Auto Trading Winner

Cross-venue trading skill for ClawHub that supports both manual candidate selection and unattended auto mode, while filtering markets by price band and trading volume.

This skill scans markets on sim, polymarket, or kalshi, filters for markets priced in a configurable middle band, ranks them by trading volume, and supports both manual selection and unattended auto mode.

This is a template. The default signal is simple volume ranking plus a price-band filter. Remix it with your own alpha, liquidity rules, timing rules, or fair-value model. The skill handles market discovery, venue-specific indexing, context checks, sizing, and trade execution plumbing.

What It Does

On each run, the skill:

1. Calls auto_redeem().
2. Discovers markets for the configured venue.
3. Filters markets to a configurable YES price band, default 30% to 70%.
4. Sorts the remaining markets by trading volume.
5. Builds a ranked candidate pool and highlights the top 5 by default.
6. Prints the shortlist for review.
7. In RUN_MODE=manual, lets you manually select one candidate.
8. In RUN_MODE=auto, starts from rank 1 automatically unless SELECT_CANDIDATE is provided.
9. If the chosen candidate fails indexing or safeguard checks, falls through to the next ranked candidate in the full ranked pool automatically.
10. Checks context safeguards before trading.
11. Sizes the trade with simmer_sdk.sizing.size_position().
12. Defaults to dry-run unless you explicitly pass --live.

Required Files

This skill follows Simmer's manual ClawHub pattern:

• SKILL.md
• clawhub.json
• trade_skill.py

Environment Variables

Credentials

• SIMMER_API_KEY (required): Your Simmer API key.
• SOLANA_PRIVATE_KEY (optional): Needed only for live Kalshi self-custody trading.
• WALLET_PRIVATE_KEY (optional): Needed only if your Polymarket setup uses an external wallet flow.

Strategy Config

• TRADING_VENUE: sim, kalshi, or polymarket. Default: sim
• RUN_MODE: manual or auto. Default: manual
• MARKET_QUERY: Optional query term used during discovery. Default: empty string.
• MIN_PRICE: Minimum YES price allowed. Default: 0.30
• MAX_PRICE: Maximum YES price allowed. Default: 0.70
• MAX_MARKETS: Maximum number of discovered markets to inspect before ranking. Default: 50
• CANDIDATE_LIMIT: Number of ranked candidates to show. Default: 5
• FAIR_PROBABILITY: Fair YES probability used for sizing and side selection. Default: 0.55
• MIN_EDGE: Minimum edge required before trading. Default: 0.03
• MAX_SLIPPAGE_PCT: Skip trades if estimated slippage exceeds this threshold. Default: 0.15
• SIMMER_ENABLE_LIVE: Set to true to allow live order placement. Default: false
• SELECT_CANDIDATE: Optional 1-based index of the candidate to trade in non-interactive runs.
• AUTO_CONFIRM_LIVE: Optional explicit override required if you want RUN_MODE=auto together with live execution on kalshi or polymarket. Default: false

Safety Model

• Dry-run is the default.
• Every trade is tagged with source and skill_slug.
• Every trade includes public reasoning.
• Market context is checked before order placement.
• Position sizing uses bankroll and edge, not a fixed stake.
• Kalshi markets use Simmer's check-then-import indexing path before trading.
• RUN_MODE=manual is the default for all venues.
• RUN_MODE=auto makes the skill non-interactive and starts from the top-ranked candidate.
• Automatic live execution on kalshi and polymarket requires an explicit AUTO_CONFIRM_LIVE=true override.
• If the selected candidate fails, the skill tries later ranked candidates automatically.

Local Usage

Review candidates without trading:

bash

export SIMMER_API_KEY="sk_live_..."

bash

export SELECT_CANDIDATE="2"
python trade_skill.py --live

Unattended dry-run from the highest-ranked candidate:

bash

export TRADING_VENUE="kalshi"
export RUN_MODE="auto"
python trade_skill.py

Fully unattended paper-trading run on sim:

bash

export TRADING_VENUE="sim"
export RUN_MODE="auto"
export SIMMER_ENABLE_LIVE="true"
python trade_skill.py

Interactive review:

Remix Ideas

• Replace the volume ranking with your own score.
• Add time-to-resolution filters.
• Use venue-specific volume thresholds.
• Add per-category or per-market fair values.
• Expand manual selection into a multi-pick workflow.
