Here is a quick example to illustrate how market gamma may be useful for a futures trader. The last week SpotGamma has calculated a very large amount of gamma in the market, north of $1 billion. That predicts a tight, range-bound market. Below is a chart of the last month, the yellow box highlights a market with very high gamma, and the red box is low to negative gamma. As you can see the yellow box is a tight, mean reverting range. The red box shows large swings. Knowing market gamma may therefore help determine trading levels and pivots for your futures trading.
