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.
?days=N (1-365) to control window length.
