# 未平仓量 ## Definition Open interest is defined as the number of open positions (including both long and short positions) currently on a derivative exchange's BTC/USD trading pairs. ## Interpretation A large value of open interest can indicate increased **volatility** in the price of BTC. For this reason, an open interest chart could also be useful for determining the market tops and bottoms with additional indicators. ## Use Case ### Statistical Correlation Analysis to Volatility We find that open interest (independent variable) and volatility (response variable) are statistically in **positive correlation** where p-values of F-statistic (for linear model) and the slope are less than 0.001. R-square of the model is estimated as 0.36 where the value is reasonably high considering financial raw data. ![](/files/-MCBUg6ooEjgEGsdPI3O) The settings for this experiment are the followings: * We consider date range from '2018-11-05' to '2020-06-01'. * We resample the data in 15 days to compute volatility. * Volatility is computed as subtraction of max to min value of every resampled window. * Values in the above chart are in log form. ## Link to Our Data * [Open Interest in CryptoQuant Live Chart](https://cryptoquant.com/overview?search=open+interest) * [Open Interest in CryptoQuant Data API docs](https://cryptoquant.com/docs/#operation/getOpenInterest) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
