We look at the performance of the overnight session when the S&P 500 opens at a 5-day low but at the same time, the close is higher than the open.
We backtest the following trading rules:
SPY must open at a 5 day low.
The close must be higher than the open.
If 1 and 2 are true, then enter on the close.
Exit tomorrow’s open.
Test period from 2005 until July 2013. Below is the profit curve.
