Since 2018, Cardano has shown a 15% drop in a day 14 times. In the 14 cases old enough to score, the price was higher 7 days later 64% of the time, with a median move of +2.7%. On an ordinary day the median 7-day move for ADA is −0.8%.

There is a gap, but once you allow for how many studies were run, a gap this large is luck about 70% of the time, so it should not be relied on.
By holding period
| After | Cases | Higher | Median move | Middle half | Ordinary median | Gap | By luck | Proof score |
|---|---|---|---|---|---|---|---|---|
| 1 day | 14 | 71% | +3.9% | 0.0% to +9.1% | −0.1% | +4.0% | 2.1% | 87 |
| 3 days | 14 | 57% | +3.2% | −7.7% to +14.0% | −0.3% | +3.4% | 39% | 19 |
| 7 days | 14 | 64% | +2.7% | −6.0% to +10.9% | −0.8% | +3.6% | 70% | 39 |
| 14 days | 14 | 50% | +1.4% | −12.9% to +17.3% | −1.1% | +2.5% | 93% | 11 |
| 30 days | 14 | 36% | −2.3% | −5.7% to +4.9% | −3.1% | +0.8% | 98% | 8 |
“Ordinary median” is the median move of ADA 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: 26%).
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 +3.6%, and in the later 6 it was +3.7%. Same direction both times.

The rule
Close at least 15% below the close one day 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.
