CXO Advisory has just published 20-year results for the SPY:SMA10 strategy (refers to 10-month MA). Compound return 10.1%, SD 10.2, rough Sharpe 0.99, worst drawdown -18%, worst annual return -4.2% (in 2015). No, I can't post it; you have to pay for their site; but you can easily figure this out for yourself. Maybe it's not as consistent as you want. You can try it with a less volatile ETF.
Don't need to pay for this simple test. One can do it and much more for free here.
Here is the result for same strategy from 1990.
