(How to read Quant Data’s Exposure Forecast: the Pin, Grind and Volatile market states, the probability that the state holds, and the GEX levels it draws.)

The Exposure Forecast is a Quant Data tool that looks at the options exposure on a ticker and names the kind of trading day the underlying is in: Pin, Grind or Volatile. A rare fourth label, Transition, covers a session that has not settled into one of the three. Alongside the label, it shows how likely the current market state is to still be in place 30, 60, 90 and 120 minutes later, backed by thousands of data points. It is one of many tools on the Quant Data platform, and this article is Quant Data’s official guide to it.

A Gamma Exposure (GEX) chart aims to show you how dealers are positioned at a single moment. The Exposure Forecast goes one step further: it names the kind of day the session is in and gives you the probability that the environment holds over the next 30 to 120 minutes, instead of leaving you to read a single-day snapshot. It is intended for traders who want to know whether the current state is likely to still be in place before they size a position and place a stop. It does not tell you which way price is going, and it is not a buy or sell signal.

To access the tool, you will want to log in to https://v3.quantdata.us and add the Exposure Forecast to any Built-in or Custom page. If you are unfamiliar with adding tools to a page, I suggest reading this article, which walks through it step by step.

A market state, or market environment, is the current condition of the underlying: consolidating within a range, trending steadily in one direction, or moving sharply in both directions. It’s important to note that market conditions are not static throughout the day, and the underlying can move through more than one state in a single session.

The same setup can be profitable in one session and unprofitable in the next without any change to the setup itself, because the market environment changed. Identifying the market state before entering a position allows you to judge whether the setup is suited to the current conditions, rather than attributing the loss to the setup.

The Exposure Forecast uses four labels. Pin, Grind, and Volatile are the three market states, and Transition is a rare fourth for a session that has not settled into one of them. You may hear these conditions described elsewhere as chop or trend.

A Pin is the Exposure Forecast’s label for a rangebound session. The underlying repeatedly gravitates back toward the same price area and stays within a tight range, so the chart shows compression: limited movement and little net progress on the day. In the image below, QQQ holds a tight range through the afternoon, with the put wall and the call wall drawn as dashed lines.

Pin: QQQ, August 11, 2026, 1:30 PM, a rangebound afternoon

A Grind is the Exposure Forecast’s label for a directional session. The underlying has been trending in one direction, to the upside or to the downside, with brief reversals along the way. On the chart, this appears as a steady grind higher or a steady move lower. In the image below, QQQ grinds higher through the morning, and the climb continues through the afternoon.

Grind: QQQ, June 4, 2026, 1:05 PM, a steady grind higher

Volatile is the Exposure Forecast’s label for a volatile session. Volatility has expanded, and the underlying is moving sharply in both directions across a wide price range, with accelerated moves and quick reversals. In the image below, TSLA spikes, reverses and retests within a wide range around midday. TSLA is shown for illustration.

Volatile: TSLA, July 17, 2026, 12:00 PM, wide swings

Transition is the Exposure Forecast’s label for a session that has not settled into Pin, Grind or Volatile. It is shown in purple in the legend, and it rarely appears on the major index tickers. When it does appear, the panel usually shows no probability, and a blank there should be read as no reading rather than a neutral one. When the label shows Transition, I suggest waiting for the panel to settle into Pin, Grind or Volatile before you use it.

Options exposure reflects the positioning of market makers and dealers, who quote two-sided markets and take the other side of the majority of options trades. To maintain their hedged positions, they buy and sell the underlying as the price moves, and their positioning determines the direction of those hedging flows. When dealers are long gamma, they hedge against the move, selling as the underlying rallies and buying as it drops, which dampens volatility and tends to hold the underlying within a range. When dealers are short gamma, they hedge with the move, buying as the underlying rallies and selling as it drops, which removes liquidity and exacerbates the move.

The Exposure Forecast looks at the options exposure around the current price, weighs it alongside other market factors, and names the kind of day the session is in. That is the “Exposure” in the name. Instead of reading today’s exposure and judging for yourself what it means for the rest of the session, the panel gives you the market state and the probability that accompanies it.

Knowing the market state can affect how you hold a trade, where you place the stop, which position suits the day, and how large to size. A stop that sits comfortably outside the noise in a Pin is likely to be taken out in a Volatile environment, and a position size that is appropriate in a Pin may be too large once volatility expands. The Exposure Forecast will not turn any option strategy into a winner on its own. What it adds is a consistent label for the day and the probability that accompanies it.

Each element of the panel is described below, along with how to use it.

It’s important to note that if part of the panel is blank or shows a dash, the panel has no reading for that element, and a blank should not be read as neutral.

Now that you have a complete understanding of the Exposure Forecast and its capabilities, how can you use it?

Ask what the trade needs from the underlying: to stay pinned, to keep moving, or to continue in one direction. If the current state does not fit that need, wait or change the trade.

Re-check the state after news, and check again before adding to a position. Before the open, the panel still shows the previous session, so wait for today’s label before acting on it. In the image below, you can see the label on SPY move from Grind in the early afternoon to Volatile later in the session.

The label changes during the day: SPY, August 11, 2026, label Grind at 1:30 PM, then Volatile at 3:15 PM

In a Volatile environment, the next hour’s moves have run about twice as wide as in a Pin, so a stop sized for a Pin sits well inside the noise. As a result, on a Volatile day it may be prudent to widen the stop and reduce the number of contracts so that your dollar risk at the stop stays the same.

The state describes the kind of session the underlying is in, not which direction the next move goes. Volatile on a day that is trading down does not mean further downside, and Pin on a day that is trading up does not mean further upside. A Grind has been trending in one direction, but that describes the move so far, not a definitive sign that it continues.

On September 10th, 2026, U.S. oil topped $100 a barrel on concerns that a prolonged war in the Middle East would push inflation back up. Bond yields rose, stocks dropped for a fourth consecutive session, and the S&P 500 closed down a little over half a percent on the day. SPY gapped down at the open and sold off through the first half hour, whipsawed through the rest of the morning, then consolidated within a narrower range through the afternoon and closed down on the day.

Early in the session the Exposure Forecast labeled SPY Volatile with a Strong hold reading, and the label was still Volatile in the afternoon. The forward range it drew was wide, and the underlying stayed inside it. A trader seeing Volatile that early would have widened the stop, reduced the position size, or passed on any trade that needed the underlying to stay pinned.

Use the Exposure Forecast in confluence with the Interval Map, which shows you where exposure is building or unwinding strike by strike, and with Options Exposure, Net Drift, the Options Heat Map and Dark Pool Levels. When the label changes, look at the Interval Map to see which strikes are driving the shift before adjusting a position.

Quant Data’s own testing of the Exposure Forecast on index tickers found the following.

Gamma exposure (GEX) is an estimate of how much market makers and dealers need to buy or sell in the underlying as its price moves, based on the options they are positioned in. Our What is Gamma Exposure (GEX)? article covers it in full; the answers below cover the levels the Exposure Forecast draws and how to carry them over to futures.

The gamma flip, or zero gamma level, is the price at which dealers’ net gamma exposure changes sign, so their hedging flows switch between dampening moves in the underlying and intensifying them. It should be read as a change in hedging behavior rather than as a price target or a level to expect a bounce from.

The call wall is the strike with the largest call exposure, and the put wall is the strike with the largest put exposure. The call wall commonly acts as resistance and the put wall as support, but neither is tied to the current price: after a selloff the put wall can sit above the underlying, and after a rally the call wall can sit below it. Strikes with elevated exposure can act as magnets or areas of rejection; on the panel, read the walls as reference levels and note how far the underlying sits from each, and on which side.

The gamma flip, call wall and put wall are drawn on Quant Data’s Exposure Forecast panel, each with its distance from the underlying. For strike-by-strike detail, open Options Exposure.

Yes, once they are converted. SPX or SPY levels map to ES, and QQQ or NDX levels map to NQ. Multiply the level by the futures price divided by the ETF or index price (for ES from SPY: level × ES ÷ SPY).

Converting a SPY level to ES

The dark pool toggle is off by default. With it switched on, the Exposure Forecast draws the largest dark pool levels near the current price on the price chart as zones. On Quant Data, we sum the dark pool prints at each price level, so a large level marks a price where heavy volume traded off-exchange. Those levels commonly act as support and resistance: the underlying may consolidate or reject at a large level above the current price, and a large level below it can act as support once the underlying turns. Because several levels close in price add up to one larger area, I suggest reading them as zones rather than exact prices. In the image below, SPY bounces off a dark pool zone around midday and keeps returning to it through the afternoon.

Dark pool zones on the Exposure Forecast: SPY, September 10, 2026, 1:30 PM

On the Exposure Forecast, use the dark pool zones in confluence with the call wall, the put wall and the cone. When the edge of the forward range lines up with a dark pool zone, that price is a natural place for a target or a stop, and a zone that sits between the current price and the edge of the forward range is a level to watch on the way, since the underlying may consolidate or reject there. For the full explanation of how the levels are calculated and how traders use them, I suggest reading our Dark Pool Levels article.

The Exposure Forecast labels a trending session Grind and a rangebound one Pin on the ticker you are trading. On a trend day the underlying keeps moving in one direction with brief reversals; on a chop day it keeps returning to the same price area. Neither label is a directional signal.

Neither. A Pin describes a session in which the underlying is consolidating within a tight range; it says nothing about where price goes next.

Yes. The label updates through the session as conditions change, which is why it’s important to re-check it after news and before adding to a position.

The Exposure Forecast runs on the 6,000+ tickers Quant Data covers, from index products such as SPX, SPY and QQQ to single stocks such as TSLA and NVDA.

Yes. SpotGamma, MenthorQ, and Unusual Whales publish gamma levels and related tools; each shows you where the levels sit or what has traded at a point in time. Quant Data’s Exposure Forecast draws the call wall, put wall and zero gamma that level-based tools publish, and adds what a level-only view does not: the market state the session is in and the probability that it holds over the next 30, 60, 90 and 120 minutes, backed by thousands of data points. At the time of writing, we know of no other platform that labels the market state and publishes probabilities that it holds. It also applies the same definitions every session, so a Pin label means the same thing on every day you see it, and it sits alongside the Interval Map, Options Exposure, Net Drift and Dark Pool Levels, so the levels, the flow and the state are in one place. The Exposure Forecast is built by Quant Data and is available only on the Quant Data platform; this article is its official guide.

No. Max pain is the strike at which option holders as a group would lose the most at expiration. Pin risk is the chance that an option you sold is exercised against you (assigned) because price closes right at the strike. A Pin day describes the session, not expiration.

The Exposure Forecast is one way to read the market environment before you size a position and place a stop.
