Trader exposure represents the total risk faced by individual traders or trading desks from their open positions across all instruments and markets. This comprehensive risk measure includes market exposure, concentration risk, and correlation effects between different positions. Monitoring trader exposure helps manage risk and prevent excessive losses.

Trader exposure assessment involves position sizing, value-at-risk calculations, stress testing, and correlation analysis to understand total risk profile. Risk limits and exposure monitoring help prevent individual traders from taking excessive risks that could threaten firm capital. Understanding exposure management helps optimize risk-adjusted returns.

Real-world example: A commodity trader shows $5 million total exposure across crude oil, natural gas, and gold positions, with risk management systems monitoring this exposure against firm limits and margin requirements.
