What Is Open Interest in Crypto? Reading Squeezes and Liquidations
Education only. Not financial advice. Trading derivatives carries a high risk of loss.
Short answer
Open interest is the total notional value of all outstanding derivatives positions that have not been settled or closed. A squeeze is a fast price move driven by forced closing of leveraged positions. When shorts are forced to buy back, it is a short squeeze, and when longs are forced to sell, it is a long squeeze.
What is open interest in crypto, and what is a squeeze? Open interest tells you how much money is sitting in open leveraged positions. A squeeze is what happens when that leverage gets forced out all at once. Reading the two together shows who is in control of a move, and how fragile it is.

What is open interest?
Open interest is the total notional value of all outstanding derivatives positions in a market that have not been settled or closed. It is a count of what is still open, not what has been traded. A position is added to open interest when a new buyer and a new seller open a contract, and it comes out when a position is closed.
| Open interest | Volume | |
|---|---|---|
| What it measures | How much is still open, at a point in time | How much has been traded over a period |
| What changes it | Positions being opened or closed | Every trade |
| What it tells you | The size of the crowd’s open bets | Whether a move has activity behind it. Volume spikes during price moves confirm the move, and volume without a price change suggests indecision |
Open interest and price: the four combinations
Open interest on its own is a size. Read it against price and it shows the crowd’s real position. Harmonic’s weekly briefs use these four readings.
| Price | Open interest | What it may suggest |
|---|---|---|
| Rising | Rising | Fresh longs are opening. New money is entering the trend |
| Falling | Falling | Longs are capitulating. Positions are being unwound and leverage is leaving |
| Falling | Rising | Fresh shorts are opening |
| Rising | Falling | Shorts are covering |
Pair the reading with funding. In Module 2, the build-up before the May 2021 crash had funding above 0.05% per 8-hour period for weeks, open interest at all-time highs and longs dominant. Our guide to perpetual futures and funding rates explains the funding side.
What is a squeeze in crypto?
A squeeze is a fast move in price driven by forced closing of leveraged positions. It is not a view about value. It happens because a position gets closed whether or not the trader wants it closed.
- Short squeeze. The price rises, and shorts are forced to buy back the asset they bet against, at a loss, right into a rising market. That forced buying pushes the price higher, which forces the next round of shorts to cover too, and the whole move feeds on itself.
- Long squeeze. The mirror image. The price falls, leveraged longs are forced to sell, the forced selling pushes the price lower, and more longs are forced out. Harmonic’s Lesson 1, how to read the market after a liquidation cascade, covers it. A cascade is a self-reinforcing chain reaction where a price drop forces automatic closures of leveraged positions.
Both depend on the same mechanics. A liquidation is the automatic, forced closure of a leveraged position when the account balance falls to the maintenance margin level. There is no warning call, and the position closes at whatever the market price is at that moment. Our guide to margin, liquidation and risk management explains how to calculate your own liquidation price.
Liquidations by side
The side that gets liquidated tells you which kind of squeeze it was. Forced-out longs and forced-out shorts mean opposite things, so Harmonic’s weekly briefs read liquidations by side. Two real, dated examples from the briefs show both directions.
Example from Harmonic’s August 24, 2026 Opener
A short squeeze. The Treasury raised the ceiling on its long-end bond buybacks by $2 billion per operation, a dollar amount that barely registers in the bond market. What moved markets was the signal underneath it: the Treasury Secretary said he believes long-term yields are priced wrong, and that the Treasury is willing to act on it.
- On August 19, $2.739 billion in short positions were forced closed in a single day.
- Thursday added $671 million, and Friday another $1.265 billion.
- Across the three days, shorts lost roughly $4.68 billion, the biggest stretch of forced short covering ever recorded.
Bitcoin funds also took in money for five straight days alongside the squeeze, so the shorts that bet wrong were forced out while institutional money came in behind them.
Example from Harmonic’s August 28, 2026 Closer
The reverse, at a smaller scale. On August 28, a Fed chair signal deflated part of that rally. That day’s liquidation total came to $480.6 million, and 75.4% of it hit longs, about $362.2 million. That is roughly 13% of what shorts lost on August 19 alone. Bitcoin took the largest hit at $188.2 million, and Ethereum was next at $107.9 million.
Same direction reversed, nowhere near the same scale. The size of the liquidations matters as much as the side.
Example from Harmonic’s Lesson 1
A long squeeze. Bitcoin had run to an all-time high above $126,000, and open interest was near record levels. A 100% tariff announcement on all Chinese imports hit during a weekend session when liquidity was thin. In 24 hours, $19.3 billion in positions were liquidated, the largest single-day forced-selling event in crypto history, and over 1.6 million accounts were liquidated. Bitcoin fell from $122,000 to $104,782.
The lesson’s point is that a crowded long market produces a cascade that is almost entirely long liquidations.
How to monitor these signals
- Open interest against price. Check the direction of both, using the four combinations above.
- Funding. High positive funding means longs are paying heavily to hold, which signals a crowded market.
- Liquidations already realized. Note which side got forced out, and how large the total was. After a cascade, a meaningful drop in open interest confirms the forced selling has been removed.
- Liquidations still ahead. A liquidation heatmap shows where large clusters of leveraged positions would be forced to close if price reaches certain levels. Those clusters can act as price magnets.
- The long-to-short ratio. It shows which side the crowd is leaning toward.
Module 2’s checklist before any trade says to look at open interest direction, the long-to-short ratio and recent liquidation clusters near the current price, using a market data site such as CoinGlass. Harmonic’s weekly briefs also carry a Hyperliquid positioning and liquidations table in every issue. It shows the backdrop, which is open interest against price, the change in open interest, and liquidations split into longs and shorts. The lessons, the live lesson tools and the core curriculum are part of Harmonic Academy, along with the weekly briefs.
On Hyperliquid, WTI crude open interest jumped 18% to $220M as price fell, a sign of fresh shorts. Bitcoin saw the biggest liquidations, $16.22M of longs and $14.10M of shorts.

Hyperliquid is a different exchange from the prices above, so its numbers will not match them exactly. Nasdaq 100 and S&P 500 are the indexes that QQQ and SPY track. Hyperliquid lists the indexes themselves and has no QQQ or SPY market.
Open interest is the number of contracts still open, measured in contracts so price moves do not distort it. Volume is the dollar value of all trades over the same window, estimated from Hyperliquid’s one-minute price data. A backdrop needs price and open interest to each move 0.5% or more: open interest up with price down is fresh shorts opening, both down is longs giving up, open interest down with price up is shorts covering, and smaller moves read flat. A liquidation is a position an exchange force-closes because the trader can no longer cover the losses. Longs liquidated are traders betting on a rise who were forced out as price fell, and shorts liquidated are the reverse.
In this capture from the November 2 Opener, WTI crude open interest rose 18.16% to $220 million as price fell, which the table reads as fresh shorts opening. Silver’s open interest fell 10.38%, which it reads as shorts covering. Bitcoin saw the biggest liquidations, $16.22 million of longs and $14.10 million of shorts.
Limits of these signals
These signals are context, not predictions. High open interest and heavy funding show that a market is fragile, not when it will break. In Module 2’s words about funding, a high reading is often a precursor to a sharp reversal, not because funding causes the reversal, but because it signals the degree of over-leverage that makes a cascade possible.
- Size and side both matter. The same direction of liquidations at a fraction of the scale did not trigger a cascade.
- A squeeze can run on a signal. The August squeeze came from a Treasury signal, not from the size of the intervention. The trigger is often a headline you cannot predict.
Frequently asked questions
What is open interest in crypto?
Open interest is the total notional value of all outstanding derivatives positions in a market that have not been settled or closed. It shows how much money is committed to open positions at a point in time. Rising open interest alongside rising prices indicates new money entering, and falling open interest with falling prices indicates de-leveraging.
What is the difference between open interest and volume?
Volume is how much has been traded over a period. Open interest is how much is still open at a point in time. Volume counts every trade, while open interest only changes when positions are opened or closed.
What does rising open interest mean?
Rising open interest means more positions are being opened than closed, which usually means new money is entering the market. Read it together with price. Rising open interest with rising price suggests fresh longs, and rising open interest with falling price suggests fresh shorts.
What is a short squeeze in crypto?
A short squeeze happens when a price rise forces short sellers to buy back the asset they bet against, at a loss. That forced buying pushes the price higher, which forces the next round of shorts to cover, and the move feeds on itself. In August 2026, shorts lost roughly $4.68 billion over three days in the largest short liquidation event in crypto’s history.
What is a long squeeze?
A long squeeze is the mirror image. A price drop forces leveraged longs to close, the forced selling pushes the price lower, and that forces more longs out. Harmonic’s lessons call the chain reaction a liquidation cascade.
Where can I see crypto liquidation data?
Market data sites publish liquidations and open interest, and Harmonic’s Module 2 points to CoinGlass for open interest direction, the long and short ratio, and liquidation clusters. Exchanges also show their own data. Harmonic’s Weekly Brief reports liquidations by side and open interest every week.
