RadarPulse: a FlowAlgo alternative with a 0-100 flow score

What traders want from a flow scanner

Strip away the branding and most flow-scanner users are after the same handful of things: a way to cut the firehose of daily options prints down to the few that matter, a sense of which prints are significant and why (volume vs. open interest, premium spent, days to expiry, sweep vs. block), context on whether informed money is involved, and a price that fits how seriously you trade. A good alternative should cover all four. If you're mapping the concept itself, our primer on unusual options flow explains the underlying signal.

How RadarPulse delivers it

• 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, buying or selling, and at what aggression.
• Congress, Trump and 13F trackers. See congressional stock trades, the Trump trades tracker, and 13F institutional holdings alongside the flow.
• Radar (AI chat) + Vera (AI equity research). Built-in AI explains any print in plain English and runs fundamental research on any name.
• Free $100K paper trading + Academy. Practise acting on flow signals at zero cost, no card required, with an anonymous leaderboard.

FloAlgo's approach: what it does well

FloAlgo has built a durable reputation in the retail trading community by doing one thing with real consistency: delivering fast, filtered alerts on unusual options activity. The service is built around real-time sweep and block detection, with alert delivery designed around speed, the goal is to surface a notable print the moment it hits the tape so that the trader has the maximum window to act. Understanding FloAlgo's genuine strengths is important context before comparing it to RadarPulse, because an honest comparison requires acknowledging what each tool is actually good at rather than positioning one as uniformly superior to the other.

A few specific things FloAlgo does well that are worth acknowledging candidly:

• Fast alert delivery. FloAlgo's infrastructure is oriented toward latency. Traders who are active during market hours and want to be notified the instant a large sweep prints have found it a reliable tool for that purpose.
• Sweep detection and premium size filters. FloAlgo filters by premium size (minimum dollar value of the options contract) and flags sweeps, multi-leg executions that indicate aggressive directional intent. Both of these are foundational capabilities for options flow scanning.
• Discord integration and community layer. FloAlgo routes alerts into Discord, which has become a preferred delivery channel for active traders who want to discuss prints in real time. The community commentary around a live alert can add interpretation that a raw data feed does not provide on its own.
• Familiar, focused interface. FloAlgo's web interface is intentionally narrower in scope than RadarPulse's multi-tool dashboard. For traders who want a single focused flow table without the broader context layers, that simplicity can be a genuine advantage.
• Established track record. FloAlgo has been operating long enough that there is a meaningful body of trader feedback, YouTube content, and community lore around how to use it. That ecosystem has value beyond the raw product.

One thing worth understanding about the name: the "algo" in FloAlgo refers to the alert algorithms that filter and surface unusual prints, not a trading algorithm in the systematic or quantitative sense. FloAlgo surfaces what the algos detected; the trade decision is entirely the user's. This is an important clarification because some newer traders assume the product involves automated trading.

FloAlgo's alert-only model also has a structural characteristic that is worth naming before diving into the comparison: the alert tells you that something happened and roughly what. It does not tell you how unusual that print is relative to everything else that printed today, or how it ranks against the day's other notable activity. That context gap is precisely where RadarPulse's scoring model was designed to fill in. On a busy session, a trader may receive dozens of FloAlgo alerts across the day. Without a scoring layer, deciding which of those alerts deserves the most attention requires either a deep familiarity with typical volumes in each name, or a manual scan of the raw data that the alert pointed at. RadarPulse's scoring model makes that ranking automatic and explicit, and it does so across every print in the universe rather than only those the trader happens to be watching.

Where the approaches diverge: scoring vs alerting

The clearest way to describe the philosophical split between FloAlgo and RadarPulse is this: FloAlgo is primarily an alerting product, and RadarPulse is primarily a scoring product. Both surface unusual options activity, but they do it with different first principles, and those first principles shape the entire user experience downstream.

In an alerting model, the system detects prints that cross predefined thresholds (premium above a floor, sweep execution type, etc.) and routes those events to the trader. The trader then does the interpretation work: is this notable? How notable? Is it more interesting than the five other alerts that came in the last ten minutes? The trader's judgment fills the gap that the system does not close.

In a scoring model, the system assigns every qualifying print a numeric unusualness score before surfacing it. That score reflects how the print compares to everything else that day, not just whether it crossed a threshold, but how far above that threshold it sits relative to the full distribution of today's activity. The day's highest scorers are then ranked and presented as a curated list. The trader's judgment is still essential, but it starts from a more grounded baseline.

RadarPulse's composite score is computed from six weighted factors:

• Volume / Open Interest ratio (40% weight). The core signal of unusual activity, a high volume relative to existing open interest indicates fresh directional interest, not a roll or a close. This is the largest single factor because it most directly reflects unusual positioning.
• Dollar premium (30% weight). Raw premium spent, normalized for context. A $500,000 sweep in a name that routinely sees that size is less unusual than a $200,000 sweep in a name that rarely sees large prints. The weighting reflects how much information premium carries after Vol/OI is already accounted for.
• Execution type (10% weight). Whether the order hit the ask (aggressor-buy) versus bid (aggressor-sell), and whether it was a sweep, a block, or a split fill. Aggressive sweeps carry more directional signal than passive fills.
• Aggressor side (10% weight). The directional bias inferred from the execution: bullish, bearish, or neutral. This factor combines with execution type to distinguish a bullish sweep from a hedging block.
• Days to expiry (5% weight). Short-dated options are more directional by nature; far-dated options can reflect longer-term positioning or hedging. DTE contextualizes what kind of bet the print represents.
• Time of day (5% weight). Opening and closing prints carry different informational content than mid-session prints. A large sweep in the first ten minutes of trading has different context from the same sweep at 2:45 p.m.

All six factors are disclosed and visible per individual print in RadarPulse, not aggregated into an opaque number. This transparency is intentional: it means a trader can see not just what the score is, but why it is that high, and decide whether the specific combination of factors is relevant to their thesis.

The practical implication for comparing the two tools: an alert tells you that a threshold was crossed. A score tells you where that print ranks against every other threshold crossing today. For a trader managing a watchlist across a session, the ranking is often the more useful piece of information, it tells you where to direct attention when you cannot look at everything.

RadarPulse's Top 25 leaderboard is the direct output of this scoring model. It updates continuously during market hours, and prints are tagged EXTREME (top of the distribution), ELEVATED (significantly unusual), or NOTABLE (worth tracking but less urgent). A trader who checks the leaderboard once an hour has a reasonably complete picture of the day's notable unusual activity without having to triage a queue of raw alerts.

Data access and platform integration

FloAlgo's primary integration path is Discord. Alerts are routed into Discord channels, which allows for community commentary and group discussion around individual prints. For traders who are already embedded in Discord-based communities, this integration fits naturally into an existing workflow. The web interface serves as a supplementary view for traders who want to browse the flow outside of Discord.

RadarPulse is structured differently: it is a self-contained platform with its own live options flow feed, no Discord routing required, and a broader set of built-in data layers that sit alongside the flow. The platform includes:

• Live streaming flow (15-minute delayed on Pro and above, real-time on Elite). RadarPulse generates its own options flow from the OPRA tape, traders on the platform do not need a separate data subscription to get real options prints. The delayed feed is a genuine continuous scan of the universe of options activity, not a sampled or batch-updated dataset.
• Congress stock trade tracker. STOCK Act disclosure filings, updated as they come in, with filing latency flagged when reports are submitted late. Every House and Senate member's reported stock trades, searchable by member, ticker, and transaction type.
• Trump trade tracker. A live policy basket covering the sectors most directly affected by Trump administration policy, Energy, Defense, Steel, Crypto, Financials, and Trump Media, with policy headlines mapped to the relevant sectors.
• 13F institutional holdings tracker. Quarterly institutional filings from major funds, giving visibility into large-fund positioning in individual names.
• Earnings calendar. Upcoming earnings dates integrated into the flow context, so that an unusual options print ahead of an earnings event can be understood in that context immediately.
• Radar AI chat assistant. A built-in conversational interface for asking questions about individual prints, ticker context, or broader market conditions, grounded in the flow data visible in the session.
• Vera AI equity research. A separate AI agent for fundamental research on individual names, balance sheet summaries, earnings trend analysis, and analyst consensus data.

One integration capability that is particularly useful for traders who use multiple tools is RadarPulse's CSV import with auto column detection. The import system accepts exports from FloAlgo, Unusual Whales, and most broker platforms, and automatically maps columns to RadarPulse's schema for scoring. This means that a trader who subscribes to FloAlgo can take their FloAlgo export at the end of the session and run it through RadarPulse's scoring engine to add a composite score to the raw alert data they already have. The two tools are not mutually exclusive in this respect, they can be layered.

The reverse is also possible: a trader can use RadarPulse as the primary live flow source and use FloAlgo's Discord community for color and discussion on the same prints. Many active traders who evaluate both tools end up running them in parallel for different purposes rather than treating the choice as binary.

The political flow tracker, the combination of the Congress tracker and the Trump trade tracker, is a RadarPulse exclusive that has no direct equivalent in FloAlgo. This is discussed in more detail in the next section.

Congress trade tracking: the RadarPulse differentiator

The STOCK Act (Stop Trading on Congressional Knowledge Act) requires members of the House and Senate to disclose personal stock trades within 45 days of the transaction. These disclosures are publicly filed, but the raw filing data is fragmented, often submitted in non-machine-readable formats, and varies in completeness and timeliness by member. RadarPulse aggregates and normalizes this disclosure data into a searchable, filterable tracker that covers every House and Senate member's reported trades.

Several features of the tracker are worth understanding for traders who are evaluating it as a signal source:

• Late filing flags. The 45-day reporting window is frequently exceeded by members who file late. RadarPulse flags late disclosures separately from on-time ones, which is relevant context when evaluating how fresh a disclosed trade actually is relative to when it was made. A trade disclosed 80 days after execution has a very different informational character than one disclosed 10 days after.
• Ticker-level cross-reference. Traders can look up a ticker and see which members have recently disclosed trades in that name, making it straightforward to check whether a ticker with unusual options flow also has recent congressional disclosure activity.
• Historical context. The tracker accumulates historical disclosures, allowing users to see a member's trading pattern over time, whether recent trades in a sector are consistent with their history or represent a new position.

The Trump trade tracker operates differently from the Congress tracker. Rather than filing-based disclosure data, it tracks a curated basket of sectors and names that research and market analysis suggest are most directly tied to Trump administration policy changes: Energy (fossil fuel and LNG-related names), Defense (names with federal contract exposure), Steel and metals (tariff-sensitive names), Crypto (policy-sensitive given the administration's stated stance), Financials (deregulation and banking-related names), and Trump Media. Policy headlines, executive orders, regulatory announcements, tariff decisions, are mapped to the relevant basket sectors in the tracker.

For options flow traders, the relevance of both trackers is in what they add to the interpretation of unusual prints. An unusually large call sweep in an energy name is interesting on its own terms. That same sweep, combined with a recent congressional disclosure of purchases in the same name and a policy headline about LNG export permitting, becomes a different kind of signal. The multi-source confluence is what the political trackers are designed to surface.

FloAlgo does not include political disclosure data in any form. The Congress and Trump trackers are a RadarPulse exclusive in the options flow tools category. This cross-domain capability, connecting unusual options activity with congressional and executive policy signals, is one of the clearer points of differentiation between the two platforms, and one that is difficult to replicate by combining FloAlgo with a third-party congressional tracker, because the integration and cross-referencing is built into the RadarPulse interface.

For traders who have developed a thesis around policy-sensitive sectors, or who specifically want to know whether informed political actors are trading alongside or ahead of unusual options flow in the same names, this combination of data layers is not available from any other single options flow tool at RadarPulse's price point.

Pricing comparison: what you get per dollar

FloAlgo's pricing as of 2026 sits in the range of approximately $79 to $149 per month depending on the plan and any promotional pricing that may be in effect; verify current pricing on their site, as it changes periodically. At FloAlgo's entry price point, the core offering is real-time sweep and block alerts with Discord delivery and the associated community layer.

RadarPulse pricing at launch is structured across three paid tiers, with a meaningful free tier that requires no payment information:

• Basic: $12/mo (founding-member pricing). Includes the scored flow scanner, daily Top 25 with EXTREME/ELEVATED/NOTABLE flags, whale detection, Congress tracker, Trump trade tracker, 13F tracker, Radar AI chat, and Vera AI research, all on 15-minute-delayed flow. A 14-day free trial is included.
• Pro: $29/mo. Adds expanded alert capacity, saved filters, push notifications, cross-device sync, and the earnings calendar integration. Still on 15-minute-delayed flow.
• Elite: $59/mo. Adds the real-time options tape for traders who need to react within the same minute a print appears. Elite also includes the full developer API access and the highest-tier alert volume.
• Free forever: Academy + $100K paper trading wallet + public leaderboard. No credit card required. The paper trading wallet lets traders practice acting on flow signals at zero cost and see their ranking on an anonymous public leaderboard.

The per-feature value comparison at the Pro tier is illustrative. At $29/mo, RadarPulse Pro includes live streaming flow (15-minute delayed), the Top 25 leaderboard with scoring, push alerts, the Congress tracker, the Trump trade tracker, the earnings calendar, and both AI tools. That feature set at $29/mo compares to FloAlgo's entry price of approximately $79/mo for its alert-only, Discord-integrated offering without the political trackers or scoring model.

The free tier difference is also meaningful for traders who are evaluating tools before committing. RadarPulse's paper trading wallet is a functional $100,000 simulated account, not just a demo mode, with a leaderboard that shows real standings. Traders can practice building a flow-reading discipline and testing how they would have acted on signals, at no cost and without providing payment information. FloAlgo does not offer a comparable free tier.

A few caveats on the price comparison that are worth stating honestly:

• FloAlgo's real-time alert delivery is genuinely faster than RadarPulse's 15-minute-delayed flow on Basic and Pro. If sub-minute latency on alerts is a hard requirement for your trading style, that speed differential is a real factor that pricing alone does not resolve.
• FloAlgo's Discord community has scale and history that RadarPulse's platform-native community does not yet match. Community value is difficult to price but real.
• Both tools should be evaluated with a trial if at all possible. The right tool is the one that fits how you actually trade, not just the one with the better feature list on paper.

Who should use each tool

The most useful framing for this decision is not "which tool is better" but "which tool fits how I trade." Both FloAlgo and RadarPulse are legitimate options flow tools with real user bases and genuine capabilities. The choice depends on which model maps more cleanly to your workflow, your data needs, and your budget.

FloAlgo is likely the better fit if:

• You are an active day trader who is at the screen during market hours and needs to react to large sweeps within minutes of execution. FloAlgo's alert infrastructure is built for that latency profile.
• You are already embedded in a Discord-based trading community and want alerts routed directly into the tools you already use for communication and discussion.
• You value community commentary on live prints. FloAlgo's Discord community has a track record and scale that provides social context on flow alerts in real time.
• You prefer a simpler, more focused interface. FloAlgo's web product is narrower in scope than RadarPulse's multi-tool dashboard, if you want one clean flow table and not much else, that focus may be preferable.
• You do not need political disclosure data (Congress, Trump policy baskets) as part of your flow research. If your edge is purely speed and alert volume rather than multi-signal confluence, the political data layer adds interface complexity without adding value.
• You trade names where real-time execution is the primary variable. Scalpers and very short-term options traders who need sub-minute latency will find FloAlgo's real-time feed more aligned with their execution requirements than RadarPulse's delayed feed on Basic and Pro.

RadarPulse is likely the better fit if:

• You want every print scored and ranked rather than receiving a stream of raw alerts that require manual triage. The Top 25 leaderboard and composite 0-100 score give you a structured view of the day's unusual activity without having to process every alert individually.
• You want Congress and Trump policy data integrated with your flow feed. If your trading thesis involves policy-sensitive sectors, cross-referencing unusual options prints with congressional disclosure data is a workflow that RadarPulse supports natively and FloAlgo does not.
• You use multiple data sources and want to consolidate. RadarPulse's CSV import accepts FloAlgo exports, Unusual Whales exports, and broker data, so it can serve as a scoring and analysis layer on top of data from other sources.
• You want an AI assistant alongside your flow data. Radar's built-in chat is grounded in the flow you are seeing in the same session; Vera provides fundamental research on any name without leaving the platform. Neither tool has an equivalent in FloAlgo.
• You want a lower price point with broader feature coverage. At $12/mo for Basic or $29/mo for Pro, RadarPulse covers more capability categories than FloAlgo's entry offering at its current price.
• You are newer to options flow reading and want a structured learning environment. RadarPulse's Academy and free paper trading wallet are designed to help traders build flow-reading discipline before committing real capital. The EXTREME/ELEVATED/NOTABLE tagging system also provides a more structured framework for learning what "unusual" actually means in quantitative terms.
• You trade mid-session or end-of-day rather than intraday. If your workflow involves reviewing the day's flow at a set time rather than reacting to real-time alerts, the 15-minute delay on Basic and Pro is not a meaningful limitation, and RadarPulse's scoring and ranking model adds substantially more value than an alert-only system.

Using both tools together. A meaningful number of active traders who evaluate both conclude that the most effective setup is to use them for different purposes rather than as direct substitutes. A common pattern: FloAlgo for real-time community alerts during market hours (fast notification, social context), and RadarPulse for end-of-session review and analysis (scoring, ranking, political cross-reference, AI research). The CSV import capability makes this workflow explicit, FloAlgo's session export can be scored in RadarPulse after the close. If budget allows for both, this layered approach gets more out of each tool than using either in isolation.

If you are ready to evaluate RadarPulse, the waitlist is the first step. Founding-member pricing is available to early subscribers: join the waitlist.

One practical note on evaluating either tool: options flow signals are probabilistic, not deterministic. No scanner, whether alert-based or scoring-based, predicts market direction with certainty. Unusual prints can reflect informed positioning, but they can equally reflect hedging activity, structured product creation, or institutional risk management that has no directional implication at all. The scoring model in RadarPulse helps separate the highest-probability-of-information prints from the noise, but it does not eliminate uncertainty. Both tools are research aids that inform judgment; neither replaces it. Evaluate whichever tool you choose with that framing in mind, and use a trial or the free paper trading environment to build a track record before sizing real positions around flow signals. The discipline of tracking your own hit rate on flow-based decisions, which RadarPulse's paper trading wallet facilitates, is one of the most useful practices available to flow traders regardless of which alerting or scoring tool they use.

Frequently asked questions

What is a good alternative to FlowAlgo?

FlowAlgo is a real-time options-flow scanning service. RadarPulse is an alternative with a 0-100 unusualness score on every trade, a daily Top 25 with EXTREME/ELEVATED/NOTABLE flags, whale detection, and Congress, Trump and 13F trackers. It generates its own real flow (15-minute delayed, real-time on Elite) so you don't need a separate feed, and adds AI chat and AI equity research.

How does RadarPulse rank unusual options activity?

RadarPulse computes a 0-100 unusualness score using four disclosed factors: volume relative to open interest, dollar premium, days to expiry, and aggressor side. All four components are visible per print. The highest-scoring prints of the day are collected into a daily Top 25 with EXTREME, ELEVATED, and NOTABLE severity tags.

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's options flow real-time?

RadarPulse generates its own real options flow on a 15-minute delay on every paid tier, workable for studying unusual activity, building watchlists, and following smart-money positioning. Real-time tape is available on the Elite tier for traders who need to react inside the same minute.
