What is open interest in crypto?
Open interest (OI) is the total number of outstanding derivative contracts — such as perpetual futures or options — that have not yet been settled or closed.
Think of it as a measure of how much money is actively positioned in the derivatives market. Every open position (one long + one short) counts as one unit of open interest.

How Open Interest Works
open_interest_changes_based_on created_or_closed_label or :
brand_new_contract_is_created
the_old_buyer_position_transfers
both_sides_of_an_existing
Key point: Open interest only changes when new contracts are created or existing contracts are fully closed. Simply transferring a position from one trader to another doesn't change OI.
How to Interpret Open Interest
The most powerful insights come from analysing open interest alongside price action:
| Price | Open Interest | Signal |
|---|---|---|
| rising | oi_rising_price | Strong Bullish |
| oi_rising_volume | falling | Weakening Rally |
| oi_falling_price | oi_rising_sentiment | Strong Bearish |
| oi_falling_volume | oi_falling_sentiment | Weakening Selloff |
Open Interest vs Volume
These two metrics are often confused but measure very different things:
| Feature | Open Interest | Volume |
|---|---|---|
| What it measures | Total active contracts right now | Total contracts traded in a period |
| resets | no_cumulative | yes_resets_each_period_24h |
| indicates | Market participation & conviction | Activity & liquidity level |
| when_high | Many positions at stake | Heavy trading activity |
| Best used for | Trend strength confirmation | Identifying breakout potential |
Pro tip: The strongest signals come when both open interest and volume are rising together in the same direction as price. This indicates high conviction with active participation.

Frequently Asked Questions
What is open interest in crypto?
Open interest (OI) is the total number of outstanding derivative contracts (such as futures or options) that have not been settled. It represents the total number of active positions in the market at any given time.
What does rising open interest mean?
Rising open interest means new money is entering the market — new positions are being opened. When combined with a rising price, it signals a strong bullish trend. When combined with a falling price, it signals a strong bearish trend.
What does declining open interest mean?
Declining open interest means positions are being closed — money is leaving the market. This often signals that a current trend is losing momentum and may be nearing a reversal or consolidation phase.
Is high open interest bullish or bearish?
High open interest alone is neither bullish nor bearish — it simply indicates strong market participation. The direction of the price movement alongside open interest changes is what matters. Rising OI + rising price = bullish. Rising OI + falling price = bearish.
What is the difference between open interest and volume?
Volume measures the total number of contracts traded in a given period (e.g., 24 hours), while open interest measures the total number of contracts currently open. Volume resets each period; open interest is cumulative. High volume with high OI indicates strong conviction.
Can open interest predict liquidations?
Indirectly, yes. Very high open interest with heavy leverage concentration at certain price levels can signal potential liquidation cascades. When many leveraged positions are clustered near a price level, a move through that level can trigger mass liquidations.

Derivatives & Leveraged Products — Important Risk Warning
Derivatives are complex financial instruments that carry a high risk of rapid capital loss. Leveraged trading (futures, perpetual contracts, margin trading, options) can result in losses that exceed your initial investment. The majority of retail investor accounts lose money when trading derivatives.
You should carefully consider whether you understand how derivatives work and whether you can afford to take the high risk of losing your money. This content is for educational purposes only and does not constitute financial advice, investment advice, or a recommendation to trade derivatives.
In the European Union, crypto derivatives are classified as financial instruments under MiFID II. Only platforms with appropriate MiFID II authorization may offer these products to EU residents. Regulatory treatment varies by jurisdiction — verify the legal status of derivatives trading in your country before participating.
