OI shows where positions remain open by strike and expiry; IV shows the volatility level embedded in an option’s price; skew compares IV across puts and calls; and max pain is a conditional expiry calculation based on current OI. Read all four with the venue, instrument, expiry, units and timestamp visible.
What each metric actually tells you
These metrics answer different questions. Combining them is more informative than watching any one chart:
As an Amazon Associate I earn from qualifying purchases.
| Metric | What it measures | What it does not establish |
|---|---|---|
| Open interest | Contracts or notional still open at a strike and expiry | Whether the open positions are net long or short, who holds them, or where Bitcoin must trade |
| Implied volatility | The volatility level implied by an option’s market price under a pricing model | The direction of Bitcoin’s next move |
| Risk reversal/skew | The relative IV of a call and put at a specified delta | A guarantee that downside or upside will occur |
| Max pain | The candidate expiry price that minimizes aggregate intrinsic value owed to option buyers, using current OI | A target that market makers will force or that Bitcoin will reach |
A dashboard number without these qualifications is incomplete. Always record the venue, the underlying (spot-linked Bitcoin or an option on Bitcoin futures), expiry date and time, strike or delta, call/put side, unit, data timestamp and calculation method.
How to read open interest
OI versus volume
Open interest is the total size of positions that remain open for an instrument or group of instruments. Trading volume counts contracts traded during a period, including contracts that were subsequently closed. A contract can therefore add to volume without increasing end-of-day OI. Conversely, a large OI number can remain even when today’s volume is modest.

Deribit’s metrics documentation makes this distinction explicit: OI concerns positions currently open, while volume records trading activity. Use OI to study outstanding exposure and volume to study recent turnover; do not substitute one for the other.
Read one expiry at a time
- Select the expiry. Do not combine weekly, monthly and quarterly contracts in one mental total. Each expiry has its own time horizon and payoff.
- Plot calls and puts by strike. Note where the largest bars sit relative to the current Bitcoin price.
- Check the unit. A display may use contracts, underlying Bitcoin units or dollar notional. Deribit describes metrics displays that can show both contract totals and dollar notional, so two charts labelled “OI” can have different scales.
- Write down the timestamp. OI changes whenever positions are opened, closed, exercised or expire.
Large OI at a strike means many positions remain open there. It does not tell you whether buyers are long calls, sellers are short calls, or participants are using spreads that make the single strike only one leg of a larger strategy. Exchange-level OI also cannot reveal each holder’s objective, hedge or ability to influence the spot market.
What an OI shape can and cannot suggest
A concentration of call OI above spot can be consistent with upside hedges, covered-call supply, speculative calls or multi-leg spreads. Put OI below spot can represent protective puts, short-put income trades or part of a spread. The same bar can therefore have opposite interpretations depending on who is long and who is short.
OI is more useful when you compare it with changes in OI, traded volume, price, IV and the order book. For example, rising OI alongside rising option prices may indicate new risk is being added, but without trade-level buyer/seller information it still does not identify the net direction of that risk. Treat narratives such as “call walls” or “put support” as hypotheses to test, not facts proved by OI alone.
Reading an OI chart in practice
A repeatable six-step scan
- Identify the contract. Confirm whether the option references spot Bitcoin, a Bitcoin future or another underlying, and note the quote and contract multiplier.
- Choose one expiry. Record its exact date and settlement time, not merely “March” or “30 days.”
- Align the price scale. Mark the current underlying price and identify in-the-money and out-of-the-money strikes.
- Separate calls from puts. Use separate colors or panels; a combined total can hide opposite exposures.
- Normalize units. Convert contract counts to underlying units or notional only if the multiplier and currency are known. Never compare raw contract counts across venues with different contract specifications.
- Compare with time and activity. Save the reading, then check how OI, volume, IV and spot changed at the next observation.
Questions to write beside every chart
- Is this live order-book data, an exchange settlement or a derived series?
- Is OI measured in contracts, Bitcoin units or dollars?
- Are calls and puts displayed separately?
- Does the chart include every strike or only selected strikes?
- Could a low-liquidity or interpolated value be affecting the display?
Implied volatility: compare like with like
What IV is
Implied volatility is the volatility input that makes a pricing model reproduce an option’s observed market price, after accounting for variables such as strike, time to expiry, rates, carry and the underlying price. It is a price-derived expectation of future variability under that model, not a direct forecast of whether Bitcoin rises or falls.
An IV quote is meaningful only with its context. State all of the following when you record or compare it:
- Venue and underlying: options on spot-linked instruments are not automatically comparable with options on futures.
- Expiry or tenor: a single-expiry quote and a constant-maturity 30-day index measure different things.
- Strike or delta: IV usually varies across the strike surface. A 25-delta put is not the same observation as an at-the-money option.
- Option side: identify call or put.
- Timestamp and source: live quotes, settlement marks and derived curves can differ.
Why a “30-day IV” is not every option’s IV
CME’s Bitcoin volatility benchmark page describes BVX as a once-per-second, 30-day constant-maturity measure built from Bitcoin and Micro Bitcoin options order-book data. BVXS is a daily settlement measure. These indexes summarize a defined tenor and methodology; they are not the IV of every listed expiry or strike. A 30-day benchmark can be compared with another 30-day benchmark only when the underlying, venue and methodology are also aligned.

Risk reversal and call-put skew
CME defines a 25-delta risk reversal as:
25-delta risk reversal = 25-delta call IV − 25-delta put IV
Under that convention, a negative result means the put IV is higher than the call IV. Traders often describe this as richer pricing for downside protection. It is a relative-pricing observation, not proof that Bitcoin will decline. A positive result means the specified call IV is higher; it still does not establish a bullish outcome.
Do not compare a 25-delta risk reversal with an at-the-money skew measure or with a put-call IV difference calculated at a different expiry. Delta itself changes with price, time and volatility, so the two options must be identified at the same observation time and on the same surface.
Historical IV and OI figures: how to use dated examples
The following numbers are historical context from CME Group’s analysis published February 24, 2026. The chart data is stated as of February 13, 2026, and must not be read as a live market quote.

| 25-delta Bitcoin call IV | 75% | February 5, 2026; CME Group analysis |

| Difference using CME’s risk-reversal convention | -20 percentage points | 75% minus 95%; indicates higher put IV in that snapshot |
| Average put IV during 2025 | 46% | Historical average reported by CME; not a current reading |
| March-expiry call OI | $660 million | Snapshot dated February 13, 2026 |
| March-expiry put OI | $240 million | Snapshot dated February 13, 2026 |
| Call-to-put OI ratio | Approximately 3:1 | Calculated from those notional figures; OI alone does not identify strategy direction |
The call-heavy March snapshot can be consistent with positioning for recovery, as CME discussed, but the ratio does not prove that all call holders are bullish or that the market will rally. It is a dated notional comparison, not a current signal.
Derived volatility curves and benchmark methodology
Check how a curve was constructed
CME’s QuikVol FAQ says its derived curves use CME settlement and SPAN data. When OI is low or absent for an expiry, the displayed curve may be linearly interpolated from expiries with actual derived curves. An interpolated point can be useful for a continuous surface, but it is not the same as a directly observed, liquid quote for that expiry.
Before treating a curve as market evidence, check whether each point is observed or derived, what settlement time is used, and how stale or missing inputs are handled. This is especially important around short-dated expiries, where a small number of trades can move a quoted IV substantially.

Volatility indexes have their own rules
CME’s CVOL methodology version 1.7, dated December 8, 2025, describes broad-based volatility-index weights based on dollar vega OI. Its current-day IV calculations use OI and vega inputs from the most recent five prior end-of-day files. Those methodological choices affect what the index represents and mean that an index level should not be assumed to equal a simple average of the IVs visible on a retail options chain.

The definition
For one expiry, max pain is the candidate settlement price at which option buyers, considered as a group, would receive the smallest aggregate intrinsic value from the currently open options. Deribit’s educational definition describes it as the price level where option holders as a whole would suffer the maximum financial pain.
The calculation
Collect current call and put OI for every strike in the selected expiry. For each candidate settlement price S, calculate:
call payoff = max(S − strike, 0) × call OIput payoff = max(strike − S, 0) × put OIaggregate payoff = sum of all call and put payoffs
The candidate S with the lowest aggregate payoff is the max-pain estimate. Apply the correct contract multiplier and currency before comparing values. If OI is shown as dollar notional rather than contracts, do not multiply it again by the underlying price or multiplier.
A simple illustrative example
Suppose an expiry has calls and puts at strikes 90,000, 95,000 and 100,000. To test a candidate settlement of 95,000, calls below 95,000 have intrinsic value, puts above 95,000 have intrinsic value, and options at 95,000 expire with zero intrinsic value. Repeat that payoff calculation for each candidate strike (and, if desired, intermediate prices). The lowest total is the estimate for that snapshot.
This example is only a demonstration of the method; it is not a market reading. Real calculations need the complete strike set, exact OI units, contract specifications and a clearly stated timestamp.

Recalculate when the inputs change
Max pain is conditional on the OI snapshot and the chosen expiry. New trades, closing trades, rolls, exercises and changes in the underlying can alter the result. Calculate each expiry separately, label the timestamp, and avoid presenting a single “Bitcoin max pain” number without its date.
Why max pain is not a price target
- It uses open interest, not trader intent. The calculation does not know which side of each contract is economically long or short.
- It ignores the path to expiry. Intraday hedging, liquidations, funding, news and spot flows can dominate before settlement.
- It is not a market-maker promise. The arithmetic identifies a minimum aggregate buyer payoff under assumed settlement prices; it does not show that anyone can or will force Bitcoin there.
- It excludes many real-world details. Fees, spreads, early exercise where applicable, cash-versus-physical settlement, hedges in other instruments and multi-leg positions are not captured by a simple OI payoff sum.
Use max pain as a scenario calculation: “Given this OI snapshot, which candidate price minimizes listed-option intrinsic value?” Do not convert it into “Bitcoin will settle at this price.” The reviewed material provides no evidence that max pain predicts eventual settlement.

CME’s Bitcoin futures-options FAQ says daily out-of-the-money option settlements are determined by CME staff using market activity and implied-volatility skews together with futures settlement. In-the-money options are settled using put-call parity with cost of carry. The FAQ states that final settlement is based on the CME CF Bitcoin Reference Rate.
Those rules make CME futures options different from options on another venue or from spot-linked contracts. When comparing an OI wall, IV or max-pain result across platforms, first confirm:
| Comparison item | Why it changes interpretation |
|---|---|
| Underlying instrument | Spot-linked options and futures options have different carry, settlement and hedge relationships. |
| Expiry date and time | “Monthly” or “weekly” labels can conceal different remaining durations and settlement clocks. |
| Strike or delta | IV varies across the surface; equal strike names do not mean equal moneyness. |
| OI unit | Contract counts, Bitcoin units and dollar notional are not interchangeable. |
| Data source | Live order books, exchange settlements and interpolated curves can show different values. |
| Volatility-index tenor | A 30-day constant-maturity index cannot be read as a quote for a particular listed expiry. |
| Publication frequency | Once-per-second, intraday, daily settlement and end-of-day series answer different timing questions. |
A practical workflow for reading a dashboard
- Start with the instrument header. Record venue, underlying, quote currency, contract multiplier and settlement convention.
- Freeze the observation time. Save the timestamp and distinguish live, settlement and delayed data.
- Map OI. For the expiry you care about, list call and put OI by strike and verify the unit.
- Locate spot and futures. Use the same underlying reference that the option uses; do not compare a futures-option chain with an unrelated spot price.
- Read the IV surface. Compare the same expiry, delta or strike and side. Note whether values are quoted or derived.
- Calculate skew. If using the 25-delta risk-reversal convention, subtract put IV from call IV and keep the sign.
- Calculate max pain separately. Use the selected expiry’s complete OI and contract specifications; label the result as a snapshot.
- Check changes. Compare the saved observation with later OI, volume, IV and price rather than interpreting one screenshot as a trend.
- Write a qualified conclusion. Describe positioning and relative pricing, then state what remains unknown about direction, intent and future settlement.
Common reading errors and fixes
Calling OI “buying pressure”
Error: Assuming more call OI means buyers are bullish. Fix: State only that more call positions remain open, then look for strategy, trade and hedge context that OI alone cannot provide.
Mixing contracts and dollars
Error: Comparing a contract-count chart with a dollar-notional chart. Fix: Convert using the documented multiplier or keep the datasets separate.

Comparing unlike IVs
Error: Comparing a 30-day index with a single-strike option expiring in 90 days. Fix: Match venue, underlying, tenor, strike or delta and call/put side.
Treating negative skew as a directional forecast
Error: Reading a negative 25-delta risk reversal as proof of a coming decline. Fix: Say that puts have higher IV under the stated convention; direction is not established.
Publishing a stale max-pain number
Error: Quoting yesterday’s calculation as today’s target. Fix: Include the OI timestamp, expiry and data source, and recalculate when positions change.
Assuming every curve point is directly traded
Error: Treating an interpolated value as a liquid market quote. Fix: Read the provider’s methodology and identify missing-data or interpolation rules.

Using an API or a spreadsheet for repeatable calculations
For a reproducible process, export the selected expiry’s strike, call OI, put OI, contract multiplier and timestamp. A spreadsheet can implement the payoff formulas row by row for each candidate settlement price. Keep the original raw fields beside the calculation so a later reader can audit units and missing strikes.
Deribit has published an educational Python max-pain tool that retrieves option OI through its API and calculates the result for a selected expiry. Whether you use that approach or a spreadsheet, validate that the API response distinguishes calls from puts, returns the intended expiry, and reports OI in the unit your formula expects. A script that silently mixes expiries or notional conventions can produce a precise-looking but invalid number.
How to report a defensible interpretation
A useful dashboard note can fit in four sentences:
- Identify the venue, underlying, expiry and timestamp.
- Describe the largest call and put OI concentrations, including units.
- Report IV and skew with the exact delta or tenor and the convention used.
- Give max pain as a conditional calculation and list the main unknowns: net positioning, hedges, liquidity and future OI changes.
For example, a properly qualified statement would say that a particular expiry has more displayed call notional than put notional at a stated timestamp, that 25-delta put IV exceeds call IV under CME’s risk-reversal convention, and that the calculated max-pain price is the minimum-payoff point for that OI snapshot. It would not claim that calls guarantee a rally, that skew guarantees a fall or that max pain predicts settlement.
Bottom line
Read Bitcoin options in layers. OI maps outstanding positions by strike and expiry, but not their economic direction. IV compares the price of volatility only when venue, tenor, strike or delta and option side match. A negative 25-delta risk reversal means puts are priced at higher IV under CME’s convention, not that Bitcoin must fall. Max pain is a conditional payoff calculation that changes with OI and says nothing certain about where Bitcoin will settle. Keep the units, instrument, methodology and timestamp attached to every number, and the dashboard becomes a measurement tool rather than a source of unsupported forecasts.
