Polymarket Analyzer Skill

Detect trading edges and opportunities across Polymarket prediction markets using real-time data from the Gamma and CLOB APIs. Zero authentication required -- all analysis is read-only.

Available Scripts

1. Find Arbitrage Edges (scripts/find_edges.py)

Scans all active markets for pricing inefficiencies:

• Underpriced: YES + NO < $1.00 (guaranteed profit if you buy both sides)
• Overpriced: YES + NO > $1.02 (sell opportunity)
• Calculates profit after fees for each opportunity
• Outputs market name, prices, sum, potential profit, and fee impact

python scripts/find_edges.py
python scripts/find_edges.py --min-edge 0.02 --limit 500

2. Analyze Order Book (scripts/analyze_orderbook.py)

Deep analysis of a single market's order book:

• Spread, mid-price, bid/ask depth (top N levels)
• Bid-ask imbalance ratio (signals directional pressure)
• Thin vs thick book classification
• Liquidity concentration analysis

python scripts/analyze_orderbook.py --token-id <TOKEN_ID>
python scripts/analyze_orderbook.py --token-id <TOKEN_ID> --depth 10

3. Momentum Scanner (scripts/momentum_scanner.py)

Detect markets with unusual activity:

• Volume surges: 24h volume significantly exceeds 7-day average
• Price momentum: recent price moves in one direction
• Liquidity changes: markets gaining or losing depth
• Ranked output by signal strength

python scripts/momentum_scanner.py
python scripts/momentum_scanner.py --min-volume 10000 --limit 300

4. Correlation Tracker (scripts/correlation_tracker.py)

Detect hidden correlated exposure in your portfolio:

• Groups positions by topic (crypto, politics, sports, geopolitics, etc.)
• Detects shared qualifiers ("insider trading", "FIFA World Cup", etc.)
• Warns when correlated clusters exceed concentration limits
• Outputs diversification score (0-100)

python scripts/correlation_tracker.py
python scripts/correlation_tracker.py --json
python scripts/correlation_tracker.py --threshold 0.10

Workflow

1. Run find_edges.py to scan for arbitrage across all active markets
2. For interesting markets, run analyze_orderbook.py to check if the edge is executable
3. Run momentum_scanner.py to find markets with directional momentum
4. Combine findings to identify the best opportunities

Fee Awareness

Most Polymarket markets are fee-free. Crypto 5-min/15-min markets have dynamic taker fees: fee = baseRate * min(price, 1 - price) * size. See references/fee-model.md for the full fee calculator and breakeven analysis.

Strategy Reference

See references/viable-strategies.md for the four strategies that still work in 2026 with win rates, expected returns, and risk profiles.

Important Disclaimers

• This skill performs read-only analysis only -- no trades are executed
• Past patterns do not guarantee future results
• Always verify opportunities manually before trading
• Not financial advice

Polymarket Live Executor

Execute real trades on Polymarket with mandatory human-in-the-loop confirmation. This skill requires L2 authentication (wallet private key) and enforces strict safety controls on every operation.

SAFETY REQUIREMENTS

Every trade requires explicit user confirmation. The agent must:

1. Display full trade details (market, side, size, price, estimated cost)
2. Show current order book context (spread, depth at target price)
3. Wait for the user to type "yes" or "confirm" before proceeding
4. Never batch or auto-confirm trades

Environment safeguards (enforced by all scripts):

• POLYMARKET_PRIVATE_KEY must be set (burner wallet only -- NEVER a main wallet)
• POLYMARKET_CONFIRM=true must be set to enable any trade execution
• Position size hard-capped (default $10, configurable via POLYMARKET_MAX_SIZE)
• Daily loss limit tracked in ~/.polymarket-live/trades.log

Setup

Use the setup wizard to configure everything:

# Step 1: Create a burner wallet
python scripts/setup_wallet.py --create

# Step 2: Fund wallet with USDC on Polygon (manually via MetaMask/bridge)

# Step 3: Copy and fill in .env
cp .env.example .env && chmod 600 .env
# Edit .env with your private key and limits

# Step 4: Verify everything is configured
python scripts/setup_wallet.py --verify

# Step 5: Check on-chain balance
python scripts/setup_wallet.py --check-balance

Or set environment variables manually:

export POLYMARKET_PRIVATE_KEY="0x..."    # Burner wallet only!
export POLYMARKET_CONFIRM=true           # Safety gate
export POLYMARKET_MAX_SIZE=10            # Max $ per trade (default: 10)
export POLYMARKET_DAILY_LOSS_LIMIT=50    # Max daily loss (default: 50)

Review the references/live-trading-checklist.md before any live trade.

Available Scripts

1. Execute Trade (scripts/execute_live.py)

Place a real order on Polymarket.

# Limit order: buy 5 YES shares at $0.60
python scripts/execute_live.py --token-id <ID> --side BUY --size 5 --price 0.60

# Market order: buy $5 worth at market price
python scripts/execute_live.py --token-id <ID> --side BUY --amount 5 --market

# Sell: sell 10 shares at $0.75
python scripts/execute_live.py --token-id <ID> --side SELL --size 10 --price 0.75

The script will display full trade details and require interactive confirmation.

2. Check Positions (scripts/check_positions.py)

View wallet balance, open orders, and trade history.

python scripts/check_positions.py                # Summary
python scripts/check_positions.py --orders        # Open orders
python scripts/check_positions.py --trades        # Recent trades
python scripts/check_positions.py --balance       # USDC balance

Workflow

1. Run analysis with polymarket-analyzer scripts to find opportunities
2. Paper-trade the idea with polymarket-paper-trader first
3. Review references/live-trading-checklist.md
4. Set up environment variables and burner wallet
5. Use check_positions.py to verify wallet state
6. Execute trade with execute_live.py -- confirm when prompted
7. Monitor position with check_positions.py

Risk Controls

• All trades logged to ~/.polymarket-live/trades.log
• Daily P&L tracked and enforced against loss limit
• Position size caps prevent oversized trades
• No autonomous execution -- every trade needs human approval

Important Disclaimers

• This skill executes REAL trades with REAL money
• Use only with burner wallets funded with money you can afford to lose
• Past analysis does not guarantee future results
• Not financial advice -- you are solely responsible for your trades

Polymarket Monitor

Monitor live Polymarket prediction markets for price changes, volume spikes, and spread movements. Outputs structured JSON alerts when thresholds are crossed. All endpoints are read-only and require no API keys.

Prerequisite: This skill uses token IDs from the polymarket-scanner skill. Run scan_markets.py first to discover markets and obtain token IDs.

Quick Start

All scripts require the Python venv at /home/verticalclaw/.venv.

Monitor Multiple Markets for Price Alerts

source /home/verticalclaw/.venv/bin/activate && python polymarket-monitor/scripts/monitor_prices.py \
  --token-id "<TOKEN_ID_1>" \
  --token-id "<TOKEN_ID_2>" \
  --interval 30 \
  --threshold 5.0

This polls every 30 seconds and prints a JSON alert whenever a token's midpoint moves more than 5% from its baseline.

Watch a Single Market Live

source /home/verticalclaw/.venv/bin/activate && python polymarket-monitor/scripts/watch_market.py \
  --token-id "<TOKEN_ID>" \
  --interval 15

Prints a JSON snapshot every 15 seconds with price, spread, and order book depth.

Scripts

monitor_prices.py

Polls multiple tokens at a set interval and emits JSON alerts when price changes exceed a threshold.

Arguments:

• --token-id ID — CLOB token ID to monitor (repeatable, at least one required)
• --interval N — Polling interval in seconds (default: 30, minimum: 5)
• --threshold N — Percentage change to trigger an alert (default: 5.0)
• --max-polls N — Stop after N polls (default: unlimited, use for non-interactive runs)
• --baseline-window N — Number of recent prices to average for baseline (default: 1, meaning compare to last poll)

Output: One JSON object per line for each alert:

{
  "type": "price_alert",
  "token_id": "...",
  "timestamp": "2026-02-26T12:00:00Z",
  "current_price": 0.65,
  "baseline_price": 0.60,
  "change_pct": 8.33,
  "direction": "up",
  "spread": 0.02,
  "poll_number": 5
}

Non-alert polls print a status line to stderr so the agent knows monitoring is active.

watch_market.py

Continuously monitors a single market, printing a JSON snapshot each interval with price, spread, volume, and order book summary.

Arguments:

• --token-id ID — CLOB token ID to watch (required)
• --interval N — Snapshot interval in seconds (default: 15, minimum: 5)
• --max-polls N — Stop after N snapshots (default: unlimited)

Output: One JSON object per line per snapshot:

{
  "type": "market_snapshot",
  "token_id": "...",
  "timestamp": "2026-02-26T12:00:00Z",
  "midpoint": 0.55,
  "best_bid": 0.54,
  "best_ask": 0.56,
  "spread": 0.02,
  "bid_depth": 15000.0,
  "ask_depth": 12000.0,
  "last_trade_price": 0.55,
  "last_trade_side": "BUY",
  "poll_number": 1
}

Data Flow

1. Run polymarket-scanner/scripts/scan_markets.py to find markets and get token IDs
2. Pass token IDs to monitor_prices.py for multi-market alerting
3. Or pass a single token ID to watch_market.py for detailed single-market tracking

Polymarket Paper Trading Engine

Simulate trades against live Polymarket prices with zero financial risk. No wallet, no keys, no money at stake. Portfolio persists across sessions in SQLite.

Quick Start

Initialize a Portfolio

python ~/.agents/skills/polymarket-paper-trader/scripts/paper_engine.py --action init --balance 1000

Buy Shares (Market Order)

# Buy $50 of YES shares using live order book prices
python ~/.agents/skills/polymarket-paper-trader/scripts/paper_engine.py \
  --action buy --token TOKEN_ID --side YES --size 50 \
  --reason "High confidence based on news analysis"

Buy Shares (Limit Order)

python ~/.agents/skills/polymarket-paper-trader/scripts/paper_engine.py \
  --action buy --token TOKEN_ID --side YES --size 50 --price 0.45 \
  --reason "Value buy below fair price estimate"

Check Portfolio

python ~/.agents/skills/polymarket-paper-trader/scripts/paper_engine.py --action portfolio
python ~/.agents/skills/polymarket-paper-trader/scripts/paper_engine.py --action portfolio --json

Close a Position

python ~/.agents/skills/polymarket-paper-trader/scripts/paper_engine.py \
  --action close --token TOKEN_ID --reason "Taking profit"

View Trade History

python ~/.agents/skills/polymarket-paper-trader/scripts/paper_engine.py --action trades

Performance Report

python ~/.agents/skills/polymarket-paper-trader/scripts/portfolio_report.py
python ~/.agents/skills/polymarket-paper-trader/scripts/portfolio_report.py --json

Portfolio Health Check (Session Start)

python ~/.agents/skills/polymarket-paper-trader/scripts/health_check.py
python ~/.agents/skills/polymarket-paper-trader/scripts/health_check.py --json

Runs the full session-start workflow in one command: loads portfolio, fetches live prices, updates DB, calculates drawdown, checks stop losses, evaluates all risk limits. Returns GREEN/YELLOW/RED status.

Finding Token IDs

Token IDs come from the Polymarket Gamma API. To find them for a market:

# Search for markets
curl -s 'https://gamma-api.polymarket.com/markets?limit=5&active=true&closed=false&order=volume24hr&ascending=false' | python3 -c "
import sys, json
for m in json.load(sys.stdin):
    tokens = json.loads(m['clobTokenIds'])
    prices = json.loads(m['outcomePrices'])
    print(f\"{m['question'][:60]}\")
    print(f\"  YES token: {tokens[0]}  price: {prices[0]}\")
    print(f\"  NO  token: {tokens[1]}  price: {prices[1]}\")
    print()
"

Or use the polymarket-scanner skill to discover markets first.

Execute Strategy Recommendations

The executor takes structured recommendations from strategy advisors:

python ~/.agents/skills/polymarket-paper-trader/scripts/execute_paper.py \
  --recommendation '{
    "token_id": "TOKEN_ID",
    "side": "YES",
    "action": "BUY",
    "size_usd": 50,
    "confidence": 0.75,
    "reasoning": "Momentum signal detected",
    "strategy": "momentum"
  }'

Dry run (validates without executing):

python ~/.agents/skills/polymarket-paper-trader/scripts/execute_paper.py \
  --recommendation '{"token_id":"TOKEN","side":"YES","size_usd":50}' --dry-run

Risk Rules (Built In)

Override with --force flag or by passing custom risk_config on init.

How It Works

1. Real prices: Fetches live order book from clob.polymarket.com
2. Book walking: Market orders simulate fills by walking the order book (not mid-price)
3. Fee modeling: Default 0% (most markets), configurable for crypto markets
4. SQLite persistence: Portfolio at ~/.polymarket-paper/portfolio.db
5. Risk engine: Every trade validated against configurable risk rules

API Reference

All scripts support --json for machine-readable output. Key Python functions:

• paper_engine.init_portfolio(balance, name) — Create portfolio
• paper_engine.place_order(token_id, side, size, price) — Execute trade
• paper_engine.close_position(token_id) — Close position

Polymarket Strategy Advisor

You are a prediction market strategist. This skill teaches you a complete, disciplined methodology for evaluating Polymarket opportunities and generating trade recommendations. Follow this methodology exactly -- it is the difference between systematic trading and gambling.

Core Philosophy

1. Edge first: Never trade without a quantifiable edge. "I think YES" is not an edge.
2. Size by confidence: Use Kelly criterion (half-Kelly) to size positions.
3. Cut losers, ride winners: Exit losing trades at the stop. Let winners run to target.
4. Fees eat edge: Most Polymarket markets are fee-free, but always check. A 2% edge with 3% fees is a losing trade.
5. Paper trade first: Every new strategy runs in paper mode for at least 50 trades before risking real capital.

Trading Methodology (Follow These Steps In Order)

Step 1: Scan Markets

Use the polymarket-scanner skill to pull active markets:

source /home/verticalclaw/.venv/bin/activate && python polymarket-scanner/scripts/scan_markets.py --min-volume 10000 --limit 50

Step 2: Filter Candidates

From the scan results, keep only markets that pass ALL of these filters:

Markets that fail any filter are immediately discarded. Do not make exceptions.

Step 3: Detect Edge Type

For each candidate, classify the edge into exactly one category:

Arbitrage -- YES + NO prices sum to less than $1.00 (after fees). This is risk-free profit. Use polymarket-analyzer to verify with orderbook depth.

Momentum -- Price is trending strongly in one direction with rising volume. Run polymarket-analyzer momentum scanner to confirm. Trade in the direction of the trend.

Mean Reversion -- Price spiked sharply on low volume or stale news. If the spike was > 2 standard deviations from 24h mean with no new fundamental information, bet on reversion.

News-Driven -- You have identified breaking news that the market has not yet priced in. This is the highest-edge opportunity for LLM agents. Compare your probability assessment to the current price. Trade only if your edge exceeds 5 percentage points.

If you cannot classify the edge, skip the market. "Interesting" is not a trade.

Step 4: Calculate Position Size (Kelly Criterion)

For each trade, calculate the optimal size:

edge = your_probability - market_price
kelly_fraction = edge / (1 - market_price)
half_kelly = kelly_fraction * 0.5
position_size = portfolio_value * half_kelly

Hard caps on position size:

• Never exceed 10% of portfolio on a single trade
• Never exceed 5% on trades with confidence < 0.7
• Never exceed 2% on news-driven trades (information decays fast)

If Kelly says to bet more than the cap, use the cap. If Kelly says to bet zero or negative, DO NOT TRADE.

Step 5: Validate Against Risk Rules

Before executing, check every rule:

• Daily loss limit not exceeded (5% of portfolio)
• Weekly loss limit not exceeded (10% of portfolio)
• Maximum 5 open positions at once
• No two positions in correlated markets (e.g., "Will X win?" and "Will X lose?" are the same bet)
• Maximum drawdown from peak not exceeded (20%)
• Position size within Kelly cap

If ANY rule fails, do not trade. Log the skip with the reason.

Step 6: Document and Execute

For every trade recommendation, output this exact format:

TRADE RECOMMENDATION
====================
Market:      [market question]
URL:         [polymarket.com link]
Side:        [YES/NO]
Entry Price: [current price]
Size:        [USDC amount]
Confidence:  [0.0-1.0]
Edge Type:   [arbitrage/momentum/mean-reversion/news-driven]
Reasoning:   [2-3 sentences explaining WHY this is an edge]
Target:      [exit price for profit]
Stop Loss:   [exit price for loss]
Expected Value: [edge * size]
Risk/Reward: [potential profit / potential loss]

Never recommend a trade without filling in every field.

When NOT to Trade

Stop trading entirely if ANY of these conditions are true:

• Daily loss > 5% of portfolio: Walk away. The market will be there tomorrow.
• Weekly loss > 10% of portfolio: Stop for the rest of the week.
• Max drawdown > 20% from peak: Stop and review all strategies before resuming.
• Three consecutive losses: Pause and review. Are you following the methodology or improvising?
• No clear edge on any market: Having no position IS a position. Cash is king.
• Market is resolving within 1 hour: Too late. Prices are efficient near resolution.
• You feel compelled to "make it back": This is tilt. Stop immediately.

Common Mistakes to Avoid

1. Over-trading: More trades does not equal more profit. Wait for clear edges.
2. Chasing: A market moved 20 cents. The edge was 20 cents ago, not now.
3. Ignoring fees: On fee-bearing markets (crypto 5-min/15-min), a 3% edge at p=0.50 is break-even after the 3.15% fee. Always check.
4. Correlated positions: Holding YES on "Will X happen?" and YES on "X leads to Y" is double exposure to the same event. Count it as one position.
5. Anchoring to entry price: Your entry price is irrelevant. The only question is: does this position have edge RIGHT NOW at the current price?
6. Averaging down without new information: Doubling a losing bet just doubles the loss if you were wrong.
7. Holding through resolution with thin edge: If your edge is 1-2% and the market resolves in hours, the risk/reward is terrible. Take the small loss.
