Which one fits you
You want GEX levels on a chart without paying: Obelion's free pages show net gamma by strike, the call and put walls and the zero gamma level for each ticker, updated through the session.
You trade SPX and want daily written analysis: SpotGamma is built around research notes and index models, and it charges for that depth.
You follow unusual options activity first and gamma second: Unusual Whales is a flow tool that also shows gamma.
You already live in TradingView and want levels drawn there: MenthorQ's integrations are the point of the product.
We make Obelion, so weigh our view accordingly. The comparison above uses only facts each company publishes.
What to check in any GEX tool
Data freshness: open interest updates once a day, so intraday GEX shifts come from price moving through strikes. Ask how often the chart refreshes during the session.
Method: GEX rests on an assumption about which side dealers hold. Good tools publish how they compute it. Ours is on the methodology page.
Coverage: index-only tools miss single stocks where gamma squeezes happen. Check that your tickers are covered before you pay.
