重點摘要

Maximum Daily Loss is the maximum amount your account can lose in a single trading day. Recommended setting: 2-3% of total capital. Correct action when triggered: immediately stop all trading for the day, step away from the computer to cool down, reassess the next day. This mechanism prevents emotional revenge trading after consecutive losses and is the most important safety valve for capital protection.

Core Definition of Maximum Daily Loss

Maximum Daily Loss is the maximum amount or percentage your account can lose by the end of each trading day.

This is a safety valve that prevents you from making more poor decisions when your emotions are off. It is like a seatbelt in a car - you do not drive recklessly just because you have a seatbelt, but it protects you when an accident happens. All strategies in the Strategy Center have built-in automatic stop-losses, providing your first layer of protection.


How to Set a Reasonable Daily Loss Limit?

Account SizeRecommended LimitDescription
< $100K3%More flexible
$100K-$500K2%Moderate
> $500K1-1.5%Conservative

Setting principle: This number should be an amount you can calmly accept even if you lose it, without feeling the urge to win it back.


Correct Handling When Triggered

Step 1: Immediately Stop Trading

No matter how many good opportunities remain, immediately stop all trading for the day. Do not think just one more trade to win it back.

Step 2: Step Away from the Computer

Go for a walk, exercise, do anything unrelated to trading. Give your brain at least 15 minutes of cooling-off time.

Step 3: Record the Cause

Write down the reason for today loss:

  • Was it a strategy signal issue?
  • Was it an execution discipline issue?
  • Or just bad luck?

Step 4: Reassess the Next Day

Only after calming down the next day should you reassess the market. For more on mindset adjustment after losses, see The Right Mindset During a Losing Streak.


Common Mistakes

Mistake 1: Continuing to Trade After Trigger

Thinking just one more trade to win it back, only to lose more. Remember: trigger the limit = stop immediately, no exceptions.

Mistake 2: Setting the Limit Too High

A 10-20% limit provides no protection at all. The purpose of a limit is protection, not challenge.

Mistake 3: Revenge Trading the Next Day

Yesterday loss is over - do not bring emotions into the new day. Every day is a fresh start.


Summary

Key principles of daily loss limits:

  1. Set at 2-3% - this is the maximum you can calmly accept, and can be adjusted based on market conditions through Regime and Risk analysis
  2. Stop when triggered - no exceptions
  3. Record the cause - a trading journal is a tool for improvement
  4. Start fresh the next day - do not bring emotions into the new trading day
