Perpetual swap analytics for funding, OI, and price dynamics.

Basis in basis points measures the relative premium or discount of the derivative against its reference market.

This makes it a core signal for carry, positioning pressure, and cross-market dislocations.

Mark-Price Spread in basis points shows the gap between the exchange mark and the traded market price on a relative scale.

The spread matters because mark prices influence liquidation engines, risk controls, and PnL calculations even when the last trade wanders.

Mean Basis summarizes the average premium or discount sustained through the interval rather than at a single moment.

That makes it helpful for distinguishing persistent carry conditions from brief spikes or flickers.

Basis Std Dev in basis points measures how unstable the relative pricing relationship was inside the bar.

A high reading suggests basis was moving around materially, which can complicate hedging and carry strategies.

This metric tracks the variability of the mark-price gap, not just its average level.

That distinction matters because some markets spend long periods close to fair value but occasionally experience sharp internal repricing.

Funding Rate is the clearest running price of directional crowding in perpetual futures markets.

Positive rates usually mean longs are paying shorts to hold exposure, while negative rates imply the opposite.

Funding Rate Update Frequency tells you how often the venue refreshed its funding observations during the interval.

Operational details like this matter because faster or noisier update cadence can affect how traders interpret prediction signals.

Open Interest tracks the total outstanding derivatives exposure and serves as the balance-sheet backdrop for price action.

Rising open interest means new positions are being opened or expanded, while falling open interest suggests risk is being reduced or closed out.

Open Interest % Change shows how quickly positioning expanded or contracted over the interval.

This is often more informative than the raw level because it makes sudden positioning events immediately visible.

Open Interest Volatility measures how unstable outstanding positioning was inside the bar.

High values can indicate frequent leverage adjustments, position recycling, or stress-driven churn rather than steady accumulation.

OI/Price Change Ratio compares how much positioning changed relative to the magnitude of the price move.

It helps answer whether price action was accompanied by substantial leverage participation or happened mostly without new positioning.

Mark Price is the exchange reference price used for risk, liquidation, and many internal controls.

It often matters more than the last traded print when you care about margin behavior or the true state of the derivatives venue.

Index Price represents the external reference basket that the derivative is ultimately trying to track.

It provides the cleanest anchor for judging whether the contract is rich, cheap, or simply reacting to the broader market.

Last Price % Change gives the immediate traded move seen by market participants on the venue.

It is the most reactive of the price-change measures and therefore tends to pick up local bursts before slower references catch up.

This ratio compares how quickly the mark price moved relative to the underlying index reference.

Values above or below one indicate that the venue mark is leading or lagging the external market move.

Mark/Last % Change Ratio compares the stability-focused mark with the more reactive last trade.

When the two diverge meaningfully, the venue is effectively saying that the latest print should not be taken fully at face value for risk purposes.
