Open interest indicator and options chart

Open interest versus volume: count each contract once

One open contract links a long and a short, so 100 open contracts do not mean 200 OI. Volume measures turnover over an interval; OI measures the contracts still outstanding. A contract can change hands repeatedly without increasing OI. CME explains these counting conventions in its volume and open interest definitions.

Each hypothetical row starts separately at 100 OI and assumes no other activity:

For a separate sequential example, start at 100 OI, open 20, close 5 and transfer 8 contracts. Volume is 33 contracts and ending OI is 115. This calculation excludes expiry, exercise and other adjustments. OI is a contract count, not the money paid for those contracts.

TradingView OI: verify the symbol and frequency

1. Open the exchange and derivative contract you intend to study. Add TradingView's built-in Open Interest indicator and read its displayed service symbol.
2. Check the available interval. TradingView documents daily OI for traditional futures and minute intraday OI for supported crypto derivatives. A five-minute price chart does not create five-minute futures OI observations.
3. Check the series units. Keep contract counts separate from coin amounts or currency notional values. A price change can change a currency-denominated value even if the contract count is unchanged.
4. Match exchange, contract month, interval and units before comparisons. Around a futures roll, falling OI in an expiring contract can accompany rising OI in the next contract.

The four price and OI combinations

Compare matching periods of price and contract-count OI. These are descriptive combinations, not trade instructions or measurements of buyer versus seller aggression.

Price and aggregate OI cannot reveal which trades opened or closed, who initiated them, or whether they hedge another position. Flat OI can also hide offsetting openings and closings. CME presents OI as one input used with other analysis in its open interest lesson.

Read this options snapshot within its limits

Enter a stock or ETF ticker, select an available expiration, then choose contract type and strike range and apply the filters. The chart sums returned OI at each strike; the table ranks returned contracts. With 1,200 call OI and 900 put OI, total OI is 2,100 contracts and put/call OI is 0.75. These counts do not reveal the positions' net direction.

• Options come from the Massive snapshot feed through Pineify; the underlying price used for strike filtering comes from FMP. They may represent different update times.
• Massive defines OI at the end of the last trading day. Its daily volume field describes the latest daily bar. An intraday volume-to-OI comparison therefore mixes different observation periods.
• The tool requests at most 250 contracts and does not follow subsequent pages. Expiration choices, totals and rankings cover returned records only; they may omit contracts in a larger chain.
• No historical-date input or OI publication timestamp is displayed. Refreshing retrieves the available snapshot, not historical backfill. For backtests, use observations only from when they were available to the strategy, not an earlier date they describe.
• High OI at a strike does not guarantee support, resistance or an executable fill. Check bid/ask spread, market depth, expiry and contract terms separately.
