Stop-Loss Mastery

In one line: Before you buy, decide where you will get out if you are wrong β€” and never move that exit further away.

🎯 What you'll learn

  • What a stop-loss is, and why every trade needs one.
  • WHERE to place your stop, not just any random price.
  • The main types of stop-loss, in simple words.
  • The one rule you must never break.

πŸ“˜ Key concepts

What is a stop-loss?

A stop-loss is a plan to exit a losing trade before it hurts too much.

  • Stop-loss (a fixed exit price that caps your loss) is decided BEFORE you enter the trade.
  • Think of it like the brakes in a car. You do not wait for the wall to stop β€” you brake early.
  • It answers one question: "If I am wrong, at what price do I admit it and leave?"
  • Deciding this early keeps emotion out. In the heat of the moment, fear and hope make bad choices.

Where to place the stop

Place your stop beyond a meaningful level, not at a random number.

  • For a long (a buy trade, hoping price goes up): put the stop below support (a price level where buyers often step in) or below the recent swing low (the lowest point of the last dip).
  • For a short (a sell trade, hoping price goes down): put the stop above resistance (a price level where sellers often step in).
  • Do not use a round number like exactly β‚Ή100 just because it looks neat.
  • Do not place it too tight. Normal noise (small up-down wiggles in price) can knock you out too early.
  • Give the stop breathing room. Then control your money risk with position size (how many shares you buy) β€” not by moving the stop.

Types of stop-loss

There are a few common ways to set a stop.

  • Fixed stop: a set amount or percent, like "exit if price drops 5%."
  • Structure-based stop: placed below support or the swing low. Usually the best choice.
  • ATR-based stop: based on ATR (Average True Range β€” a number that measures how much price normally moves). More movement, wider stop.
  • Trailing stop: starts below price, then moves up as price rises. It locks in profit but never moves down.

Hard stop vs mental stop

Use a real order, not a promise to yourself.

  • Hard stop: an actual stop order placed with your broker. It fires automatically.
  • Mental stop: a level you keep only in your head. In real life, fear makes you ignore it.
  • Always prefer a hard stop. Machines do not panic. Humans do.

πŸ” Example

You buy a share at β‚Ή100. Support sits at β‚Ή95, so you place your stop just below, at β‚Ή94.

   Buy here ---> 100
                  |
   Stop below --> 94   (just under support at 95)
  • Your risk per share is β‚Ή100 βˆ’ β‚Ή94 = β‚Ή6.
  • You decide to risk only β‚Ή600 total on this trade.
  • So you buy 100 shares (β‚Ή600 Γ· β‚Ή6 = 100 shares).
  • If price hits β‚Ή94, you are out. Loss = β‚Ή600. Planned and small.
  • Notice: you kept risk small by buying fewer shares, NOT by moving the stop closer.

⚠️ Common mistakes

  • Moving the stop wider when price falls, hoping it comes back. This is the cardinal sin. A small loss becomes a huge one.
  • Using a mental stop and then ignoring it when fear hits.
  • Placing the stop too tight, so normal noise triggers it again and again.
  • Placing it at a round number instead of below real support.
  • Trading with no stop at all β€” one bad day can wipe out weeks of gains.

βœ… Key takeaways

  • Decide your exit before you enter, never after.
  • Place the stop beyond a real level (support or swing low), with some room.
  • Keep money risk small by adjusting position size, not by tightening the stop.
  • Never move a stop further away to avoid a loss.
  • Use a hard stop order, not a mental one.

πŸ“ Quick check

  1. Q: You are long and price is falling toward your stop. Should you move the stop lower to give it more room? A: No. Never move a stop wider to avoid a loss. Take the small planned loss.
  2. Q: You want to buy but the safe stop is far away, making the risk big. What do you change? A: Your position size. Buy fewer shares so the money risk stays small.
  3. Q: Why is a hard stop better than a mental stop? A: It fires automatically, so fear or hope cannot make you ignore it.
