“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: 96%).
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.
Every occurrence
One square per occurrence, oldest first. Green: higher 7 days later. Red: lower. Grey: not yet 7 days old.

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