Definition. A stacked time series of daily call and put premiums (received and paid) across major exchanges (Deribit, OKX, Binance) for each asset, in USD. The four legs are: Put Premium Received (total earned from selling puts), Put Premium Paid (total spent buying puts), Call Premium Received (total earned from selling calls), and Call Premium Paid (total spent buying calls). Maturities: Weekly (up to 7 days), Short (7 to 30 days), Mid (30 to 90 days), Long (90+ days).

Interpretation. Put premium received often reflects traders selling volatility or expressing a slightly neutral-to-bullish view, as put sellers benefit from stable or rising prices. Put premium paid is typically used as downside protection or to express a bearish outlook. Call premium received indicates neutral-to-bearish sentiment or an attempt to generate yield in a range-bound market by selling volatility. Call premium paid is generally associated with bullish positioning, as traders seek upside exposure with defined risk.
