# PnL in Your App

Accurate PnL data is core to every feature in a social trading app and in the Clicker API: position tracking, profiles, and trader discovery.

## Positions

Users get full context on a trader's position in a specific token - whether they're fully in or out, their cost basis, and how profitable they are.

## Profiles

Users can view a trader's current open positions and historical best PnL positions, along with aggregate PnL metrics.

## Tokens

Users can discover top position holders on any token - not just wallet addresses, but real traders with identities - along with live PnL on those positions.

## Leaderboards

Ranked traders across various categories like Base, Solana, Ethereum, and Perps.
