0DTE, 1DTE, or ALL: Choosing the Right Horizon
0DTE, 1DTE, or ALL completely change what you see in the GammaContext suite for NinjaTrader 8. How to pick the right horizon for how you trade.

The GammaContext Gex Panel rolls up your market context into three cards: Regime, Bias, and Space. How to read them in NinjaTrader 8 before every entry.
Published by Cristian Ibáñez
A levels trader asks three questions before every entry. What regime is the market in? Which way is options positioning leaning? How close am I to a key level? The GammaContext Gex Panel answers all three in a single floating window inside NinjaTrader 8, as part of the GammaContext suite for NinjaTrader 8. You don't have to hunt each one down separately.
This guide covers the panel's three cards: Regime, Bias, and Space.
The Regime card shows whether the market sits in positive or negative gamma right now. Alongside that, it shows total Net GEX. It also shows the distance in points to the Gamma Flip. It's the same read you already know from the dashboard, summarized into one card. It doesn't require you to hunt down the Flip line on the chart to confirm it.
According to CME Group (2026), aggregate market gamma exposure describes the direction dealers adjust their hedging in. That direction is exactly what the Regime card rolls up into a single glance.
According to CFA Institute (2026), recognizing a risk regime change early allows for timely repositioning. The alternative is trading off a framework that no longer fits. The Regime card is built for exactly that fast confirmation, before every decision.

The Bias card shows the dominance between call pressure and put pressure in current options positioning. It doesn't tell you whether the market is going up or down. It tells you which way options flow is leaning right now.
This type of read has a well-known basis in options analysis. According to Investopedia, the ratio between put and call volume is a sentiment indicator. A reading skewed toward puts often reflects hedging or caution. One skewed toward calls often reflects bullish directional appetite. This card applies that same dominance logic, updated live, directly on the asset you're trading.
For example, imagine you open NinjaTrader mid-morning. The first card shows positive gamma. Net GEX sits at 85K. Price is twelve points from the Flip. The second card shows call dominance: 62% versus 38% for puts. The third shows spot at 21,368. There are fifty-two points to the Call Wall above. There are ninety-eight points to the Put Wall below.
With those three reads together, in ten seconds you have the full context. A stable positive gamma regime. A bullish tilt in positioning. Considerably more room below than above before hitting a strong reaction zone. That combination completely changes the type of setup that makes sense to look for at that moment. Reading just one of the three cards on its own doesn't give you that same clarity.
Half an hour later, the Regime card still shows positive gamma, but the distance to the Flip dropped to four points. That single change, without touching the other two cards, already signals the room to maneuver shrank.
Regime and Bias are two independent reads, even though they're usually checked together. Regime comes from total Net GEX, the read on how price is likely to react to dealer hedging. Bias comes from call/put dominance, the read on which way positioning is leaning. It's perfectly normal for the two not to tell exactly the same story at a given moment.
For example, the market can sit in positive gamma (a stable Regime, range-bound behavior) while Bias shows put dominance (cautious positioning). That combination isn't a contradiction: it's additional information. It says the market is behaving calmly for now, but options positioning is leaning more toward protection than directional bets. Seeing both cards together, instead of just one, is what reveals that nuance.
The three cards don't necessarily shift at the same pace. Regime, built on total Net GEX, tends to move in a more gradual way across the session, since it's summing pressure from the entire options chain at once. Bias can swing faster, since a handful of large orders on one side can shift call/put dominance within minutes. Space updates constantly, simply because it tracks spot price directly, and price itself is the fastest-moving input of the three.
Knowing that rhythm ahead of time changes how you read a shift on any one card. A quick move in Bias, on its own, isn't unusual and doesn't necessarily mean anything is changing structurally. A shift in Regime, on the other hand, tends to be a more meaningful event precisely because it moves less often. Space sitting near zero on one side simply means price is close to that level right now, regardless of how Regime or Bias look at that same moment.
Most of the time, one side of Space carries considerably more distance than the other, since the Call Wall and Put Wall don't usually sit symmetrically around spot. Occasionally, though, both numbers shrink at the same time. Say Space shows eight points to the Call Wall above and eleven points to the Put Wall below, on an instrument that normally carries forty or fifty points of room on each side.
That squeeze reading tells you price is boxed between two structural levels at once, not just approaching one of them. Regime and Bias still matter here, but Space becomes the card doing most of the talking, since the setup that makes sense in a wide-room session, riding a move toward a distant level, usually doesn't apply when both walls sit close together. A break of either wall in that kind of squeeze tends to carry more weight than the same break would in a session with wide room on both sides, simply because there's so little structural distance left to absorb the move.
Watching how quickly that squeeze resolves, rather than which direction it breaks first, is often the more useful read. A squeeze that holds for an extended stretch without resolving in either direction says something different than one that breaks within minutes of forming.
This card shows your current spot price along with the distance to the nearest key levels above and below, like the Call Wall and Put Wall, with the point difference to each one. It answers "if price keeps going this way, how far is the next reaction zone?"
| Card | What it shows | Question it answers |
|---|---|---|
| Regime | Net GEX, distance to the Flip, positive/negative gamma | What regime am I standing in? |
| Bias | Call/put pressure dominance | Which way is positioning leaning? |
| Space | Spot and distance to the nearest levels | How far is my next level? |
Every field, including the thresholds that define when a reading marks as strong or moderate, is documented in the GammaContext Gex Panel reference guide.
None of the three cards is a standalone entry signal. Together, they build the full context before you decide.
Figure 2. The panel connected live, with its cards and the Max Change heatmap, inside NinjaTrader 8.
Do all three cards update live? Yes. The panel reads the same live feed as the rest of the suite. Every card updates without you refreshing anything.
Does the Bias card predict price direction? No. It shows the current dominance of options positioning, not a prediction. It's context, meant to be combined with the rest of your analysis.
What's the difference between Space and just looking at the levels on the chart with GCIGexLevels? GCIGexLevels draws the levels over price. The Space card summarizes the exact distance in one place, without you eyeballing the calculation.
Does the panel have more cards besides these three? It also includes a Max Change heatmap, covered in the next guide. A Verdict section is marked as coming soon and isn't active yet.
Does it need extra setup to show the three cards? No. All three appear automatically once you connect your Key. There's no separate activation for each one.
Can I move the panel window to a second monitor? Yes. It's an independent floating window inside NinjaTrader, so you can drag it to any connected monitor.
Which card wins if Regime and Bias don't agree? Neither wins on its own. They're two distinct reads on the same market moment, and combining them is exactly what gives you the full context before you decide.
Which card is worth watching most closely during a fast session? Space, since it tracks spot directly and moves the fastest. Regime and Bias give you the backdrop; Space tells you how close that backdrop actually is to mattering right now.
You now know how the three cards roll up your market context into one place. The next step is the panel's fourth piece: the heatmap that tells you whether gamma is actually moving over the last few minutes.
