Put/call ratio
OI-weighted put/call ratio - the most-asked-for single sentiment indicator from options data. PCR > 1 means more put OI than call OI (typically defensive / fear bid); PCR < 1 means call-heavy (typically risk-on). Two granularities:
  • ?granularity=intraday - rolling intraday series, refreshed every 30s. Use for live dashboards.
  • ?granularity=daily - one value per UTC day, sourced from the historical store. Use for time-series studies and backtests.
Filter the daily mode with ?days=N (1–365) to control window length.
