Signal feed

The Signals tab in the Markets terminal shows a dedicated feed of all markets where the AI has found a meaningful divergence from the current price. Unlike the AI Pick badges on market cards (which are just indicators), the signal feed shows full signal data with rich filtering.

​

Signal card anatomy

Each SignalFeedCard displays:

​

Card animations

• Dealt layout: Cards cascade from the top with spring physics (stagger delay per card)
• Grid layout: Cards fade in with scale-up animation
• Hover: Card lifts with shadow enhancement

​

Filters

The signal feed has independent filters at the top:

​

Signal type filter

​

Category filter

Dropdown with all available market categories. Filters signals to only show markets in the selected category.

​

Info modal

A ”?” button that opens an explanatory modal describing each signal type in detail.

​

Sorting

​

Pagination

The signal feed uses cursor-based infinite pagination:

• Page size: 50 signals per page
• Cursor format: {confidence}:{condition_id} for stable ordering
• More signals load as you scroll near the bottom
• Total signal count displayed at the top

​

Data pipeline

The signal feed has its own data pipeline:

1. API: GET /api/signals/feed with query params for all filters
2. Server: Queries market_signals table, joins with market_catalog for enrichment
3. Caching: 2-minute server-side cache on the feed (skipped for cursor requests), 5-minute cache on total count
4. Post-filtering: Tags (OR match), keyword search, date range, minimum volume, sentiment, trending status are all applied after the initial query
5. Hook: useSignalFeed manages the infinite query state, parses results, memoizes for performance
6. Enrichment: Each signal is enriched with live prices from the SSE price pool

​

Signal data model

Each signal contains: The feed API enriches each signal with live market data: question, category, live YES/NO prices (from SSE), volume, 24h volume, liquidity, and end date.
