“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: 75%).
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 8 the gap over 7 days was +1.2%, and in the later 6 it was 0.0%. Same direction both times.

The rule
Average trade size in the top 5% of the previous 180 days, with the share of volume from market buys below 50%. When the average trade gets unusually large, bigger players are active. Here they are active while market sells outweigh market buys.
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.
