Reading Bitcoin Option Flows, Skew, and Expiry Positioning

Summary

This weekly commentary interprets BTC options activity across several March dates in 2021. It tracks positions rolled from the March expiry into April, including put protection, call spreads, outright calls, and put selling. The author connects these trades with changes in implied volatility and put-call skew, while distinguishing possible protection of long holdings from speculative bearish positioning. The notes also describe call buyers targeting a rally and sellers at higher strikes, potentially for yield or because they doubt the rally’s scale.

The commentary reports that implied volatility initially remained subdued despite sharp spot moves, then moved with expiry-related dynamics and choppy intraday conditions. It observes that heavy put buying after expiry did not necessarily translate into higher near-term skew, since some deep out-of-the-money trades may have limited influence on common skew measures and may be absorbed by market makers. These are interpretations of observed flow, not confirmed trader motives or a systematic signal. The snapshots cover selected trades and market conditions, so they do not establish a repeatable strategy or predictive performance.

Key ideas

• The commentary follows option positions as exposure rolls from March expiries into April and June contracts.
• Put buying may represent hedging by long holders or speculative downside exposure, and flow alone cannot establish intent.
• Put-call skew and implied volatility can move differently from headline option volume.
• Deep out-of-the-money put trades may have limited impact on commonly used skew measures.
• Call activity includes buyers positioning for a rally and sellers targeting higher strikes or yield.
