall not too bad.
I don't want to be sound harsh but trading is a solo sport. If you have found something that you think works, you need to test it yourself and eventually trade it and see if it works. That's not exactly something that a public forum might help you with. Of course, besides backtesting you also need to make sure that your system makes sense. Considering yours is a very simple (which is great!) trend following system, I see nothing wrong with it. I think you're on the right track but from here on you are mostly on your own. Good luck! (although luck isn't exactly a significant factor in trading)
