Why Trading Volume and Open Interest Matter to Options Traders

An increase in open interest simply signifies new money coming into the market, but it does not reveal whether the new money is bullish or bearish. Large blocks of new contracts being opened can result in a sharp increase in open interest, indicating a strong level of interest in a particular asset or market. As previously mentioned, open interest is significantly influenced by the creation of new trades and the closing of existing ones.

For example, imagine one trader holds 10 option contracts and sells them to a new trader entering the market. The transfer of these contracts does not create any change in the open interest because positions were transferred, not closed or opened.
