# Copytrading and social trading

Find traders worth following, show their track record, and track their positions and fills.

Copytrading and social trading apps usually need to:

* find high-signal traders to show your users
* show each trader's track record
* track the live positions and orders of the traders your users follow
* monitor the fills and orders of your own users

#### Finding high-signal traders

One of the potential ways to find high-signal traders on Hyperliquid is to use the [perpSnapshots](/readme/rest-api/market-data/perpsnapshot.md) endpoint to find large positions on any market. These could be presented to your users later.

You can also rank traders by realized PnL, win rate or volume with [userPnlLeaderboard](/readme/rest-api/user-performance/userpnlleaderboard.md), and show a trader's track record with [userPnlSummary](/readme/rest-api/user-performance/userpnlsummary.md) and [userCompletedTrades](/readme/rest-api/user-performance/usercompletedtrades.md).

#### Tracking live positioning and orders

After your users have found and followed a set of initial traders, you would be able to get positioning updates from all these accounts by calling [batchClearinghouseStates](/readme/rest-api/user-position-data/batchclearinghousestates.md) (set `dex` to `"ALL_DEXES"` to include HIP-3 positions). You can also subscribe to multiple users' orders through the [userOrderUpdates](/readme/websocket/user-data/userorderupdates.md) websocket.

#### Monitoring the fills and order updates of your users

You can monitor all fills of your users by subscribing to the [builderFills](/readme/websocket/builder-data/builderfills.md) websocket. Alternatively, you can query the [builderFillsByTime](/readme/rest-api/historical-data/builderfillsbytime.md) API to get all fills done through your builder code.\

Subscribing to [builderOrderUpdates](/readme/websocket/builder-data/builderorderupdates.md) will allow you to monitor your users' addresses by tracking all orders of users utilizing your builder code.
