Close Positions

PnL calculation

The frontend surfaces a simulated PnL based on the entry price, current price, leverage ratio, accrued interest and the fees. There can be slight mismatch for realized PnL at position closing, since there can be price impact, which is slippage protected.

Residual

Due to the nature of AMM math, the exact resulting price point after the swap can be diffuclt to track. As a result, at the position closing, there may be a small residual of the position token left (e.g., WETH, if the trader is using USDC to long WETH). Such residual is returned to the trader wallet at position closing. The trader may choose to swap into the source token (e.g., USDC) afterwards.
