Harmony’s native token ONE delivered one of the most volatile performances in the altcoin market on September 17, 2026. Earlier in the day, ONE surged 9.83% within 15 minutes to $0.00153, with 24-hour trading volume reaching $18,252,609.92 and a 24-hour gain of 127.34%.
The rally extended through the session, with ONE establishing an intraday high of $0.002367. However, the momentum reversed sharply later: the token fell 10.65% in 15 minutes to $0.002115, even as its 24-hour gain stood at 163.72%. Trading volume climbed to $37,631,885.21, indicating intense speculative activity.
Traders noted that no single confirmed catalyst triggered the reversal, suggesting that profit-taking after the rapid advance and broader mixed market sentiment played key roles. The day’s trading range spanned from $0.000657 to $0.002367, underscoring extreme volatility.
Key levels to watch include resistance near $0.0024 and support around $0.0016. A break below support could lead to further weakness, while a rebound above resistance may signal renewed buying interest.
