# Market Comparison

> Compare up to 4 markets side-by-side with synchronized price charts and key metrics.

# 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                                                                 |

<Tip>
  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.
