Optimism (OP)

trendkia.com reports that Bitcoin has advanced above $86,000, marking a 6.33% gain for September and defying typical late-summer market sluggishness. The cryptocurrency posted a 42.71% increase for the third quarter, its strongest performance since 2017 and the top quarterly result since the fourth quarter of 2024. Historical data from 2013 indicates that positive Septembers are often followed by double-digit October surges, fueling interest in the Uptober phenomenon.
US spot exchange-traded funds attracted $51.25 million in net allocations through Thursday, potentially securing a third consecutive week of inflows. Corporate treasury expansion continued as Strategy, led by Michael Saylor, purchased 1,665 Bitcoin, bringing its total holdings to 847,666 tokens valued at approximately $6.02 billion. Despite this strength, Nexo Dispatch analyst Iliya Kalchev noted that debt dynamics and monetary policy signals are transmitting complicated impulses across the digital asset spectrum.
He observed that sustainable bullish momentum requires a calmer interest rate environment, accelerated ETF participation, and continuous absorption from long-term holders. The Core Personal Consumption Expenditures index moderated to 3% year-over-year, yet the 10-year US Treasury yield rose to 5.29% and the US Dollar Index climbed to 101.5. K33 Research highlighted that Bitcoin absorbed substantial derivatives deleveraging without severe price deterioration, with open interest contracting by 49,028 tokens over seven days.
This positioning flush was driven by organized profit-taking rather than aggressive spot distribution, leaving little fuel for cascading long liquidations. Bitcoin is currently pressing into resistance at the 50% Fibonacci retracement level of $87,599, with the weekly RSI registering around 62. Live metrics show Bitcoin trading at $86,402, up 1.82% from its prior session close of $84,853.
How the market reacted
Whalio's own Binance spot order flow for OP, measured when this story was written up on 2 October 2026. Not the outlet's figures.
Optimism is trading at $0.1281 with a 1-hour buy ratio of 53.8%, indicating short-term buyer dominance, while the 4-hour ratio sits lower at 47.8%. Over the full day, the buy ratio drops to 46.7%, suggesting that buying pressure is fading as the session progresses. The 1-hour volume delta is positive at +$29,419, showing immediate net inflows, but the 4-hour delta is negative at -$41,920. This shift into negative territory over longer timeframes results in a 24-hour volume delta of -$640,719, meaning sellers have overwhelmed buyers over the day. Cumulative Volume Delta closed at +$100,326, indicating that despite the daily net outflow, the total volume of buy orders exceeded sell orders throughout the period. Spot volume for the day reached $9,639,742 across 59,551 trades, with net buying occurring in 14 of the 24 hours.
The latest daily buy ratio of 49.5% sits at the 41st percentile of the last 322 days, against a median of 50.1% - ordinary for this coin.
Was that an ordinary day?
The same Binance spot measurements for OP, averaged over the days leading up to the story.
Comparing today's 24-hour buy ratio of 46.7% against the preceding week's 7-day average of 50.2% reveals a 3.5 percentage point decline in buying sentiment. This dip aligns with the weekly volume delta of -$185,268, confirming that selling pressure has been the dominant force over the longer timeframe. While the 24-hour spot volume of $9,639,742 represents 1.21 times the average daily volume, the price has still declined by 2.5% over the eight-day period. Only five of the past seven days saw net buying, contrasting with today's 14 hours of net buying activity. This suggests that while today has seen a relative increase in buying hours compared to the weekly norm, the overall weekly trend remains bearish with negative volume deltas.
