Most new traders lose to the same handful of mistakes. Avoid these and you’re already ahead of the pack.

The 12 mistakes

  1. Trading without a plan.
  2. No stop-loss.
  3. Position sizes too large.
  4. Revenge trading after a loss.
  5. Chasing hot tips.
  6. Averaging down on losers.
  7. Overtrading.
  8. Ignoring risk/reward.
  9. Using too much leverage.
  10. No journal or review.
  11. Letting emotion decide.
  12. Skipping practice and going straight to real money.
Key idea: Notice how few of these are about picking the right stock. Trading is won or lost on discipline and risk, not stock-picking genius.
Stop-loss capping a loss
The simplest fix for the deadliest mistakes: a stop-loss on every trade.

The one habit that fixes most of them

Trade a written plan on a simulator until it’s automatic. Practice turns “I know I shouldn’t” into “I don’t.”

Key takeaways

  • Most losses come from a few repeated mistakes.
  • The deadliest: no stop, oversizing, revenge trading.
  • Discipline beats stock-picking.
  • Practise a written plan until it’s second nature.

Frequently asked questions

Why do most beginner traders lose money?

Usually not from bad stock picks but from poor risk management — no stop-loss, oversized positions and emotional decisions.

What is revenge trading?

Placing impulsive trades to "win back" a loss. It abandons your plan and usually deepens the damage.

How can I stop making trading mistakes?

Trade a written plan on a simulator until following it is automatic, and journal every trade to catch repeating errors.
