Daily Loss Limits & Circuit Breakers

What Are Daily Loss Limits?

Daily loss limits define the maximum amount an EA is allowed to lose in a single trading day. Once the threshold is reached, the system stops trading to prevent emotional or algorithmic over‑reaction.

• • Hard cap on daily drawdown
• • Automatic shutdown after limit is hit
• • Prevents revenge trading
• • Protects equity during volatile sessions

What Are Circuit Breakers?

Circuit breakers are emergency mechanisms that pause trading when abnormal conditions occur. They act as a safety net when volatility or execution quality becomes dangerous.

• • Volatility spikes
• • Spread widening
• • Liquidity collapse
• • Rapid equity drops

Why These Mechanisms Matter

Without daily limits and circuit breakers, even strong strategies can suffer catastrophic losses during extreme market conditions. These mechanisms ensure long‑term survival.

Key Benefits

• • Prevents cascading losses
• • Protects against black‑swan events
• • Stabilizes long‑term equity curve
• • Reduces emotional interference
