“Ordinary median” is the median move of SEI 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: 80%).

The rule

50-day moving average closes above the 200-day moving average after being below it. The 50-day average crossing above the 200-day average is one of the most publicised bullish signals in any market.

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.
