How to Set Stop-Losses? What Is Take-Profit?

Master how to set stop-loss and take-profit levels to protect capital and lock in profits

The Importance of Stop-Losses

Why Must You Use Stop-Losses?

Protect capital

• Small losses are easy to recover
• Big losses can be fatal
• As long as you keep the mountain green, you won’t run out of firewood

The asymmetry between losses and recovery

Loss	Return Needed to Break Even
-10%	+11.1%
-20%	+25%
-30%	+42.9%
-50%	+100%
-70%	+233%
-90%	+900%

Psychological Significance

• Reduce emotional interference
• Maintain objective judgment
• Avoid the “hold and hope” mindset
• Maintain trading discipline

Stop-Loss Methods

1. Percentage Stop-Loss

How to set it: stop out when the loss reaches a fixed percentage of principal

Example:

• Principal: 10,000
• Stop-loss percentage: 2%
• Stop-loss amount: 200
• Suitable for: all trading instruments

Pros and cons:

• ✅ Simple and easy to execute
• ✅ Risk is controllable
• ❌ Does not account for volatility
• ❌ May stop out too early

2. Technical Stop-Loss

Support-level stop

• Place it below an important support level
• Distance: 2–3% below support
• Basis: technical analysis

Moving-average stop

• Stop out when price breaks below a key moving average
• Common: 20-day, 50-day MA
• Suitable for: trend trading

ATR stop (Average True Range)

Stop level = Entry price - (ATR × multiple)
The multiple is usually 1.5–3

3. Time Stop-Loss

Principle: limit holding time; if the trade doesn’t play out by the deadline, stop out

Use cases:

• event-driven trading
• short-term trading
• avoid tying up capital for too long

4. Combined Stop-Loss

Combine multiple methods and take the strictest stop level:

1. Technical stop: -3%
2. Fixed-percentage stop: -2%
3. Final stop: -2% (take the smaller value)

The Art of Take-Profit

Why Is Taking Profit So Hard?

Psychological factors:

• Greed: always want more
• Regret: feel bad for selling too early
• Fear: fear missing a big move

Technical difficulties:

• Tops are hard to predict
• Trends may continue
• Taking profit too early limits profits

Take-Profit Methods

1. Target Take-Profit

Fixed return target

• Set: e.g., take profit at +20%
• Pros: clear target
• Cons: may miss a big move

Risk–reward ratio

• Set: e.g., 1:3 (risk 1 to make 3)
• Example: stop 200, target profit 600
• Suitable for: swing trading

2. Trailing Take-Profit

Trailing stop

Initial stop: Entry price -5%
After price rises 10%: move stop up to entry price
After price rises 20%: move stop up to +10%
Always keep a fixed distance from the highest price

Percent drawdown take-profit

• Take profit when price pulls back X% from the highest point
• Common: 10%–20% pullback
• Protect unrealized gains while allowing room

3. Scaling-Out Take-Profit

Pyramid take-profit

Profit +10%: sell 1/3
Profit +20%: sell 1/3
Profit +30%: sell 1/3

Core position method

• Keep 30% as a core position
• Scale out the rest
• Balance realized gains and upside participation

4. Technical Take-Profit

Resistance-level take-profit

• prior highs
• round-number levels
• Fibonacci levels

Pattern-based take-profit

• top patterns appear
• abnormal volume
• indicator divergence

Principles for Setting Stops and Targets

Reasonableness

1. Consider volatility: more volatile instruments need wider stops
2. Match the timeframe: wider for long-term, tighter for short-term
3. Align with position size: stricter for large positions; smaller positions can allow more room

Consistency

• Set before the trade; don’t change casually
• Execute strictly; don’t let emotions interfere
• Record and reflect; continuously optimize

Flexibility

• Adjust to market conditions
• Major news can be exceptions
• But you need explicit rules

Common Mistakes

Stop-Loss Mistakes

1. No stop-loss: the biggest mistake
2. Stops too tight: triggered too often
3. Moving the stop away: disguised refusal to stop out
4. “Mental stops”: weak execution

Take-Profit Mistakes

1. No take-profit plan: never take money off the table
2. Taking profit too early: small wins and out
3. Greedily never taking profit: giving back gains
4. Emotional decisions: chasing highs and selling lows

Real-World Examples

Case 1: The value of strict stop-losses

Entry: 100
Stop: 95 (-5%)
Actual move: drops to 94, then rebounds to 110

Result: stopped out and missed the rebound
Lesson: stops may miss opportunities, but they protect capital
Better approach: after stopping out, re-enter after stabilization

Case 2: Using trailing take-profit

Entry: 50
Initial stop: 47.5 (-5%)
Price rises to 60: move stop up to 55
Price rises to 65: move stop up to 58.5
Exit at 58.5 on the trailing stop

Result: locked in 17% profit
Takeaway: not the top, but a solid locked-in gain

Tools and Tips

Automation Tools

• Stop orders: trigger automatically at preset prices
• OCO orders: one triggers and the other is canceled automatically
• Alerts: price alerts to support decision-making

Psychological Training

1. Accept losses: stop-loss is a cost, not a failure
2. Overcome greed: taking profit is also a win
3. Maintain discipline: rules beat feelings
4. Think long term: one trade doesn’t matter much

Summary

Stop-loss and take-profit are the lifeline of trading:

• Stop-loss: control risk and protect capital
• Take-profit: lock in gains and bank profits
• Balance: find the balance between protection and opportunity
• Discipline: execution matters more than strategy

Remember: there is no perfect stop-loss/take-profit strategy—only the method that fits you best. Keep learning, summarizing, and optimizing to form your own trading system.
