How a level is made

How one day of options open interest becomes the next session's levels

The bars illustrate the method. The level lines are the real SPX levels from the Nov 10, 2026 close.
  1. 01

    Open interest at every strike

    After each US close, Owl Mastery reads that day's options open interest for every listed strike. The chart puts calls on the right and puts on the left.

  2. 02

    Turned into gamma exposure

    Each strike's open interest becomes gamma exposure, which measures how much dealer hedging that strike implies. Positive gamma tends to slow price down. Negative gamma can speed it up.

    Positive vs negative gamma
  3. 03

    The levels you trade around

    The largest call and put concentrations become the call wall and put wall. Where net gamma flips sign is the HVL. Add the expected one-day range and you have the levels for the next session.

Frequently asked questions

Is Owl Mastery free?

Yes. Every ticker page, with its daily levels, signals and key stats, is free to read without an account. The full dashboard needs a free account.

When are the levels updated?

Once a day, after each US market close, from that day's options open interest. The levels stay the same until the next close.

Which tickers are covered?

US stocks and indexes with listed options. The indexes are the SPX, NDX, RUT and VIX. A ticker with no options data shows its price and signals without gamma levels.

Is this investment advice?

No. Owl Mastery publishes market information for education. The levels describe where options positioning sits, not where a price will go.
