# 13. Open Interest

Open Interest reflects the total number of active futures contracts on Binance Futures, since the screener operates exclusively on Binance data.

OI is a cumulative metric, meaning its value does not depend on timeframe —

it is identical across all timeframes, because the total number of open contracts is the same at any given moment.\
However, OI Change % is *timeframe-dependent*.

The percentage change is calculated relative to the value from the previous check on the selected timeframe (e.g., previous 1h point, previous 4h point, previous 15m point, etc.).

This allows the screener to track both absolute OI levels and timeframe-specific dynamics.
