Options and Order Flow: Options Flow Is a Different Kind of Data
Order flow exists in options too, but it's a different kind of analysis: instead of a single instrument's footprint you look at flows across thousands of series (strikes and expirations), dealer positioning and their hedging. It's a separate specialisation.
Order flow in this group
Options on the S&P 500 (SPX) and on the ES contract are popular, including same-day expiry options (0DTE). Their volume affects the futures market through dealer hedging.
Options data is real but spread across many series and exchanges, and its interpretation (e.g. dealer gamma exposure) relies on assumptions. I treat it as background, not as a main tool.

Frequently asked questions
Is there order flow in options?
Yes, but in a different form: flows across many series, dealer positioning and hedging. It's a separate specialisation, not a single instrument's footprint.
Do 0DTE options affect futures?
They can, because dealers hedge their positions in futures and stocks. But the strength of that effect is estimated on the basis of assumptions.
Educational content, not investment advice. Exchanges sometimes change contract specifications (tick size, multiplier, hours): check the current specification on the exchange website before trading. The rating concerns suitability for order flow analysis, not profitability. Leveraged futures involve a high risk of losing capital.
