Options put/call ratio distribution
Where the TAIEX options put/call ratio has sat across the sample the endpoint covers, so today's reading can be placed against it instead of judged on instinct.

Methodology
The daily ratio of put open interest to call open interest is taken across the whole available history, and its percentiles computed from it. Open interest, not volume — they answer different questions and are not interchangeable.
A SHORT sample — 46 trading days, and the row states the count. That is enough to say where today sits among recent days and not enough to call anything historically extreme: a 90th percentile drawn from nine weeks is the highest of about forty-six readings, not a multi-year high. Percentiles describe the sample as it has been; they are not thresholds anyone set in advance. The values are percentage points as the source defines them — 110 means 110%, i.e. rather more puts than calls outstanding.
What this means, and how to use it
The ratio is usually read as a sentiment gauge, and a percentile is what makes that reading meaningful — 'high' means nothing until you know how often it has been higher. With this sample that question is answerable for recent weeks only, which is genuinely useful for 'is today unusual lately' and useless for 'is today unusual historically'. Treat the two as different questions. History, not a forecast, and not investment advice.
