name: polymarket-nordic-trader description: Trades Polymarket prediction markets focused on Scandinavian and Nordic events — Swedish politics, Norwegian economy, Danish infrastructure, Nordic business milestones (Spotify, Northvolt, Klarna), local weather extremes, and regional sports outcomes.

Nordic & Scandinavian Trader

This is a template.
The default signal is keyword discovery + Swedish/Nordic news feed monitoring — remix it with Riksdagen API for legislative tracking, SCB (Statistics Sweden) data releases, Affärsvärlden market feeds, or Spotify investor relations signals.
The skill handles all the plumbing (market discovery, trade execution, safeguards). Your agent provides the alpha.

Strategy Overview

Nordic markets are one of the most underserved categories on global prediction platforms. Traders with genuine local knowledge — Swedish politics, Scandinavian business news, Nordic weather patterns — hold structural information advantages over global retail traders.

This skill trades:

• Swedish politics — Government formation, Riksdag legislative milestones
• Nordic business — Spotify profitability, Northvolt recovery, Klarna/unicorn IPOs
• Infrastructure — Förbifart Stockholm, Malmö Arena, high-speed rail announcements
• Sports — Champions League Nordic teams, Swedish/Norwegian international competitions
• Local weather — Stockholm heatwaves, Öresund ice crossing, Oslo snowfall records
• Culture — Melodifestivalen viewership, Way Out West attendance

Key edge: the vast majority of Polymarket liquidity is US/global retail. Nordic-specific markets will have mispriced odds whenever the resolver requires local knowledge.

Signal Logic

Default Signal: Nordic News Feed + Market Mismatch

1. Discover markets mentioning Nordic/Scandinavian keywords
2. Monitor Swedish/Nordic RSS feeds: SVT, Aftonbladet, Di.se, Affärsvärlden
3. Check local weather data from SMHI (Swedish Meteorological Institute) for weather markets
4. Compare current news consensus with market price
5. Enter when the global market clearly hasn't incorporated locally-obvious information

Remix Ideas

• SMHI API: https://www.smhi.se/klimatdata — Official Swedish weather data
• Riksdagen API: https://data.riksdagen.se/ — Parliamentary voting and legislation tracking
• SCB (Statistics Sweden): https://www.scb.se/en/ — Economic data releases
• Avanza/Nordnet: Swedish stock sentiment as proxy for Spotify/Nordic tech markets
• Allsvenskan data: Football results and standings for sports markets

Risk Parameters

Parameter	Default	Notes
Max position size	$20 USDC	Nordic markets may be illiquid
Min market volume	$1,000	Accept lower liquidity for edge opportunity
Max bid-ask spread	20%	Niche markets have wider spreads
Min days to resolution	3	Local events can resolve quickly
Max open positions	8	Diversify across Nordic themes

Local Knowledge Edge

Information Advantage Examples

• Förbifart Stockholm: A Swedish civil engineer knows the tunnel's actual completion status better than US retail traders
• Northvolt bankruptcy: Swedish business press covered the restructuring in detail months before English-language coverage
• SMHI winter forecasts: Local seasonal weather outlooks are published in Swedish first
• Melodifestivalen: SVT viewership trends visible to Swedish residents immediately

Timing Edge

Swedish/Nordic news typically breaks in CET timezone (UTC+1/+2). US-dominated Polymarket markets take 2–6 hours to reprice on Nordic news.

Key Data Sources

• SMHI (Weather): https://www.smhi.se/
• Riksdagen (Parliament): https://data.riksdagen.se/
• SCB (Statistics): https://www.scb.se/
• SVT Nyheter: https://www.svt.se/nyheter/
• Di.se (Business): https://www.di.se/

Installation & Setup

clawhub install polymarket-nordic-trader

Requires: SIMMER_API_KEY environment variable.

Cron Schedule

Runs every 15 minutes (*/15 * * * *). Nordic events follow business hours (CET); tighter polling during 06:00–22:00 CET recommended in remixes.

Safety & Execution Mode

The skill defaults to paper trading (venue="sim"). Real trades only execute when --live is passed explicitly.

Scenario	Mode	Financial risk
python trader.py	Paper (sim)	None
Cron / automaton	Paper (sim)	None
python trader.py --live	Live (polymarket)	Real USDC

The automaton cron is set to null — it does not run on a schedule until you configure it in the Simmer UI. autostart: false means it won't start automatically on install.

Required Credentials

Variable	Required	Notes
SIMMER_API_KEY	Yes	Trading authority — keep this credential private. Do not place a live-capable key in any environment where automated code could call --live.

Tunables (Risk Parameters)

All risk parameters are declared in clawhub.json as tunables and adjustable from the Simmer UI without code changes. They use SIMMER_-prefixed env vars so apply_skill_config() can load them securely.

Variable	Default	Purpose
SIMMER_NORDIC_MAX_POSITION	20	Max USDC per trade
SIMMER_NORDIC_MIN_VOLUME	1000	Min market volume filter (USD)
SIMMER_NORDIC_MAX_SPREAD	0.20	Max bid-ask spread (0.10 = 10%)
SIMMER_NORDIC_MIN_DAYS	3	Min days until market resolves
SIMMER_NORDIC_MAX_POSITIONS	8	Max concurrent open positions
