Key Takeaways (TL;DR)
• A stop-loss is a pre-planned order that automatically exits your trade at a specific price. • It is your ejector seat—it saves you from disaster when the trade goes wrong. • Set your stop BEFORE you enter the trade. Never trade without one. • A stop-loss is about protecting capital, not admitting defeat.
The Hook
Picture this: You are a fighter pilot. You have made a critical error. Your aircraft is spinning out of control toward the ground.
You have two options:
- Pull the ejector seat lever and parachute to safety.
- Stay in the cockpit, hoping you can somehow regain control before impact.
In trading, the ejector seat is called a Stop-Loss. And just like that fighter pilot, the traders who survive are the ones who are not afraid to pull it.
The Story of the Trader Who Did Not Pull the Lever
In one of our app lessons, we meet a trader who refuses to accept defeat.
The Setup: He opens a trade. The market immediately moves against him.
The Thought Process: "It will come back. I am not selling for a loss."
The Reality: The market does not come back. A $50 loss becomes a $500 loss. Then $5,000.
By the time he finally exits, his account is destroyed. He stayed in the cockpit all the way to the ground.
What is a Stop-Loss, Really?
A stop-loss is simply an automatic exit order. You tell your broker: "If the price drops to $X, sell my position immediately."
It is not a sign of weakness. It is not admitting failure. It is the single most important risk management tool in your entire trading arsenal.
How to Set a Stop-Loss
There are several methods, but the simplest approach is based on technical levels:
1. Below Key Support
If you are buying, place your stop below the nearest significant support level. If that level breaks, the trade thesis is invalid.
2. Based on Volatility
Use the Average True Range (ATR) indicator. A common rule is to set your stop at 1.5x or 2x the ATR below your entry.
3. Percentage-Based
Decide in advance that you will not lose more than 1-2% of your account on any single trade. Calculate your position size and stop-loss distance accordingly.
The Mistakes That Kill Accounts
1. "I Do Not Need a Stop"
The market does not care about your hopes. Every professional uses stops. Why would you not?
2. Moving the Stop Further Away
You set a stop at $48. The price drops to $48.50. You panic and move the stop to $46, hoping for a bounce. This is how accounts explode.
3. Mental Stops Only
"I will exit when it hits $48." But when it actually drops, emotions take over. You freeze. Set a hard stop with your broker.

What is the PRIMARY purpose of a stop-loss order?
💡 Hint: Think about what the stop-loss is designed to STOP.
Practice: Setting Your Stop-Loss
You buy at $50 with a stop at $48. The market drops to $47.
Your stop triggered at $48, limiting your loss to $2 per share. Without it, you would have lost $3 per share—50% more!
💡 Key Concept:
A stop-loss automatically exits your trade at a predetermined price. Set it before you enter—never trade without one.
