Every flip we have recorded, and what the price did next.

Flips counted: 4 of 5 means four of the five flips are old enough for that many days to have passed. Each median uses only those; with an even number of flips it is the lower of the two middle results.

Range of the median: worked out from the flips' own results, with no assumptions about them. The share in brackets is how often a range built this way holds the true median; with fewer than 6 flips it runs from the lowest result to the highest.

Ordinary days: the median of the same number of ordinary days from the same period lands in this range 95 times in 100. A median is called within the range of ordinary days unless it falls outside it. About 1 cell in 20 falls outside by chance alone.

The latest 25 flips are too recent for some of the columns: each median uses only the flips whose window has passed.

Prices are 4-hour closes on Bitstamp. Returns are measured from the close of the flip candle.

A flip counts as reversed when the next flip came within 3 candles, 12 hours. A flip is only counted once 3 candles have closed after it.

There is less than a year of flips here, too little to count flips a year.

On 4-hour candles the line flips often, and nearly every flip is reversed within 30 days, so the 7-, 30- and 90-day columns mostly show where the market drifted, not what the flip did.
