No better than chance13
Once you allow for how many studies were run, a gap this large is luck about 90% of the time, so this signal has told you nothing reliable about the following week.
By holding period
| After | Cases | Higher | Median move | Middle half | Ordinary median | Gap | By luck | Proof score |
|---|---|---|---|---|---|---|---|---|
| 1 day | 21 | 48% | 0.0% | −3.5% to +2.1% | −0.1% | +0.1% | 99% | 11 |
| 3 days | 21 | 43% | −1.6% | −7.5% to +7.0% | −0.5% | −1.1% | 87% | 38 |
| 7 days | 21 | 48% | −2.9% | −7.8% to +11.2% | −1.3% | −1.7% | 90% | 13 |
| 14 days | 21 | 57% | +1.3% | −18.6% to +8.1% | −2.7% | +4.1% | 84% | 40 |

“Ordinary median” is the median move of COTI 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: 60%).
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 12 the gap over 7 days was +1.1%, and in the later 9 it was −1.7%. The direction changed, which is what a pattern produced by chance tends to do.

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

The rule
Daily volume at least 3× its previous 30-day average, and the day closes below its open. A surge of volume on a down day is read two opposite ways: as panic that marks a low, or as distribution before more selling.
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.
