There is a gap, but once you allow for how many studies were run, a gap this large is luck about 80% of the time, so it should not be relied on.

“Ordinary median” is the median move of ARKM over the same number of days starting from any day. “Gap” is the signal's median minus the ordinary one. “By luck” is how often a gap at least that large comes from randomly chosen days, corrected for the 3,572 studies run at each holding period (for this study taken alone: 40%).
Holding it for 7 days
Dips and best points use each day's low and high, measured from the close on the signal day. Costs assume 0.3% for a round trip: a 0.1% exchange fee each way and 0.05% slippage each way.
Did it hold up over time?
Splitting the cases by date: in the earlier 18 the gap over 7 days was −1.7%, and in the later 13 it was −3.4%. Same direction both times.
