# PnL Calculation

Understanding Profit and Loss (PnL) is crucial to managing investments and making informed decisions. Traders have insight into the PnL of their past trades in the 'History' tab of their portfolio page at <https://trade.bluefin.io/portfolio/history>. &#x20;

**Unrealized PnL**: The profit and loss not yet realized from an open position. It is calculated as the difference between the entry and current mid-market prices multiplied by the position quantity.

$$\text{Unrealized PnL} = \begin{cases} \text{Position Size}\times \big(\text{Mid-Market Price} - \text{Entry Price}\big) \quad &\text{if Long}, \ \text{Position Size}\times \big(\text{Entry Price} - \text{Mid-Market Price}\big) \quad &\text{if Short}.\end{cases}$$

**Realized PnL**: The profit and loss that has already been realized from partially or fully closing the position. It is calculated as the difference between the entry and exit prices multiplied by the quantity closed.&#x20;

$$\text{Realized PnL} = \begin{cases} \text{Size Closed}\times \big(\text{Exit Price} - \text{Entry Price}\big)  \quad &\text{if Long}, \ \text{Size Closed}\times \big(\text{Entry Price} - \text{Exit Price}\big)   \quad &\text{if Short}.\end{cases}$$
