PCR Stock Screener: Filter OI and Volume Ratios

What the screener can and cannot rank

Each row describes a stock and the available options inputs for the selected data settings. OI PCR compares outstanding put and call positions; volume PCR compares traded contracts. The two can rank the same stocks differently.

Sentiment and setup labels are classifications generated by the application. A label such as bullish or bearish is not proof that OI belongs to buyers or writers. Inspect the raw values, expiry, quote quality and price context behind it.

1. Expiry and strikes. Keep the expiry and strike coverage comparable across stocks.
2. OI and volume ratios. Outstanding positions and traded volume answer different questions.
3. Derived classifications. Setup and sentiment labels are heuristics, not proof of buying or writing.
4. Open the instrument. Use the row action to inspect the contract rather than relying on the stock label alone.

Build a useful shortlist

1. Choose the available instrument group, expiry and data interval. Verify whether the page is showing a historical preview or live updates.
2. Start with OI PCR or volume PCR and a broad range. Add the second measure only when it serves a separate question.
3. Use symbol search to inspect a known stock, or sort the table to compare available extremes.
4. Read sentiment and setup filters as rule-based labels. Clear them when checking whether a label hides relevant rows.
5. Open the individual option chain and verify strike concentration, liquidity, underlying price and data time before drawing a conclusion.

Worked example: a high ratio from a small denominator

Stock A has put OI 100,000 and call OI 50,000, giving PCR 2.0. Stock B has put OI 1,000 and call OI 100, giving PCR 10.0. Ranking by PCR alone puts B first even though it has far less covered positioning. A large ratio is not a measure of market importance or liquidity.

These figures are illustrative. Compare absolute totals and coverage alongside the ratio, then check whether one strike dominates the result.

Avoid turning a filter into a forecast

Missing rows, changing expiry selection and sparse strikes can alter a shortlist. Ratios from different expiries are not equivalent. Refreshing the page does not guarantee every component quote has the same timestamp. Use the session PCR walkthrough to inspect a candidate in time context.
