In cryptocurrency, PnL stands for Profit and Loss. It's a metric used to assess the financial performance of cryptocurrency investments or trading positions. Essentially, it shows whether a trader or investor has made a profit or incurred a loss from their crypto holdings.

Here's a breakdown:

Realized PnL: This refers to the profit or loss from closed trades or positions. It's the actual money made or lost when you sell an asset.

Unrealized PnL: This represents the potential profit or loss on your open positions based on the current market price, but without actually selling the asset.

Calculating PnL:

For a single trade: PnL = Selling Price - Buying Price.

For a long position (buying low and selling high): (Current Price - Entry Price) * Position Size * Contract Multiplier.

For a short position (selling high and buying low): [(1 / Current Price) - (1 / Entry Price)] * Position Size * Contract Multiplier.

Importance of PnL:
