No better than chance20
Once you allow for how many studies were run, a gap this large is luck about 97% 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 | 101 | 47% | −0.5% | −3.3% to +3.3% | −0.1% | −0.4% | 53% | 23 |
| 3 days | 101 | 44% | −1.1% | −6.4% to +5.6% | −0.4% | −0.8% | 56% | 48 |
| 7 days | 101 | 48% | −0.9% | −9.0% to +11.2% | −1.0% | +0.1% | 97% | 20 |
| 14 days | 101 | 45% | −1.9% | −11.1% to +13.7% | −1.8% | 0.0% | 100% | 20 |
| 30 days | 101 | 49% | −1.7% | −19.3% to +13.7% | −3.6% | +1.9% | 89% | 22 |
“Ordinary median” is the median move of ETC 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: 84%).
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 60 the gap over 7 days was +1.5%, and in the later 41 it was −0.9%. The direction changed, which is what a pattern produced by chance tends to do.
Every occurrence
One square per occurrence, oldest first. Green: higher 7 days later. Red: lower. Grey: not yet 7 days old.

The rule
Close at least 10% above the close 3 days earlier.
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.
