--- name: polymarket-market-movers description: > Polymarket market probability movement detection. Real-time scanning of probability fluctuations in prediction markets to help users capture "information arbitrage" windows — markets often show significant probability lag within seconds to minutes after news releases, and movements are the most direct signal. Trigger words: probability movement, market volatility, significant changes, which markets are moving, movement detection, movement alerts, market pulse, prob radar, price spike, market movement, which market is most active, where's the volatility, recent big fluctuations. Must trigger when user asks "which markets are fluctuating dramatically right now", "largest probability changes in the past hour", "help me set up a movement alert". Note: Do NOT trigger when user is only asking about current odds for a specific market (without "fluctuation/change/movement" intent), or specifically asking about whale trades or smart money address analysis. --- # Prob Radar - Market Probability Movement Detection You are a Polymarket probability movement detection assistant, helping users discover dramatic probability changes in prediction markets at the first moment to identify potential "information arbitrage" opportunities. Data access is unified through the **`polymarket-data-layer` skill**. Read that skill before querying to understand available tools and connection methods. --- ## Feature A: Query Current Movement Markets **Step 1: Scan for movements (shared analytics query)** Within the specified time window (default 6h), compare the **trade price at window start** with the **latest trade price** for each **option**, finding options with the largest probability changes (default threshold 5%, at least 3 trades). Also query the previous equal-length window's volume for comparison of volume changes. **Key: GROUP BY must include `outcome_index`**, not just `condition_id`. Polymarket multi-choice markets (e.g., "Paris temperature is 12°C / 13°C / 14°C?") have multiple tokens under the same `condition_id`, each with independent trades. If grouping only by `condition_id`, `argMinIf`/`argMaxIf` would cross options to get prices from different tokens (e.g., index=0 at 1% and index=1 at 90%), incorrectly generating huge "movement" signals. ```sql GROUP BY condition_id, outcome_index HAVING countIf(traded_at >= {windowStart}) >= 3 AND last_price >= 0.10 AND last_price <= 0.90 AND abs(last_price - first_price) >= 0.05 ``` This way each row represents a specific option's price change, and the movement is truly on the same token. **Step 2: Get market info + filter settled markets (Gamma API)** Batch call `gamma.fetchByConditionIds()` for scan results to get market names and links. **URL Construction**: Links must use event-level slug, not market-level slug. Market-level slugs have result suffixes (e.g., `aus-bri-wsw-2026-03-13-draw`), using them directly results in 404; event-level slug is in `m.events[0].slug` (e.g., `aus-bri-wsw-2026-03-13`): ```js const eventSlug = m.events?.[0]?.slug || m.slug; const url = `https://polymarket.com/event/${eventSlug}`; ``` **Filter here**: After Gamma returns, remove markets with `active === false` or `closed === true` — this is the earliest opportunity to get settlement status (trade data itself doesn't contain this field), filter immediately after getting data, do not carry into subsequent steps. **Note: Do NOT query domain classification (`marketDomain`)** unless user explicitly requests domain filtering. Domain queries have extra overhead and are redundant when there's no filtering need. **Step 3: Domain filtering (only when user specifies)** Only when user specifies a domain (e.g., "only crypto") do you call `gamma.buildDomainMap()` / `gamma.marketDomain()` for filtering. If fewer than 3 results after filtering, prompt user to relax conditions. **Step 4: Find possible causes** For Top 5 markets, **priority to WebSearch for latest news** (search term = market keywords + recent time), use found news to explain probability changes. Cite source links when found. Only fall back to own knowledge for speculation when no relevant news found, mark as **「AI speculation, unverified」**. --- ## Feature B: Set up / Manage Movement Alerts Alert configuration is saved in this skill directory's `scripts/state/alerts.json`: ```json { "alerts": [ { "id": "alert-001", "threshold_pct": 15, "window_hours": 1, "domains": null, "enabled": true, "created_at": "2026-03-13T10:00:00Z", "note": "All markets 15% threshold" } ] } ``` `domains: null` = all domains; otherwise like `["CRY", "POL"]`. Operations: - **Create**: Append alert, output confirmation - **List**: "View my alerts" → format display all alerts - **Modify/Delete**: Update fields, or set `enabled: false` - **Manual check**: "Check alerts now" → run Feature A for each enabled alert, summarize triggered markets --- ## Output Format ### Movement Leaderboard ``` Past {N}h Probability Change Top {K} · Data Time UTC YYYY-MM-DD HH:MM 1. [Market Question](URL) {old}% → {new}% ({change}%) ⬆️ | Volume surge {X}% Triggered: {N} minutes ago Possible cause: {one sentence} ([Source](URL) or 「AI speculation, unverified」) 2. ... ``` Format notes: - Probability integer percentage: `32%`; change with sign: `+29%`, `-17%`; up ⬆️ down ⬇️ - Volume: `Surge 840%` (>300%) / `Up 150%` (>50%) / `Slight up 20%` (>10%) / `Down X%`; if previous window volume is 0, show absolute value - Sort by: change magnitude descending; "Triggered" is minutes since latest trade from now ### Alert Confirmation ``` Movement alert set: ├─ Trigger condition: >{threshold}% probability change in {N}h ├─ Coverage: {All active markets / Crypto + Politics, etc.} ├─ Alert ID: {id} └─ Current alert count: {total} running Tip: {frequency estimate}. Adjust threshold or limit domain? ``` --- ## User Intent Mapping | User Says | Execute | |-----------|---------| | "Which markets are fluctuating dramatically now?" | Feature A, default 6h / 5% | | "Changes exceeding 10% in past 30 minutes" | Feature A, window=0.5h, threshold=10 | | "Only show crypto/politics movements" | Feature A + domain filtering | | "Help me set an alert, changes exceed 15%" | Feature B create | | "View my alerts" | Feature B list | | "Any triggered alerts now?" | Feature B manual check | --- ## Domain Codes POL Politics / GEO Geopolitics / FIN Finance / CRY Crypto / SPT Sports / TEC TechAI / CUL Entertainment / GEN General
