Not just for options traders
Options mechanics
drive the stock market
Market makers who sell options must hedge their exposure by buying or selling the underlying asset. That hedging activity generates real flows in stocks and ETFs that move price regardless of any fundamental or conventional technical factor.
Knowing the gamma structure, key levels and delta flow in real time allows you to anticipate where the market is likely headed before that move becomes visible on the chart. Not as a prediction — but as an understanding of the mechanism that drives it.
Gamma Flip as dynamic support and resistance
Above the Gamma Flip, dealers buy dips and sell rallies, dampening moves. Below it, they do the opposite — they amplify. The level is not arbitrary: it's where the real market dynamic shifts.
Delta flow moves the underlying
Every time a trader buys puts or calls, the market maker who sells them hedges their delta in the underlying. That accumulated flow is visible in the NDF and typically precedes price moves.
Useful for any trader or investor
It doesn't matter if you trade stocks, ETFs, futures or hold no options position at all. Gamma structure and delta flow give you context on the likely behavior of the market in the current session.

Frequently asked questions
What you need to know
What is Gamma Exposure (GEX)? ▼
GEX measures the net gamma exposure of market makers at each strike in the options chain. Positive GEX means dealers absorb price moves; negative GEX means they amplify them. It is one of the most widely used indicators to anticipate intraday market behavior.
What is Net Delta Flow (NDF)? ▼
NDF measures the net delta accumulated from options hedging activity during the session in real time. When delta flow diverges from price, it signals directional exhaustion before price confirms it — useful for detecting intraday reversals and inflection points.
How frequently is the data updated? ▼
The Live Options Flow Analysis plan updates every 10–15 seconds via ThetaData Terminal. The Advanced Indicators plan updates every 2 minutes with a 15-minute delay on the options chain.
Do I need to trade options for this to be useful? ▼
No. Market maker hedging generates real flows in stocks and ETFs that move price regardless of any conventional technical factor. Understanding gamma structure and delta flow is useful for any trader or investor operating in the U.S. market, regardless of the instrument they use.
What markets does the options chain cover? ▼
The data covers the U.S. options market including SPX, QQQ and individual stocks listed on NYSE and CBOE. Compatible with 0DTE options and multiple simultaneous expirations.
