Rage is one of the only onchain perps to allow users withdraw their unrealized PnL (via Free Collateral). To calculate the unrealized PnL of a trade position:
Unrealized PnL = Token Position * (Current Price - Entry Price)
The hisotrical realized PnL can be calculated by exporting a CSV of your historical trades and summing the average open and close value of your trades chronologically.
Account value is the combination of your margin deposits, margin withdrawals, and realized/unrealized PnL. It is displayed on the main trading interface and can be used to derive your unrealized/realized PnL.
Account Value = Deposits - Withdrawals + Realized PnL + Unrealized PnL
