What is a Stop-Loss?
A stop-loss order is an instruction to your broker to automatically close your position when price reaches a specific level. It's your primary risk management tool—the safety net that prevents small losses from becoming account-destroying disasters.
Example: You buy EUR/USD at 1.1000. You set a stop-loss at 1.0950 (50 pips below). If price drops to 1.0950, your position closes automatically, limiting your loss to 50 pips.
Types of Stop-Loss Orders
| Type | Description | Best For |
|---|---|---|
| Fixed Stop-Loss | Set at a specific price, doesn't move | Most traders |
| Trailing Stop | Follows price at set distance, locks profits | Trend trading |
| Guaranteed Stop | Protects against slippage/gaps (premium fee) | High-risk events |
| Mental Stop | You manually close (not recommended) | Experienced only |
Stop-Loss Placement Strategies
- Below Support: For buy positions, place stop below recent support level.
- Above Resistance: For sell positions, place stop above recent resistance.
- ATR-Based: Use Average True Range (1.5-2x ATR) for volatility-adjusted stops.
- Swing Low/High: Place below/above the most recent swing point.
- Add Buffer: Add 5-10 pips buffer to avoid stop-hunting wicks.
Calculating Stop-Loss Distance
The 1-2% rule: Never risk more than 1-2% of your account on a single trade.
Formula:
Position Size = (Account × Risk%) / (Stop Distance × Pip Value)
Example: $10,000 account, 1% risk = $100 max loss. If stop is 50 pips and pip value is $1/pip, max 2 mini lots.
Common Stop-Loss Mistakes
- Too Tight: Stopped out by normal market noise.
- Too Wide: Losses larger than your risk tolerance.
- Moving Stop Wider: Never move stop away from price to "give it room."
- No Stop at All: Recipe for blown accounts.
- Same Pips Every Trade: Ignore market structure and volatility.
Frequently Asked Questions
What is a stop-loss in forex?
An order to automatically close your position at a specified price to limit potential losses.
Where should I place my stop-loss?
Below support for buys, above resistance for sells. Add buffer room for wicks.
How many pips should my stop-loss be?
Depends on volatility and timeframe. Use ATR or technical levels, not arbitrary pips.
What is a trailing stop?
A stop-loss that follows price at a fixed distance, locking in profits as trade moves in your favor.
Can stop-loss slip?
Yes. During gaps or high volatility, your stop may execute at a worse price. Guaranteed stops prevent this.
What is a guaranteed stop-loss?
A stop that guarantees execution at your price regardless of gaps. Costs extra (premium or wider spread).
Should I always use stop-loss?
Yes. Trading without stops is gambling, not trading. Protect your capital.
What is stop hunting?
When price briefly reaches stop-loss levels before reversing. Common at obvious support/resistance.
Can I move my stop-loss?
Only to lock in profits (move it closer). Never move it further away to "give trade room."
What is breakeven stop?
Moving stop-loss to entry price once trade is in profit. Ensures no loss on that trade.
How do I calculate position size from stop-loss?
Position Size = (Account Risk $) / (Stop Pips × Pip Value). Risk 1-2% of account.
Does my broker see my stop-loss?
Yes. Your broker and their liquidity providers can see pending orders. This is normal and necessary for execution.
