ARB drops 10% as Robinhood Chain momentum stalls
Arbitrum (ARB)

Arbitrum’s ARB token fell 10% over 24 hours after its rally stalled near $0.25, according to ambcrypto.com. The price dropped to a low of $0.214 before trading near $0.217 at press time. This reversal tested whether the Robinhood Chain narrative could withstand a broader market sell-off.
Trading volume also fell 31%, pointing to quieter activity during the decline. Coinalyze data showed more than $1.9 million in long liquidations as ARB slipped from $0.25. The DefiLlama chart showed USD Inflows turned negative to -$12.8 million after four consecutive days of positive readings.
Three days earlier, the reading had climbed to $503 million. Derivatives traders were pulling back too, with Open Interest falling 10% to $290 million. Perpetuals sell volume climbed to $112 million while net buying fell to -$249 million.
Despite the sell-off, the Trend Strength Index maintained an upward trajectory and ARB held above its short-term Moving Averages. A move back above $0.24 could put the recent rally back in play. First, bulls would need to defend $0.20, with a loss potentially opening a deeper move toward $0.17.
How the market reacted
Whalio's own Binance spot order flow for ARB, measured when this story was written up on 24 September 2026. Not the outlet's figures.
At $0.2160, ARB shows a 42.5% buy ratio over the last hour, indicating short-term selling pressure. This contrasts with a 51.5% buy ratio over the last four hours, suggesting buying interest is stronger over a slightly longer timeframe. The 24-hour buy ratio sits at 49.6%, showing a near-even split in spot market sentiment. Volume Delta for the hour is -$97,763, meaning more volume was executed at the ask than the bid in that short window. Over four hours, Volume Delta is positive at +$185,041, indicating net buying pressure in that period. The 24-hour Volume Delta is -$540,885, and the CVD for the 24-hour close is -$349,714, confirming that sellers dominated the full day.
The latest daily buy ratio of 52.1% sits at the 85th percentile of the last 323 days, against a median of 49.6% - stronger buying than most days.
Was that an ordinary day?
