How Does the Concept of ‘Open Interest’ in Derivatives Compare to the ‘K’ Value in a Liquidity Pool?

'Open interest' in derivatives is the total number of outstanding contracts that have not been closed or exercised. It measures market participation and liquidity in the derivatives market.

'k' in a liquidity pool (x y = k) is the constant product of reserves, measuring the total capital depth available for trading. Both metrics indicate the overall liquidity and robustness of their respective markets.
