There is a noteworthy situation in the SPX options market. The options contracts expiring tomorrow morning have accumulated a significant open interest at the key level of 7,000. These monthly expiration dates often bring market volatility, especially when a particular strike price gathers a large number of open contracts. Traders are closely watching whether this level can hold or if it will serve as support/resistance for tomorrow's market movement. This type of data is very helpful in understanding institutional trends.
