Open interest indicator for MetaTrader 5

What the indicator shows

Open interest by strike

Each strike gets a bar whose length is proportional to the number of open contracts. A threshold filter keeps only the levels that matter.

Daily inflows and outflows

Where open interest grew and where it shrank. An inflow line can be extended right to expiration or until price first touches it.

Progress and regress

The indicator follows every large inflow: the position keeps growing, holds, or is being closed.

Call and put walls

The strikes with the largest open interest above and below price, one to five per side.

Open-interest profile

A histogram across all strikes at the right edge of the chart: calls, puts or both.

Total OI and volume

Day-by-day histograms for futures and options, in the chart window or as a separate panel below it.

Why MetaTrader has no open interest

The spot forex market has no single exchange, so a broker's terminal has no exchange open interest. What standard volume indicators show is the number of price changes at your broker, not contracts.

Real open interest exists at CME, where futures and options on the same currencies, gold, oil and indices trade. The exchange publishes it every day after the close. OLIMP parses that report and sends levels to the terminal; on your broker's chart they are aligned with price automatically.

Instruments

Currencies (EUR, GBP, AUD, CAD, CHF, JPY), gold, silver, copper, WTI and Brent crude, natural gas, S&P 500, Nasdaq 100, Dow, Bitcoin and Ether. The instrument is detected from the chart symbol.

Questions and answers

Is the data real-time?

No. CME publishes open interest once a day after the trading day ends. The indicator updates levels once the report is out.

Is there a version for MetaTrader 4 or TradingView?

No, the indicator works only in MetaTrader 5. Current levels can be viewed without installing anything in the Analytics section of the site.

Does it show crypto-exchange open interest?

No. For Bitcoin and Ether it uses CME options and futures, not Binance or Bybit data.

Does it work for stocks?

No. The indicator works with CME products: currencies, metals, energy, indices and crypto.

Will any broker do?

Yes, any broker with MetaTrader 5. Levels are calculated in futures prices and aligned with your broker's price.

What should I read about open interest?

The knowledge base has articles on open-interest flows, option walls, PCR and Max Pain.
