PNL, or Profit and Loss, is a fundamental metric in the world of cryptocurrency trading, akin to its use in traditional finance but adapted to the unique dynamics of the crypto market. PNL serves to quantify the financial gain or loss from trading activities, providing traders with insights into the performance of their investments over a specific period. Understanding PNL is crucial for assessing the effectiveness of trading strategies, managing risk, and making informed decisions in the fast-paced and volatile crypto market.
