What is the Real Time Updates index chart? The Real Time Updates chart shows you the live price for an ETF or index overlaid against nearby key SpotGamma levels. Each of these SpotGamma levels is defined within our knowledge base and can act as a form of resistance, support or create pinning via a magnetic effect as we approach an options expiration. The y-axis reflects the current market price while the x-axis reflects the time over the course of the day. Again, this chart simply provides you with a quick snapshot of where price movement is compared to our key levels. SpotGamma Subscribers can access this chart for the SPX, SPY, NDX, QQQ, RUT and IWM.
