# Trader Category PnL

> Get notified when a trader's per-category PnL crosses a configured threshold.

<Note>
  **Event:** `trader_category_pnl` \
  **Endpoint:** `wss://api.struct.to/ws/alerts` \
  **Cost:** 0.1 credits per event
</Note>

Fires when a trader's profit and loss aggregated across all markets in a given category (for example politics, sports, or crypto) crosses the configured thresholds. This is useful for tracking how a wallet performs within a specific category rather than across its whole portfolio or a single market.
