SPDR S&P 500 ETF (SPY) Gamma Exposure, Call Wall, Put Wall and Dealer Levels
SPY trades the busiest option market on the planet, with expirations every trading day and open interest spread across strikes a dollar apart. That depth is the reason SPY dealer positioning is the single best real-time read on how the broad market is being hedged: there is simply more of it, priced more continuously, than anywhere else. This page computes SPY's call wall, put wall, gamma flip, key gamma strike, max pain and expected range from the live chain each session, then grades how well those levels hold, forward-only, with nothing revised after the close.
As of July 25, 2026, SPY's call wall sits at 740.00 and max pain at 745.00. These update each session.
The rule-based local-trend read resumes at the next market open, once SPY's live price and session reference levels are available.

Today's Volume-Profile & Reference Levels
Tight, tradeable SPY levels from price and volume, where the market actually transacts, as opposed to the dealer-gamma positioning levels above.
The badge on a level is its running accuracy: the share of sessions it was tested in which price respected it (held within tolerance). VWAP, opening range and initial balance carry no badge, they are derived from the same session, so grading them would be circular.
Volume-profile levels appear after the 10:35 ET capture, once a full prior session is available from the live feed.

Why SPY positioning is the cleanest hedging read available
Depth matters more than most explainers admit. On a thinly traded name a single large position can create a wall that means nothing the next morning. On SPY the same strike is being priced continuously by thousands of participants across expirations that land every day of the week, so the concentrations the math finds are the product of real, persistent hedging demand rather than one desk's position. When SPY's call wall sits just overhead, that is a statement about where a very large amount of hedging turns from supportive to restrictive, and it is the reason SPY levels are worth checking even if you never trade the fund itself.
SPY, ES futures and SPX are one market in three wrappers
The three instruments track the same index and their levels translate directly, with SPY trading near one tenth of the index price and ES futures carrying a basis to cash. A SPY call wall therefore marks a price on the ES chart too, which is exactly how we use it: the futures contract sets the trigger and the fund's options are the execution vehicle. If you want the mechanics of that translation spelled out, our ES vs SPX vs SPY comparison and the ES futures versus SPY fund breakdown cover the contract details. This page is the live measurement rather than the explainer.
Same-day expirations concentrate here more than anywhere else
Contracts expiring the same day they are traded make up a large share of SPY volume, and they behave differently from longer-dated positioning. Their gamma is enormous near the money and it evaporates by the close, which is why a SPY level can act like a magnet in the morning and stop mattering by mid-afternoon. Two practical consequences follow. First, the key gamma strike is often the most useful number on this page during the middle of the session, because that is where same-day hedging pulls price back. Second, a break away from it late in the day tends to travel, since the positioning that was holding price in place has already decayed.
How to read the live SPY levels above
Begin with the gamma flip, which tells you which kind of session you are in: above it, dealer hedging leans against the move and ranges compress; below it, hedging follows the move and ranges extend. Then treat the call wall and put wall as the outer references for the day and the key gamma strike as the pull in the middle. The volume-profile figures below the option levels add what the chain cannot see, where volume actually traded, the value area, and the prior-day extremes. Overlaps between an option level and a session reference are the highest-quality prices on the page. For the underlying theory, our complete guide to gamma exposure walks through the calculation step by step.
Methodology and what the published record does and does not say
Levels are marked from the session chain and graded after the close, forward-only, with the rules published and nothing re-marked. Our S&P 500 study, computed from the index chain under those same rules, has the gamma flip holding 81 percent of tested sessions, the call wall 57 percent, the put wall 54 percent, the prior-day high 85 percent, the value-area high 87 percent and the volume point of control 80 percent, across more than 220 graded outcomes. That is the index record and the provenance for the method. The SPY record on this page is separate, it starts empty the day tracking begins, and it will show a building state with a tested-day count until it has enough sessions to be worth quoting. We would rather publish a short honest record than a long invented one.
How to Read These Levels
Think of these as reference levels, prices where buying and selling pressure tends to concentrate, so price often pauses, reverses, or accelerates as it reaches them. They describe where reactions are more likely, not when to buy or sell. The accuracy record on each level shows how often it has actually held once the SPY track record has built up.
Dealer gamma levels, options positioning▾
- Call wall
- The strike above the current price with the heaviest call-side positioning. It often acts as a ceiling, as price rises toward it dealer hedging tends to slow the advance. Watched as resistance and a common upside target.
- Put wall
- The mirror below price: the heaviest put-side strike, where declines tend to stall. Watched as a support area and a place where bounces are more likely.
- Gamma flip
- The price separating a stabilizing environment (above it, hedging dampens moves) from an amplifying one (below it, hedging extends moves). Used as a directional dividing line, calmer above, more volatile below.
- Key gamma strike
- The strike nearest price with the largest total positioning. Acts as an intraday magnet, the price the market is most likely to gravitate back toward. Used as a pin level for mean-reversion.
- Max pain
- The strike where the most option value expires worthless. The theory says price drifts toward it into expiration; whether it actually does is exactly what the forward-only record measures rather than assumes.
- Expected range
- The high-to-low band the options market is implying for the session. The edges work as stretch targets; a close outside the band marks an unusually strong day.
How We Compute and Score
The methodology is fixed and published so the figures are reproducible.
The levels
- Call wall, the strike with the largest call-gamma concentration above spot.
- Put wall, the strike with the largest put-gamma concentration below spot.
- Gamma flip, the price where the running cumulative net gamma crosses zero.
- Key gamma strike, the strike nearest price with the largest total positioning.
- Max pain, the strike where the most option value expires worthless.
- Expected range, a one-session band from at-the-money implied volatility.
Scoring
After the close we read the session high, low and close. A level is tested when price comes within a set tolerance, held when it closes on the expected side, and broke otherwise. Untested days are excluded from the hit-rate denominator, and every percentage is shown next to its tested-day count.
Price tested the level and closed on the expected side — it acted as support or resistance.
Price reached the level and closed decisively through it — the level gave way.
Price never came near the level. Excluded from the hit-rate, so quiet days never inflate it.
The SPY record starts empty and builds forward. Until this symbol has 30 tested sessions, the tool shows a “Building” state with the tested-day count instead of a percentage. We would rather show a short honest record than a long invented one. Our proven methodology on the S&P 500 has the gamma flip holding around 81 percent and the option walls in the mid-50s, and the same rules run on SPY's chain.
Frequently asked questions
- What is SPY gamma exposure?
- It is an estimate of how much dealers must buy or sell to stay hedged as SPY moves. Because SPY carries the deepest option market available, the strikes where that hedging concentrates give an unusually clean read on how the broad market is positioned right now.
- Do SPY gamma levels work on ES futures and SPX?
- They describe the same index, so the levels translate. SPY trades near one tenth of the index price and ES carries a basis to cash, so a SPY call wall marks a corresponding price on the ES chart. Many traders read the levels on one instrument and execute on another.
- Why do same-day expirations matter so much for SPY?
- Contracts expiring the same session hold very large gamma near the money and lose it entirely by the close. That makes the key gamma strike act as a magnet during the day and makes late-session breaks away from it more likely to run, because the positioning holding price in place has already decayed.
- What is SPY max pain?
- The strike where the most option value expires worthless. It is recomputed from SPY's live chain each session. Whether price actually drifts toward it is measured here after the close rather than asserted.
- How accurate are these SPY levels?
- The SPY record accrues forward from the day tracking begins and is shown with its tested-day count. The same methodology applied to the S&P 500 index chain has the gamma flip holding 81 percent and the option walls in the mid-50s across more than 220 graded outcomes.
