bitcoinethereumnews.com reports that Jupiter’s Ultra trading service generated far fewer sandwich attacks than some competing Solana dApps, according to a new three-year academic study. This finding points to Jupiter’s pursuit of safer trade execution. However, JUP fell more than 9% from its latest high, following a sharp decline. The study highlights a contrast between improved execution safety and recent price weakness.
How the market reacted
Whalio's own Binance spot order flow for JUP, measured when this story was written up on 29 September 2026. Not the outlet's figures.
JUP is trading at $0.3277 with a 1-hour buy ratio of 52.0%, indicating short-term buying pressure is currently dominant. However, this momentum is fading over longer timeframes, as the 4-hour buy ratio drops to 40.9% and the 24-hour ratio settles at 48.1%. The volume delta shows a net outflow of -$401,582 over the last day, meaning sellers have outweighed buyers significantly in that period. While the last hour saw a small net inflow of +$2,578, the broader 24-hour trend is clearly bearish with a CVD of -$401,582. This suggests that while there is brief interest, the overall flow is driven by selling pressure.
The latest daily buy ratio of 47.7% sits at the 39th percentile of the last 322 days, against a median of 48.7% - ordinary for this coin.
Was that an ordinary day?
The same Binance spot measurements for JUP, averaged over the days leading up to the story.
Over the preceding week, JUP saw a price increase of 9.7% despite a total volume delta of -$2,864,993. The current 24-hour spot volume of $10,598,450 is 1.54 times the weekly average, indicating unusually high activity compared to the prior seven days. However, only 2 of the past 7 days showed net buying, suggesting this is not an ordinary day for accumulation. The recent price gain occurred alongside a negative volume delta, highlighting a divergence between price action and actual buy pressure. This week's activity contrasts with the current 24-hour net outflow, showing a shift from weekly selling pressure to current high-volume trading.
