First backtest I have posted, this site is awesome! Instead of using this strategy w/ individual stocks I chose major market etfs (i.e. spy, dia, qqqq). I changed the long moving average to 100 days from 50, left the short moving average at 10. I added one line that adds commissions per shares traded (not sure how realistic this is, I don't trade in real life) I really like the way this performs during major downturns in SP500.
