How the market reacted
Whalio's own Binance spot order flow for ADA, measured when this story was written up on 22 September 2026. Not the outlet's figures.
Whalio’s spot data for ADA shows a 1-hour buy ratio of 52.7% and a 4-hour ratio of 49.8%, compared to a 24-hour ratio of 51.0%. The 1-hour volume delta is positive at $135,789, while the 4-hour delta is negative at -$16,093. The buy ratio indicates the proportion of trades executed by buyers versus sellers, with a figure above 50% suggesting more buying activity. The volume delta measures the net value of trades, where a positive number means buyers absorbed more volume than sellers. Current 1-hour buying pressure is stronger than the 4-hour average, though the 24-hour trend remains slightly more balanced with a positive delta of $1,426,431.
The latest daily buy ratio of 45.6% sits at the 5th percentile of the last 322 days, against a median of 49.2% - among the weakest buying days it has had.
