Trading strategy mistakes often happen when traders rush decisions or ignore basic risk management. Common errors include overtrading, entering positions without a clear plan, or chasing quick profits based on emotions like fear or greed. Many also risk too much capital on a single trade or forget to set stop-loss orders, which protect against unexpected market moves. Another frequent mistake is relying only on one strategy without adapting to changing market conditions. Staying disciplined, using proper risk management, and keeping emotions in check help avoid these common trading pitfalls.
