One of our proprietary market options gamma indicators is our “Combo Strike™” series. These indicators are based derived through a combination of SPX and SPY options levels. Each day we normalize this combined price to produce a key SPX strike level, as shown below its 3042. If you are an ES futures trader we then further adjust this combo strike to match the ES futures contract. In this case the Sep ES contract is about 12 points below SPX Index prices. You can see how the market pegs that exact level on the retest.
