What is the Equity Hub Synthetic OI (Open Interest) Model? Equity Hub is where you can analyze how options impact 3,500+ stocks, indices, and ETFs. Within Equity Hub, you can pinpoint when and where options are driving stock prices using SpotGamma’s own proprietary metrics and models. This can help you get ahead of price movement, identify entry & exit price points, and understand where volatility may appear in the names you follow. The Synthetic OI Model enhances SpotGamma’s existing equities model, delivering more precise tracking of short-term options-driven hedging flows across major U.S. indices and all U.S. stocks. This model enhances data precision by eliminating assumptions and categorizing transactions based on multiple new data feeds and proprietary SpotGamma algorithms. The data powering the Synthetic OI Model updates every trading day before the market open. With the prevalence of 0DTE options in the market, the Synthetic OI Model can be more meaningful than the Total OI lens. The positions shown by the Synthetic OI Model tend to remain key points of interest for intraday trading. This model also introduces two new key levels for each: the High Volatility Point holds the most negative gamma, and the Low Volatility Point holds the most positive gamma.
