Reposting this here so newer members will see it without having to look it up. Purpose of the Table

This table is designed to show what Market Makers (MMs) need to dynamically hedge the positions they hold on the SPX options chain,
They do so by BUYing or SELLing futures contracts as price moves,
There are 2 major drivers of hedging behaviour: Delta and Gamma (something to read up on, and I have pinned a book that does a good job covering them in detail),

Table Overview

This table is built from SPX options contracts,
Prices under the Strike column are directly from SPX,
ES and SPY are calculations to align with SPX options,
This is done because both are part of the SPX complex, which are designed to maintain confluence with SPX price (slight variances do exist),
ES is based on the front contract price gap to SPX spot price,

Yellow Highlight

We have highlight the closest SPX strike to the current price each time the report generates,
This will give you a visual indication of where we are in relation to the table data,

Delta

The first 4 data columns are derived from Delta Exposure (DEX),
Hedge Flow is the behaviour needed to hedge those positions,
Strength is a rounded down number of DEX on that strike (Red and Green are strong positions, Orange and Yellow are lighter positions),
Net Flow shows us the change in DEX between reporting updates,
Flip tells us when the behaviour has changed between BUY or SELL,

Gamma

The last 4 data columns are derived from Gamma Exposure (GEX),
Pin tells us whether the GEX is short or long, which is a good visual indicator for when gamma hedging behaviour changes,
Strength is similar to DEX (Red and Green are strong positions, Orange and Yellow are lighter positions),
Above / Below are the trickiest columns to understand until you get your head around them,
They both indicate behaviour based on GEX hedging,
Above tells us what the dealers need to do if the options strike is above the current SPX price,
Below tells us what the dealers need to do is the options strike is below the current SPX price,
Being able to see both columns from top to bottom allows us to anticipate changes in hedging behaviour,

There is a lot to unpack on the table, so feel free to ask any questions to you have!

Overnight Futures Hedging by Market Makers – SPX Options Dealers manage delta exposure from open SPX options positions after regular trading hours. How It’s Done: Use S&P 500 futures (ES or MES), which trade nearly 24/5. Delta Hedging Behavior Limitations Dealers Risk Management ETH Hedge Flow Factors 44

Prevents directional risk from overnight price moves in SPX futures.,

Primary trading window is the Globex session (6:00 PM to 9:30 AM ET).,
Dealers adjust hedges if futures move significantly relative to their existing exposure.,

If dealers are short delta and ES futures rise → they buy ES futures.,
If dealers are long delta and ES futures fall → they sell ES futures.,
Activity increases if major gap risk or gamma exposure is present the next day.,

Gamma and vega cannot be directly hedged overnight due to:,
No active SPX options trading.,
No volatility instruments (e.g., VIX futures) adjusting during this window.,

Pre-hedging during the trading day.,
Rebalancing after the market reopens.,

Large open interest near-the-money for the next day.,
Anticipated data events (CPI, Payrolls, Etc) scheduled before the market opens.,
Significant moves in global markets that affect SPX futures.,

Scenario: Price Rises Toward a Strike Where Dealers Are Long Delta This usually means dealers sold calls (or puts below market), making them short the option and therefore long delta. On our table this is expressed in the strength column as a positive value colored as either red for a strong position or orange for a weaker, but still long delta position. As SPX rises toward that strike, the delta of those options increases.

To stay delta-neutral, dealers sell ES futures to offset this growing long delta.,

What happens as SPX approaches the Strike?

Delta Increases Rapidly (high Gamma zone).,
The rate of change of delta (gamma) is highest near-the-money.,
Dealers' hedging demand (selling ES futures) intensifies as price nears the strike.,
Hedging Activity = Selling Pressure,

Dealers must sell ES futures as SPX moves toward the strike.

This creates real sell flows into the market.,
Supply overwhelms demand → price rejects.,

The futures selling (to hedge) can overpower buyer momentum. This often causes the market to stall or reverse near that strike. It looks like a "rejection" — but it's really mechanical hedging flow.

Scenario: Price is Rising into Long Delta, but Gamma is Long Both Above and Below In this setup, SPX is moving up towards a zone where:

Dealers are long delta: which requires selling to hedge which slows things down.,
Dealers are also long gamma: both at the higher strikes (above spot) and lower strikes (below spot).,
On our table, this will present as BUY signals in the Below column both above and below current SPX,
The Above column with show SELL signals,
This configuration sets up a unique, low-volatility dynamic where directional movement is limited, and price becomes increasingly pinned by hedging flows.,

Below Spot: Long Gamma Provides Support

Dealers are long gamma on lower strikes, meaning they hedge against price movement with BUYing into dips.,
As SPX pulls back toward those levels, dealer delta declines — prompting them to buy ES futures to stay delta-neutral.,
This creates a natural bid under the market, absorbing downside pressure.,

Above Spot: Long Delta and Long Gamma Create Soft Resistance

As SPX moves higher into strikes with long delta exposure, dealers must sell ES futures to hedge increasing delta.,
However, because gamma is also long at these upper strikes, this selling pressure is modulated,
If price stalls or reverses slightly, dealers start buying ES again as their delta exposure falls.,
This results in a soft ceiling that doesn’t necessarily produce sharp rejection, but does slow or stall further upside.,

So then what?

Price enters a mean-reverting trap, where dealers are consistently adjusting their hedges against price moves both up and down.,
Upside momentum is capped by dealer selling.,
Downside momentum is cushioned by dealer buying.,

General Outcome

A grind or chop near upper strikes,
Pinning near large open interest levels,
This creates a compressed volatility environment where directional moves are hard to sustain.

Scenario: Price is Rising into Long Delta and Long Gamma, but Below is Neutral Delta and Short Gamma In this setup, SPX is rising into a zone where:

Dealers are long delta: which requires selling to hedge which slows things down.,
Dealers are long gamma at those strikes above: resulting in hedging that dampens price acceleration.,
Below spot, delta exposure is minimal (yellow or orange strength), but gamma is short: meaning hedging behavior becomes self-reinforcing if price begins to fall.,
This structure sets the stage for slower upside with asymmetric downside risk - the trap door effect,

Above Spot: Long Delta + Long Gamma Creates Resistance

As SPX approaches upper long delta-heavy strikes, dealer delta increases and they sell ES futures to stay neutral.,
Because gamma is also long at these levels, the delta increases gradually, and hedging is mean-reverting.,
This limits the potential for sharp rallies and creates a soft ceiling above current price.,

Below Spot: Short Gamma + Low Delta Exposes Downside

Beneath current price, dealers hold short gamma positions but have little delta exposure.,
If SPX begins to fall: Dealers’ delta shifts rapidly due to short gamma.,
They must sell ES futures into the drop, accelerating downside.,
There’s no stabilizing bid from delta hedging or long gamma beneath — so price can break lower quickly.,

What can we expect then?

Price may grind or chop upward, capped by soft resistance from long gamma + long delta.,
Any reversal lower can trigger aggressive hedging flows from dealers, resulting in sharper sell-offs

Scenario: Price is Lowering into Short Delta and Long Gamma, While Above Is Long Delta and Long Gamma In this setup, SPX is declining into a zone where:

Dealers are short delta: requires buying to hedge which slows things down.,
This is represented under the delta strength column in either yellow or green (green being stronger levels).,
Gamma is long in both the zone price is entering and the zone price is coming from.,
This structure is generally supportive and stabilizing, but creates a ceiling above and a apparent floor below.,

Below Spot: Short Delta + Long Gamma Provides Support

As SPX drops into lower strikes delta becomes increasingly short and dealers need to buy ES futures to stay hedged.,
Since gamma is long, this hedging response is mean-reverting and gradual, not aggressive.,
The result is consistent buy pressure on the way down, especially near larger levels.,
Price tends to find support or reverse at these zones.,

Above Spot: Long Delta + Long Gamma Creates Resistance

As SPX approaches upper long delta-heavy strikes, dealer delta increases and they sell ES futures to stay neutral.,
Because gamma is also long at these levels, the delta increases gradually, and hedging is mean-reverting.,
This limits the potential for sharp rallies and creates a soft ceiling above current price.,

What can we expect then?

Dealers are long gamma both above and below spot, which is mean-reverting in both directions.,
Below: strong dealer buying flow supports price.,
Above: dealer selling caps rallies.,
The result is a volatility compression zone, where price may bounce inside a range.,
Breakouts and breakdowns fail unless the market finds a reason.

Discussing 2.5s with GPT

Option Strike Listings,

SPX index options list strikes in 5-point increments as the default.,
Market makers and hedgers frequently interpolate fair values and hedge flows around the midpoint (e.g., between 5320 and 5325).,
This makes the 2.5 level the effective “equilibrium” when hedging or arbitraging between call/put parity.,

Dealer Hedging Flows,

Delta and gamma exposures at each strike often create hedging pressure that peaks or flips around the midpoint between strikes.,
For example, if large open interest is at 5320 and 5325, the hedge flows can cluster near 5322.5, as dealers balance positions.,
This shows up in price action as stickiness or chop around those levels.,

SPY/ES Futures Arbitrage,

SPY ETF trades in $0.01 increments, and ES futures trade in 0.25 increments.,
When mapped back to SPX (10x SPY), this creates natural liquidity bands at 2.5 SPX points.,
Arbitrageurs lean on these micro-levels, reinforcing them in actual SPX price movement.,

Liquidity & Spread Behavior,

Bid/ask spreads in SPX options (especially shorter expiries) often line up more cleanly when SPX is near a 2.5 increment.,
Market makers quote tighter, and more hedging trades go through there, which draws price action toward those levels.,

Psychological & Algorithmic Anchors,

Many trading algos are coded to rebalance or scale in/out at clean increments.,
Since 5-point levels are obvious, the halfway (2.5) level becomes the real battleground where bulls and bears “test” strength before a breakout to the next 5-point strike.,

Bottom line

Every 2.5 SPX level is essentially the “neutral zone” between major 5-point strikes. Because of strike listing mechanics, dealer hedging, and futures/ETF arbitrage, liquidity concentrates there — making those levels disproportionately important in intraday price action.
