The Open Interest Chain Explorer is where you can go to easily track which options chains or tickers had the most carryover from the prior day’s volume to the current day’s open interest. The first tab, Chain OI Change, tracks the biggest open interest changes by total amount and percentage change on a contract. 

The Ticker OI Change tab shows the same, but is inclusive of all available options chains for each respective ticker. So this page will show which tickers have had the largest change in OI from the previous close.
