Arbitrum (ARB)

Tradersunion.com reports that Arbitrum (ARB) fell 10.36% to $0.1515 as active selling resumed despite recent ecosystem growth. The decline occurred even as high-profile integrations and renewed activity fueled bullish sentiment, with the drop reinforced by overbought signals near key resistance. Robinhood Chain, powered by Arbitrum technology, introduced a revenue-sharing stream directing funds to the Arbitrum DAO treasury, helping the platform become the third largest by revenue.
However, competition remains high as Robinhood Chain achieved significantly higher fee levels. Regulatory scrutiny increased when the Arbitrum Watchdog Committee initiated actions that could result in permanent funding bans for three projects accused of misusing grant funds. Additionally, a legal dispute with Gerstein Harrow LLP blocked the recovery of 30,766 ETH after a hack.
Technical indicators show ARB trading above its 20-day, 50-day, and 200-day moving averages, reinforcing a short-term uptrend. The RSI sat at 71.223 in overbought territory, while the CCI reading was 131.5679, suggesting near-term upside may be capped. Intraday volatility stood at 7.44% after a downside gap of about 2.43% at the open. Analysts noted that persistent selling raises the risk of further downside despite increased ecosystem funding.
How the market reacted
Whalio's own Binance spot order flow for ARB, measured when this story was written up on 9 September 2026. Not the outlet's figures.
Whalio data shows ARB trading at $0.1650 with a 1-hour buy ratio of 48.1% and a 4-hour buy ratio of 51.4%, compared to a 24-hour buy ratio of 50.5%. The 1-hour volume delta is -$141,278, indicating net selling pressure in the short term, while the 4-hour delta is +$318,754, showing net buying over a longer timeframe. The 24-hour volume delta is +$322,046, suggesting that buying pressure has been dominant over the full day despite the recent intraday dip. A buy ratio above 50% indicates that more volume is being absorbed by buyers than sellers, while a negative volume delta means sell orders have exceeded buy orders in value for that period. The 24-hour spot volume was $32,588,854 across 164,300 trades, with net buying occurring in 10 of the last 24 hours. This mix suggests that while the broader daily trend remains bullish, immediate short-term momentum has shifted toward sellers.
The latest daily buy ratio of 46.4% sits at the 8th percentile of the last 324 days, against a median of 49.6% - among the weakest buying days it has had.
