in trading reflects your financial performance over a specific period. It tracks realized gains/losses from closed trades and unrealized PnL from open positions. A positive PnL means profitability, while negative indicates losses. Key factors affecting PnL include trade execution, risk management, market volatility, and strategy effectiveness. Consistent PnL growth requires discipline—cutting losses quickly and letting winners run. Reviewing PnL helps refine strategies, identify strengths/weaknesses, and improve decision-making. Traders often measure PnL as a percentage of capital to assess performance objectively. Whether scalping, swinging, or investing, tracking PnL is essential for long-term success.
