Gold can move quickly
XAU/USD can react sharply to liquidity changes, economic releases, geopolitical events, and shifts in interest-rate expectations. A rule that behaved calmly in one period may encounter different conditions later.
Risk instructions need boundaries
Position sizing, protective stops, invalidation rules, session limits, and maximum acceptable exposure should be selected before an automated order is allowed to act.
- Use exposure that remains tolerable during a losing sequence
- Do not increase size to recover a previous loss
- Treat leverage as additional risk rather than additional certainty
- Review what happens during gaps or interrupted execution
Monitoring remains necessary
Automation should be checked after software updates, broker changes, connection interruptions, unusual spreads, and market conditions outside the assumptions used when configuring the system.
