Round-number levels
Why do traders watch prices that end in zeroes, and what does the data actually prove about them?
In plain words
Round-number levels are prices ending in zeroes, the kind quoted in whole hundreds or thousands, that many traders watch together because they are easy to remember. They are conventions of shared attention, not fixed rules, and they carry no force unless orders actually gather there.
Why it matters
If enough stop and target orders sit near a round price, a market approaching it can stall, slice through quickly, or turn back. Because traders place orders at such marks, the mark can become self-fulfilling, but that has to be shown across many crossings, not assumed from one touch.
In a real week: ETH, week of 4 December 2023
In the week of 4 December 2023, ETH opened at 2192.96, just under the round mark of two thousand two hundred, and rose 7.27% to close at 2352.39. The weekly high of 2403.0 came on Saturday at 08:00 UTC, just above the round mark of two thousand four hundred. The weekly low of 2188.33 came on Tuesday at 07:00 UTC, close to the same lower mark, while volume ran 1.74 times its prior 12-week average.
A common mistake
Seeing round numbers everywhere after the fact. Prices pass through many whole numbers in any week; showing that a specific mark mattered requires comparing many crossings against similar prices that are not round.
