“Ordinary median” is the median move of JST 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: 2.5%).
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 9 the gap over 7 days was +9.6%, and in the later 7 it was +5.0%. Same direction both times.

The rule
14-day RSI closes below 30 after being at or above it the day before. An RSI reading under 30 is the most widely quoted "oversold" 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.
