How the market reacted
Whalio's own Binance spot order flow for ATOM, measured when this story was written up on 31 August 2026. Not the outlet's figures.
ATOM trades at $1.46 with a 1-hour buy ratio of 21.7%, indicating weak immediate buying pressure compared to the 4-hour ratio of 55.6%. The 24-hour buy ratio sits at 44.5%, suggesting that while buying interest exists, it is not dominant over selling pressure. Volume delta shows -$79,964 in the last hour and -$139,925 over 24 hours, meaning more money flowed out than in. The CVD for the 24-hour close is -$112,543, confirming net selling pressure. Only 11 of 24 hours saw net buying, with spot volume reaching $1,301,775 across 12,163 trades.
The latest daily buy ratio of 44.7% sits at the 9th percentile of the last 322 days, against a median of 49.8% - among the weakest buying days it has had.
Twenty-four hours later
What ATOM did over the 23 hours after the story broke. The market moves for its own reasons; this is what happened, not what the story caused.
Was that an ordinary day?
The same Binance spot measurements for ATOM, averaged over the days leading up to the story.
Over the preceding week, the 7-day average buy ratio was 50.5%, making the current 24-hour ratio of 44.5% slightly below average by 6.0 points. Volume was 0.60x the average, indicating significantly lower trading activity than usual. The price dropped 9.0% over 8 days, with volume delta totaling +$224,563 for the week. This day is unusual due to the combination of below-average volume and a buy ratio lower than the weekly norm.
