rather than suggesting a backtest, id request you share any interesting ones youve done in the past.

I have only done one and it was pretty lame: 
  
 1. If spy opens down, buy 
 2. Set a trailing stop loss at some smallish percent (0.5%) 
 3. Sell at the end of the day if you are alive 
 4. (I may have set a percent gain to sell at) 
 5. Do the opposite if it opens up. 
  
 \-&gt; This one crashed and burned hard compared to spy.
