open_interest

Open Interest

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_pct_change

Open Interest % Change

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

Open Interest Volatility

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

OI/Price Change Ratio

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.
