Taking advantage of market data can help traders anticipate where a trade may go. This video discusses the interaction between SPX index options expiration and S&P 500 futures. The SPX options open interest tonight may dictate how futures trade at the open in the morning on Friday. As off-the-floor traders in our HFT chatroom, we use this data to trade the S&P emini futures during the opening hour. The data from OCC shows huge open interest at 1275.00 strike on SPX January options. Meanwhile, the S&P cash closed at 1280. There is a 5 point spread that's expected tomorrow morning for the market open.
