“Ordinary median” is the median move of SAND 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: 1.2%).

The rule
14-day RSI closes above 70 after being at or below it the day before. An RSI reading over 70 is the most widely quoted "overbought" signal in technical analysis.
Occurrences closer than 7 days to the previous one are not counted again. The signal is confirmed at the daily close (00:00 UTC) and returns are measured from that close. Full method.
