Derivatives Market Trends Open Interest Up This is a list of near-month futures contracts where open interest has been added during the current trading day. If there has been a corresponding rise in spot market price on a closing basis, then it is presumed that long positions may have been added in the futures market. Similarly, if there has been a corresponding drop in spot market price on a closing basis, then it is presumed that short positions may have been added in the futures market. Open Interest Down This is a list of near-month futures contracts where open interest has declined because of liquidation of outstanding contracts during the current trading day. If there has been a corresponding rise in spot market price on a closing basis, then it is presumed that participants do not expect the underlying stock to rise much higher and hence may have been liquidating outstanding contracts in the futures market. Similarly, if there has been a corresponding drop in spot market price on a closing basis, then it is presumed that participants do not expect the underlying stock to drop much further and hence may have been liquidating outstanding contracts in the futures market.
