Inside day after earnings is one of my favorite trade.
Most stocks have much higher volatility on their earnings day and it creates lots of trading opportunities for short-term to mid-term trading.
The philosophy of inside bar is about "neutral","choppy","wait","rest","digest", so an inside day after earnings is like the market still tries hard to figure out the earnings report.
Therefore, when the other day the market is able to break either side, it's worth participating as there are many better analysts making their final decisions.
The trade is to put a buy stop 1 cent higher the inside day high and put a sell stop 1 cent lower the inside day low, which means when it breaks to the upside first we long; when it breaks to the downside we short.
I don't really suggest to trade this Sprint while it a good example for this trade today, let's see which way it breaks and how it goes!
