Common trading strategy mistakes include:

1. *Lack of clear goals*: Not defining trading objectives and risk tolerance.

2. *Insufficient risk management*: Failing to set stop-losses or manage position sizes.

3. *Overtrading*: Excessive buying and selling, leading to increased costs and reduced performance.

4. *Emotional decision-making*: Letting emotions dictate trading decisions, rather than sticking to a strategy.

5. *Inadequate research*: Not thoroughly understanding markets, assets, or trading strategies.

6. *Failure to adapt*: Not adjusting strategies to changing market conditions.

7. *Overreliance on indicators*: Relying too heavily on technical indicators without considering other factors.

To avoid these mistakes, focus on developing a solid trading plan, managing risk, and staying disciplined. Do you have specific questions about trading strategies or risk management?
