Market comparison
The comparison tool lets you overlay up to 4 markets on a single view to spot divergences, correlations, and relative value.
How to access
Navigate to /markets/compare or use the comparison mode from the trading store. Markets can be added to comparison via the market detail panel or directly from the comparison page.
Comparison view
The ComparisonView component renders:
Market picker
An autocomplete search input powered by MarketPicker:
- Type to search (debounced) — queries
/api/markets?search=...&limit=10
- Results show: market question, current price %, and volume
- Already-selected markets are excluded from results
- Click to add to comparison (up to 4 max)
Side-by-side display
Each selected market shows:
- Market question
- Current YES/NO prices
- Volume, liquidity, and 24h change
- Resolution date
- AI signal (if present)
Synchronized price charts
All selected markets render on overlaid or stacked price charts using TradingView’s lightweight-charts:
- Same timeframe for all markets
- Color-differentiated lines
- Hover crosshair syncs across charts
- Timeframe toggle (6H, 1D, 1W, 1M, ALL)
Use cases
| Scenario | Example |
|---|
| Correlated outcomes | ”BTC above 100K by June” vs “BTC above 80K by June” — if the 100K market is priced higher than the 80K market, something is wrong |
| Same event, different angles | ”Democrats win Senate” vs “Democrats win popular vote” — should the popular vote winner also win the Senate? |
| Cross-category correlation | A crypto market vs a policy market — does regulatory action correlate with price action? |
| Arbitrage detection | Two markets on essentially the same outcome with different prices |
Comparison is most powerful in Stacked View. Find an event group, expand it, then compare the sub-markets that seem mispriced relative to each other.
