What a round trip costs

At each token’s cheapest pool in each reading: what buying the token costs plus what selling those tokens costs, both priced on the same reading of the pool, fees and price impact included. The median, in basis points: 1 bp is 0.01%, so 10 bp on $10,000 is $10.

Lowest first, by the last 7 days. The last three columns split those 7 days by what the US market was doing, in New York time, as in the cost index: open (9:30 to 16:00 on the days it is open, to 13:00 on its early-close days), closed (the other weekday hours, holidays included) and the weekend. Only pools whose own price moved count, as in the cost index. A dash: fewer than half of our readings had a number, or fewer than 20 did. Over 1,000: a round trip of this size would lose more than a tenth of the money in the pools we read.

How much could be sold

How many dollars of the token could be sold into the pools we read before its price falls 1, 2, 5 or 10%: each token’s counted pools together, the median of our readings.

Largest first, by the last 7 days. Dollar coins count as one dollar.
