- The total number of outstanding BTC options contracts – or open interest (OI) – increased to $2.10 billion Thursday – just shy of the all-time high of $2.11 billion in late July, per data from Skew.

- On its own, high open interest can indicate existing trends are likely to be sustained – suggesting BTC's recent rally from $10,650 could continue.
- But the number of bearish puts relative to bullish calls has recovered from -10.3% to -3% in the past four days. As the graph below shows – traders are offloading much of their call options onto the market.

- This suggests bullish speculation is beginning to ease – a sign of investors anticipating consolidation or price drop
- Indeed, BTC has already pulled back more than 5% from the 13-month high above $12,400 it reached on Monday.
- Unless buying action comes quick, downwards momentum could push prices down to $11,000, QCP noted earlier this week.
