Unfilled Gaps from Highs
Wednesday was the first significant day of selling in a while. The gap down in the SPY never filled and the market dropped for most of the day. Below is a study that examines SPY perfromance following other instances of unfilled gaps down from a 50-day high.

Hi Rob,
How are you determining an "unfilled gap" here?
Obviously you weren't looking for an absolute gap outside of the prior day's range, so I can only gather that you were looking at the open compared with the prior close. But if that's the case what makes it unfilled? My data shows the SPY high @ 129.54 compared with the prior day's close @ 129.52, so the opening gap from the prior day's close would have been filled during the day????
What am I missing here?
Hi Graeme,
I used Tradestation for the study. They show $129.50 as the high - just below the previous day's close.
Rob
thanks for the clarification Rob!
Cheers
