The stop-loss is the single most important tool a beginner can adopt. Here’s how it works and how to place one properly.

A stop-loss is a pre-set order that exits your trade automatically once price hits a level you choose — capping your loss so no single trade can hurt you badly.

The stop-loss exits automatically, so a small planned loss never becomes a large one.

Why every trade needs one

Without a stop, a small loss can snowball while you “hope” it recovers. A stop turns risk into a known, fixed number you decided in advance.

How to place one sensibly

  • Put it where your trade idea is proven wrong — e.g., below support.
  • Not so tight that normal noise stops you out; not so wide that the loss is huge.
  • Size your position from the stop distance.
Key idea: Set your stop before you enter, and never move it further away to avoid taking a loss. That one rule saves accounts.

Trailing stops

As a trade moves your way, a trailing stop follows price to lock in profit while giving the trade room to run.

Key takeaways

  • A stop-loss caps your loss automatically.
  • Place it where your idea is proven wrong.
  • Never widen a stop to avoid a loss.
  • Trail your stop to protect profits.

Frequently asked questions

Where should I place my stop-loss?

At the level where your trade idea is proven wrong — often just beyond support/resistance — balancing noise against loss size.

Should I use a stop-loss on every trade?

Yes. It converts an unknown risk into a fixed, pre-decided number and prevents small losses from snowballing.

What is a trailing stop-loss?

A stop that follows price as a trade moves in your favour, locking in profit while letting the trade run.
