RadarPulse: a SpotGamma alternative for scored options flow

Two different jobs: dealer positioning vs. unusual flow

It's worth being clear up front, because these tools aren't straight substitutes. SpotGamma's specialty is dealer gamma exposure and positioning, modelling how options dealers are hedged and where structural support/resistance levels sit. That's a market-structure lens, popular with traders who build a thesis around how dealer hedging flows move the underlying.

RadarPulse's specialty is the flow itself: which specific options prints are unusual right now, how unusual (a transparent 0–100 score), and what smart money is doing around those names. If your question is "where are dealers pinned," SpotGamma is purpose-built for that. If your question is "what unusual activity is hitting the tape, and is informed money behind it," that's what RadarPulse is built to answer. Plenty of traders care about both. If you're newer to the flow side, our primer on unusual options flow covers the underlying signal.

What RadarPulse delivers

• A 0–100 unusualness score on every trade. Volume/OI ratio, dollar premium, days-to-expiry, and aggressor side, four disclosed factors, visible per print, so the ranking reflects what flow readers actually weigh, not a black box.
• A daily Top 25 with clear flags. The day's most unusual activity, ranked and tagged EXTREME, ELEVATED or NOTABLE so you scan severity first and drill into the strongest signals.
• Whale detection. Block and sweep orders moving real size are surfaced with the aggressor side flagged.
• Congress, Trump and 13F trackers. See congressional stock trades, the Trump trades tracker, and 13F institutional holdings alongside the flow, smart-money context in one place.
• Radar (AI chat). A built-in AI markets assistant that explains any ticker or print in plain English.
• Vera (AI equity research). An AI equity-research desk for a structured fundamental read on any name surfaced by the flow.
• Free $100K paper trading + Academy. Practise acting on flow signals at zero cost, no card required, with an anonymous leaderboard.

A factual feature comparison

The table describes RadarPulse's capabilities in detail. SpotGamma and RadarPulse focus on different problems, so for the SpotGamma column we only note what's widely and publicly known and otherwise defer to their site, the honest move is to compare each on its own terms.

"See their site" means we're deliberately not stating another company's specifics, verify current SpotGamma features and pricing on their own site.

RadarPulse pricing

• Basic: $12/mo, with a 14-day free trial. Scored scanner, daily Top 25, whale detection, Congress and 13F trackers on 15-minute-delayed flow. Radar AI chat and Vera AI equity research included.
• Pro, $29/mo. More headroom for active users, saved filters, more alerts, cross-device sync.
• Elite, $59/mo. Adds the real-time tape for traders reacting inside the same minute.

Flow is 15-minute delayed on every tier except Elite. Full breakdown at the pricing page.

Which should you pick?

If dealer gamma positioning and structural levels are the core of your process, SpotGamma is purpose-built for that lens, compare it on its own terms. RadarPulse is the better fit if you want accessible, transparently-scored unusual flow, a ranked daily Top 25, Congress and institutional context in the same view, and AI chat plus equity research built in, at a low entry price with a real trial. Many traders pair a flow scanner with a positioning tool; if you mainly need the flow side, start at the Learn hub or our guide to the best free options flow scanner.

SpotGamma: what it does and who it serves

SpotGamma is a dealer positioning and gamma exposure analytics platform. Its core product is modelling how options market makers, dealers, are hedged at any given point in time, and using that model to derive structural information about the underlying market. The platform's key outputs include gamma exposure (GEX) data broken down by strike and expiry, hedging wall identification, dealer positioning estimates, and implied gamma levels that signal where the market is likely to find support or resistance based on dealer activity rather than traditional technical analysis.

One of SpotGamma's distinctive indicators is HIRO, the Hedging Impact from Rolling Options, which attempts to measure in near real-time how dealer hedging activity is affecting intraday price action. The platform also provides broader options market structure analysis, computing support and resistance levels from the mechanics of how dealers are required to buy and sell the underlying to stay delta-neutral as options prices move.

SpotGamma is primarily used by three groups of traders:

• Macro traders who want to understand structural forces shaping index price action beyond traditional supply/demand analysis.
• Index options traders, particularly those trading SPX, SPY, and QQQ, where GEX mechanics are most influential because of the sheer size of open interest relative to the underlying.
• Sophisticated options strategists who build their market thesis around how dealer hedging flows create and dissolve price gravity at specific strikes.

SpotGamma's pricing is approximately $99 to $499 per month depending on the tier and data depth. Their premium pricing reflects a significant investment in the dealer-positioning data infrastructure, modelling methodology, and the specialized index-options analysis their institutional and professional user base demands. For the current pricing, check their site directly, tiers and prices change.

It is worth emphasizing what SpotGamma is not primarily built for: it is not a tool for scanning the options tape and ranking unusual prints by how unusual they are. It is not a congressional trading tracker. It does not have a built-in AI chat assistant or equity research desk. Its focus is narrow, deep, and specific, which is a strength for the workflow it is designed for and a limitation for traders who need different signals.

SpotGamma's audience also skews toward experienced and institutional practitioners. Their educational content, webinars, and community tend to assume a working knowledge of delta-hedging mechanics, options Greek dynamics, and how market makers manage risk. For a newer trader coming from equities or who is just beginning to learn options, the GEX framework has a steeper entry ramp than a scored flow scanner. That is not a criticism, it reflects SpotGamma's target user, but it is relevant when deciding where to start.

Two different data layers: dealer positioning vs. unusual flow

The most important thing to understand before comparing these two platforms is that they are answering fundamentally different questions about the options market. They occupy different analytical layers, and understanding those layers is more useful than a feature-by-feature comparison.

SpotGamma answers: "Where are dealers positioned right now, and how will their mechanical hedging requirements affect price movement today?" This is a structural question. GEX analysis is essentially asking: given the current state of open interest across strikes and expiries, how much will dealers need to buy or sell the underlying as price moves, and where does that create gravity or magnetic levels? The answer does not tell you what informed institutional traders think about a stock or index, it tells you what the mechanics of dealer hedging will likely do to price dynamics.

RadarPulse answers: "What unusual institutional options activity happened today, how unusual is it relative to historical norms, and what does the broader smart-money picture look like around that name?" This is a flow and positioning question. Unusual flow analysis is asking: relative to this name's average options activity, are traders making unusually large, unusually aggressive, or unusually timed bets, and is there evidence that those bets are informed rather than noise?

These are complementary questions, not competing ones. GEX analysis models the mechanical price dynamics that arise from dealer inventory management. Unusual flow analysis identifies potential directional conviction from institutional traders who may have an informational or analytical edge. Neither approach answers the other's question:

• SpotGamma tells you SPX has a large positive GEX wall at 5,400 that will likely act as resistance today. It does not tell you whether institutional traders are buying calls or puts on individual names that might be correlated with a break of that level.
• RadarPulse tells you NVDA just saw a $4.2M sweep of call options 45 days out, scored 94/100 for unusualness. It does not tell you where the GEX level is that might pin or repel NVDA price action today.

Some sophisticated options traders use both for exactly this reason: SpotGamma for understanding the options market structure and where price gravity exists mechanically, RadarPulse for identifying the unusual institutional positioning signals within that structure. The two lenses together give a richer picture than either alone.

A practical way to think about it: GEX analysis is primarily a tool for the day-of and intraday timeframe, it describes the current state of dealer positioning and how that will mechanically influence price action over the next hours to days as positions roll and expire. Unusual flow analysis operates on a slightly different timeframe, a large call sweep 30-60 days out is a bet that something will happen over the next month, not necessarily today. The two signals can inform each other without competing: the GEX layer tells you about today's mechanical forces, the flow layer tells you where informed money is positioning for the weeks ahead.

Why unusual flow and GEX are complementary signals

The practical case for combining GEX analysis with unusual flow analysis comes down to what each signal captures and what it misses.

GEX from SpotGamma tells you where price is likely to gravitate or repel based on dealer hedging requirements. When dealers are short gamma at a strike, a move toward that strike accelerates because dealers must buy (for calls) or sell (for puts) to hedge, amplifying the move. When dealers are long gamma, a move toward that strike decelerates because their hedging activity works against the move, creating a natural magnetic level. This mechanical dynamic is real and measurable, and it operates regardless of what any individual institutional trader thinks about the market.

Unusual flow from RadarPulse tells you where institutional traders are positioning directionally with meaningful size and conviction. A 92-scored call sweep tells you that someone spent real money making an aggressive, large, short-dated bullish bet, the kind of bet that does not typically come from a retail trader gambling on a meme. Whether that conviction is right or wrong, it represents real informed positioning that can precede major moves.

The most powerful signal is when both agree. Consider these scenarios:

• Confirmation: flow at a GEX support level. A large institutional call sweep appears at a strike that SpotGamma identifies as a high-positive-GEX support level. The mechanical dealer hedging will reinforce a bounce at that level, and a large institutional buyer is betting it holds. Both the structural and the directional signal align.
• Confirmation: put accumulation at a weak-GEX zone. Put flow scores high at a strike where SpotGamma shows dealers are long gamma, meaning dealers are positioned to absorb selling and slow a downward move. But large institutional put buying at that same strike suggests informed traders believe the mechanical support will be overwhelmed. The flow signal is telling you the structure may give way.
• Divergence worth noting. Strong call flow in a name where GEX shows an overhead resistance wall. The institutional buying may be anticipating a gamma squeeze, a break through the wall that forces accelerating dealer buying, or it may simply be targeting a longer time horizon where today's GEX structure is irrelevant.

Neither tool alone captures both dimensions. GEX analysis with no flow context tells you the mechanical structure but not where informed money is positioned within it. Unusual flow analysis with no GEX context tells you where the bets are but not what the mechanical price dynamics look like around those levels. Traders who work with both have a more complete picture of the options landscape than those who rely on a single signal type.

For traders just starting to build their options analytical toolkit, the flow layer tends to be more accessible as an entry point, the signal is more intuitive (large, unusual bet in a specific direction on a specific ticker) than the GEX mechanics, which require understanding dealer hedging dynamics to interpret correctly. RadarPulse's 0-100 scoring is designed precisely to make the flow layer interpretable without deep options theory knowledge. The GEX layer rewards more quantitative options knowledge but also provides a genuinely different and valuable signal for those who can use it.

Broader market intelligence: what RadarPulse adds beyond flow

SpotGamma is intentionally specialized, it does one thing deeply, which is dealer and gamma analytics for the options market structure layer. RadarPulse is built as a broader institutional intelligence platform, and the options flow scanner is the core of it but not the whole of it.

The full RadarPulse platform includes:

• Unusual options flow, scored 0-100. Every print on the tape receives a transparency score from four disclosed factors: volume-to-open-interest ratio, dollar premium size, days to expiry, and aggressor side. The daily Top 25 ranks the most unusual activity with EXTREME, ELEVATED, and NOTABLE severity flags, so you scan the ranking first and drill into the strongest signals rather than reading a raw unfiltered tape.
• Congressional trading disclosures. All House and Senate members are required to file STOCK Act disclosures when they trade individual securities. RadarPulse surfaces these filings in near real-time, showing which members are buying and selling what, with the ability to track individual politicians' trading histories. Congressional trading has historically shown patterns worth monitoring, members sit on committees with oversight of entire industries and sometimes trade ahead of policy decisions.
• The Trump trade tracker. A dedicated tracker for the policy-correlated basket of trades tied to OGE disclosures and known Trump policy positions, tariffs, energy, defense, financial deregulation, and specific names that have historically moved on administration signals.
• Radar, the AI market assistant. A built-in conversational AI that has access to live market data and can explain any ticker, options print, or market concept in plain English. Ask it to summarize what the flow is saying about a name, explain why a specific print scored highly, or give you context on a company before you act on the flow signal.
• Vera, the AI equity research desk. A structured AI research tool for running a fundamental read on any company name surfaced by the flow. When a stock appears in the unusual flow and you want to quickly understand its business, recent catalysts, earnings situation, and analyst sentiment before deciding whether the flow signal is worth acting on, Vera provides that structured context.
• Dark pool and options confluence signals. Identifying cases where dark pool activity and unusual options activity align on the same name, two different types of institutional activity pointing in the same direction, which is a historically stronger signal than either alone.
• Earnings calendar and live market news. So you can see at a glance whether unusual options activity around a name might be earnings-driven and consume relevant headlines without leaving the platform.

For traders who want political catalyst data alongside options activity, the multi-signal layer in RadarPulse goes well beyond what either pure-gamma or pure-flow tools offer individually. The intersection of congressional trading, policy-correlated flow, and unusual institutional options activity in the same platform is a differentiator, SpotGamma does not track Congress or political flow, and most options flow scanners do not either. RadarPulse is designed specifically for traders who believe these signals are related and want to see them together.

The Congress tracker is worth examining in more detail because it represents a genuinely different category of market intelligence. STOCK Act disclosure filings create a public record of when legislators trade individual securities. The latency between the trade and the filing can be days to weeks, but once filed, the disclosure is public and actionable. Some of these trades are routine, index funds, widely-held stocks, portfolio rebalancing. Others are concentrated bets in specific names that the legislator's committee has direct oversight over, or that stand to be directly affected by upcoming legislation. The ability to filter by committee membership, trade size, and timing relative to legislative events makes this a signal stream that no pure-gamma tool captures.

The free $100K paper trading wallet and Academy are also part of the broader platform vision: making it possible to practice reading and acting on flow signals at zero cost, with a real leaderboard, before committing real capital. No card required, no trial expiration on the paper wallet. This is not a feature SpotGamma offers because their platform is not aimed at that stage of a trader's journey, they are focused on practitioners who already have a GEX-based workflow and want better data for it.

Pricing comparison: specialized depth vs. broad coverage

Pricing for both platforms reflects their positioning and target audience. Understanding what each price point buys you is important for deciding where to start or whether to use one, the other, or both.

SpotGamma pricing runs approximately $99 to $499 per month depending on the tier and data depth. The higher tiers include access to more granular GEX data, deeper strike-level analysis, and more frequent data updates. Their pricing reflects the significant infrastructure cost of computing real-time or near-real-time dealer positioning estimates across a large options universe, and the specialized nature of the index-options data they provide. Verify current pricing on their site, it changes.

RadarPulse pricing at launch:

• Basic: $12 per month, with a 14-day free trial. Includes the scored scanner, daily Top 25, whale detection, Congress and Trump trackers, 13F institutional holdings, and Radar AI chat, all on 15-minute-delayed flow. This is a broad feature set at a low entry price.
• Pro: $29 per month. More headroom for active users, saved filters, more alert slots, cross-device sync, and expanded access to the flow history and deeper scoring breakdowns.
• Elite: $59 per month. Adds the real-time tape for traders who need to react within the same minute a print hits. At $59/mo Elite is still well below SpotGamma's entry price.
• Free forever: RadarPulse Academy and $100K paper trading wallet. No card required, no trial expiration. The paper wallet and leaderboard are permanently free, regardless of tier.

The pricing comparison reflects what each platform is optimizing for. SpotGamma's premium pricing is justified by the specialized dealer-positioning data infrastructure, the modelling methodology behind GEX, and the depth of index-options analysis that professional traders require. This is genuinely specialized data that is expensive to compute correctly, and their institutional-leaning user base is willing to pay for it.

RadarPulse at $29 to $59 per month provides unusual flow scoring, Congress and political tracking, an AI assistant, dark pool confluence signals, and push alerts at a fraction of SpotGamma's cost. For retail options traders who want institutional flow signals and political data without the GEX infrastructure investment, RadarPulse covers significantly more ground per dollar.

For sophisticated index options traders who need GEX data as a core part of their process, SpotGamma's dealer positioning depth may well justify its premium, but that does not mean a lower-cost flow tool is redundant alongside it. The signals are different enough that using RadarPulse for unusual flow and political tracking alongside SpotGamma for GEX structure is a coherent combined setup that costs less than most professional data subscriptions in any other market segment.

A note on free trials: RadarPulse Basic includes a 14-day free trial with no card required to access the paper wallet and Academy. This gives new users a genuine opportunity to evaluate the scored flow interface, run paper trades against flow signals, and understand what the platform does before committing.

Which tool belongs in your workflow

The decision between these two platforms, or whether to use both, comes down to your trading style, the types of instruments you trade, your analytical framework, and your budget. Here is a direct breakdown of each case.

Use SpotGamma if:

• You primarily trade index options, SPX, SPY, QQQ, or other products where GEX mechanics are most influential because of the scale of open interest relative to the underlying market. GEX analysis is most actionable on these instruments.
• You want to understand intraday price gravity from dealer hedging and build your trading decisions around structural levels derived from dealer positioning rather than traditional technical analysis.
• You trade with a market-structure analytical framework, your entry and exit decisions are grounded in where the mechanical forces of dealer delta-hedging create support, resistance, and acceleration zones.
• You can justify the higher price for institutional-quality dealer positioning data as a core part of a serious trading operation. At $99 to $499 per month, SpotGamma is a professional tool priced for professional use.
• You want HIRO and similar real-time indicators that attempt to show intraday dealer hedging impact as it happens, giving you a live view of the structural forces shaping price action.

Use RadarPulse if:

• You want to identify unusual institutional options positioning with transparent, auditable scoring, a 0-100 score from four disclosed factors on every print, not a black-box ranking, so you can evaluate why something scored highly, not just that it did.
• You follow Congressional and political flow signals as part of your investment process. If you believe that STOCK Act disclosures and policy-correlated trading are worth monitoring, RadarPulse is built specifically to surface those signals alongside the options flow.
• You want an AI assistant for quick market research without switching tools. Radar can explain a ticker, summarize what the flow is saying about a name, or help you quickly understand a sector catalyst, directly within your flow research workflow.
• You prefer lower pricing with broader feature coverage. At $12 to $59 per month with a free trial, RadarPulse gives active retail traders access to a scored scanner, whale detection, political trackers, AI research, and push alerts at an accessible price point.
• You trade individual stock options rather than primarily index options. Unusual flow analysis is applicable across the full equity universe, large-cap, mid-cap, sector ETFs, not just the major indexes where GEX mechanics are most powerful.
• You are building your options analytical toolkit and want a starting point that is interpretable without deep quant options knowledge. The 0-100 score and ranked Top 25 are designed to be readable by active retail traders; GEX analysis has a steeper learning curve.
• You want push alerts on unusual flow and confluence signals delivered to your phone, so you do not have to watch a screen all day to catch the day's most unusual prints as they happen.

Use both if:

• You are a sophisticated index options trader who already has a GEX-based workflow and wants to add institutional flow and political signals as an additional layer. SpotGamma tells you the structure; RadarPulse tells you where the bets are within that structure.
• Your combined subscription budget allows it. At RadarPulse Pro ($29/mo) alongside SpotGamma's entry tier, the combined cost is still below what many professional trading data subscriptions run for a single data type.
• You want the mechanical context (where dealers are hedged and how price will behave mechanically) plus the directional signal (where institutions are positioning with conviction), neither tool alone gives you both.

The ideal starting point for most active retail options traders is to begin with the flow layer, it is more intuitive, immediately actionable, and available at a much lower price point. If your process matures toward index options and market structure analysis, adding a GEX tool at that point makes sense. If you are already at that stage, the two tools are additive rather than competitive. You can get started with RadarPulse's free paper wallet and Academy without a card, then join the waitlist for full scored flow access. Join the waitlist to be notified when your tier opens.

If you are still evaluating how options flow fits into your process, the unusual options flow guide covers the fundamentals of what the signal is, what drives high scores, and how to separate genuine institutional conviction from noise. The Learn hub collects the full library of guides across flow, Congress tracking, paper trading, and market structure, a good reference as you build out your analytical toolkit.

Frequently asked questions

What is a good alternative to SpotGamma?

SpotGamma is an options analytics service focused on dealer gamma positioning and market-structure levels. RadarPulse is an alternative for traders who primarily want accessible, scored options flow: a 0-100 unusualness score on every trade, a daily Top 25 with EXTREME/ELEVATED/NOTABLE flags, whale detection, Congress and 13F trackers, and AI research. They serve different needs, and some traders use both.

Does RadarPulse show dealer gamma exposure (GEX)?

RadarPulse is built around unusual options flow rather than dealer gamma-exposure modelling. Its focus is surfacing and ranking the day's unusual prints with a transparent 0-100 score, plus whale detection and Congress and 13F smart-money context. If your workflow centers specifically on dealer gamma positioning, check SpotGamma's own site; if it centers on finding unusual flow and what informed money is doing, RadarPulse is built for that.

How much does RadarPulse cost?

RadarPulse Basic is $12/mo with a 14-day free trial. Pro is $29/mo, Elite is $59/mo. The $100K paper-trading wallet, leaderboard, and Academy are free forever with no card required. Flow is 15-minute delayed on every tier except Elite, which adds the real-time tape.

Is RadarPulse easier to use than SpotGamma?

RadarPulse is designed to be approachable: every print gets a transparent 0-100 score from four disclosed factors, the day's most unusual activity is collected into a ranked Top 25, and built-in AI explains any name in plain English. It aims to make reading unusual flow accessible to active retail traders, whereas SpotGamma's dealer-positioning analytics lean more quantitative. Pick the one that matches how you trade.
