Kalshi Paper Trading

Use this skill for Kalshi paper execution and ledger management.

Kalshi-native paper trading should use a dedicated ledger and CLI rather than the generic paper-trading skill.

When to Use

Use this skill when the user wants to:

• design or build a Kalshi-specific paper trader
• inspect or reconcile Kalshi paper positions
• store Kalshi prices correctly in cents without mixing units
• compute Kalshi realized and unrealized PnL
• add Kalshi-native exposure or risk rules

Key Rule

Do not route Kalshi paper executions through the generic skills/paper-trading ledger unless the user explicitly asks to keep that compatibility.

Default assumptions for this skill:

• Kalshi execution prices are stored as integer cents in [0, 100]
• settlement is 100 or 0 cents
• positions are keyed by market_ticker + contract_side
• risk controls are based on premium and event exposure, not stop-distance percent risk
• live market sync supports both legacy cent fields and modern Kalshi *_dollars quote fields

Primary Commands

Initialize the paper account:

node --experimental-strip-types {baseDir}/scripts/kalshi_paper.ts init --account kalshi --starting-balance-usd 1000

Check status:

node --experimental-strip-types {baseDir}/scripts/kalshi_paper.ts status --account kalshi --format json --pretty

Sync a live market quote into the ledger:

node --experimental-strip-types {baseDir}/scripts/kalshi_paper.ts sync-market --market <TICKER> --format json --pretty

Open a paper trade from the live Kalshi ask:

node --experimental-strip-types {baseDir}/scripts/kalshi_paper.ts buy-from-market --account kalshi --market <TICKER> --side YES --contracts 1 --format json --pretty

Reconcile a finalized market:

node --experimental-strip-types {baseDir}/scripts/kalshi_paper.ts reconcile --account kalshi --market <TICKER> --winning-side YES

Review account performance:

node --experimental-strip-types {baseDir}/scripts/kalshi_paper.ts review --account kalshi --format json --pretty

Integration

Pair this skill with a separate Kalshi API read skill for:

• market discovery
• liquidity validation
• trades and orderbook checks
• pre-trade candidate ranking

This skill owns the paper ledger and execution side only.

Design Reference

Read the proposal before making structural changes:

• references/kalshi-paper-ledger.md

Use that document for:

• schema design
• command surface
• valuation rules
• settlement logic
• migration plan away from the generic paper trader

Tests

Run the Kalshi paper-trader test file:

node --test {baseDir}/tests/kalshi_paper.test.mjs
