Stop Loss Strategies Every Trader Must Know

A stop loss is your most important line of defense in trading. It's the order that limits your losses when trades don't work out. Yet many traders either don't use stop losses or place them poorly, leading to devastating account losses.

This guide covers everything you need to know about stop losses—different types, placement methods, and strategies to protect your capital while giving your trades room to work.

Why Stop Losses Are Non-Negotiable

The Mathematics of Survival

Without stop losses, you cannot control your risk:

Scenario A: No Stop Loss

• Trade goes wrong
• You hope it comes back
• Loss grows: 10%, 20%, 50%+
• Account devastating

Scenario B: With Stop Loss

• Trade goes wrong
• Stop triggers at 2% loss
• Move on to next trade
• Account intact

Emotional Protection

Stop losses remove emotions from exit decisions:

• No hoping for recovery
• No praying for miracles
• No denial of reality
• Pre-planned, automatic execution

Professional Standard

Every professional trader uses stop losses. Period. They understand that capital preservation is the foundation of long-term success.

Types of Stop Loss Orders

Fixed Stop Loss

A predetermined price level set when entering the trade.

How it works:

• You enter long at 1.1000
• Stop loss at 1.0950 (50 pips)
• If price hits 1.0950, position closes automatically

Advantages:

• Simple and clear
• Easy to calculate risk
• No decision-making after entry
• Protects against catastrophic losses

Disadvantages:

• Fixed location may not respect structure
• May be too tight or too wide
• Doesn't adapt to market conditions

Trailing Stop Loss

A stop that moves with price, locking in profits.

How it works:

• You enter long at 1.1000
• Set trailing stop at 30 pips
• Price moves to 1.1050, stop moves to 1.1020
• Price moves to 1.1100, stop moves to 1.1070
• Stop only moves in profitable direction

Advantages:

• Locks in profits automatically
• Lets winners run
• Removes exit decisions
• Protects against reversals

Disadvantages:

• May exit too early on volatility
• Requires proper distance setting
• Can give back open profits if too tight

Mental Stop Loss

A price level where you'll manually exit.

How it works:

• You watch the trade
• When price hits your stop level, you click to close
• No automatic order in the market

Advantages:

• Flexibility for interpretation
• Can consider context before exiting
• Avoids stop hunting in some situations

Disadvantages:

• Requires constant monitoring
• Emotional interference possible
• Risk of not exiting when you should
• No protection if you're away from computer

Verdict: Use hard stops. Mental stops invite disaster.

Time-Based Stop

Exit if price doesn't move in your favor within a time period.

How it works:

• You enter a trade
• If not profitable within X hours/days, exit
• Regardless of price level

When to use:

• Day trading (close by session end)
• Swing trades that stall
• Momentum trades that lose momentum

Stop Loss Placement Methods

Method 1: Percentage-Based

Risk a fixed percentage of your account per trade.

How to use:

1. Decide on risk percentage (e.g., 1%)
2. Calculate dollar risk ($10,000 × 1% = $100)
3. Place stop based on this amount

Limitation: This determines position size, not stop placement. You still need to decide WHERE to place the stop, then calculate position size accordingly.

Method 2: Structure-Based

Place stops beyond significant support/resistance levels.

For Long Trades:

• Identify key support below entry
• Place stop beyond that support
• Give room for wicks and false breaks

For Short Trades:

• Identify key resistance above entry
• Place stop beyond that resistance
• Account for spikes and overshoots

Example:

• Entry: 1.1000 (at support)
• Key support: 1.0960
• Stop placement: 1.0940 (below support + buffer)

Advantages:

• Respects market structure
• Logical placement
• Trade is invalidated if stop hits

Method 3: ATR-Based

Use Average True Range to set stops based on volatility.

How to use:

1. Calculate ATR (14-period typical)
2. Multiply by factor (1.5 to 3×)
3. Place stop that distance from entry

Example:

• EUR/USD ATR(14) = 50 pips
• Use 2× ATR = 100 pips
• Entry at 1.1000, stop at 1.0900 (long)

Advantages:

• Adapts to market volatility
• Wider stops in volatile markets
• Tighter stops in quiet markets
• Reduces whipsaws

Method 4: Moving Average-Based

Use moving averages as your stop reference.

How to use:

• In uptrends, place stop below a rising MA (e.g., 20 or 50 EMA)
• In downtrends, place stop above a falling MA
• Exit if price closes beyond the MA

Advantages:

• Dynamic and adapts to trends
• Gives you an objective level
• Popular trailing stop method

Disadvantages:

• May be far from entry initially
• Doesn't respect price structure specifically

Method 5: Candlestick-Based

Use recent candlestick patterns to place stops.

Examples:

• For a hammer long entry: Stop below the hammer's low
• For a shooting star short: Stop above the shooting star's high
• Entry bar stop: Stop beyond the entry candle's extreme

Advantages:

• Logical and visible
• Close to entry (tight stops possible)
• Clear invalidation point

Disadvantages:

• May be too tight if entry candle is small
• May be too wide if entry candle is large

Method 6: Fib Level-Based

Use Fibonacci retracement levels for stop placement.

How to use:

• Entry at 61.8% retracement
• Stop below 78.6% retracement
• Or stop below 100% (beyond the swing low)

Advantages:

• Aligns with popular levels
• Logical invalidation point
• Works well with Fibonacci strategies

Common Stop Loss Mistakes

Mistake 1: Placing Stops at Obvious Levels

Problem:

• Stop at round numbers (1.1000)
• Stop at exact support levels
• Stop at obvious swing lows/highs

These levels attract stop hunters. Price sweeps through, triggers stops, then reverses.

Solution: Add a buffer beyond the obvious level. If support is at 1.0950, consider stop at 1.0930.

Mistake 2: Stops Too Tight

Problem:

• Stops within normal ranging movement
• Getting stopped out repeatedly before the move happens
• High win consistency but many unnecessary losses

Solution:

• Use ATR to understand normal volatility
• Give trades room to breathe
• Accept that wider stops require smaller position sizes

Mistake 3: Stops Too Wide

Problem:

• Stops so far away that risk is excessive
• Large losses when stops trigger
• Poor risk-to-reward ratios

Solution:

• Define maximum acceptable risk first
• If required stop is too far, reduce position size or skip trade
• Maintain consistent risk per trade

Mistake 4: Moving Stops Further Away

Problem:

• Trade goes against you
• You move stop to avoid taking loss
• Loss grows larger when finally stopped

Solution: Never move a stop further away. The stop was set for a reason. If hit, accept the loss.

Mistake 5: No Stop Loss At All

Problem:

• Trusting hope over planning
• Small losses becoming account destroyers
• No risk control

Solution: Always use a stop loss. No exceptions. Ever.

Trailing Stop Techniques

Technique 1: Fixed Pip Trail

Set the trail at a fixed pip distance.

Example:

• Trailing stop at 30 pips
• Price moves up, stop follows up 30 pips behind
• Never moves backward

Best for: Trending markets with steady moves.

Technique 2: ATR-Based Trail

Trail stop based on current volatility.

How it works:

• Set trail at 2× ATR
• As volatility changes, trail distance adapts
• Wider in volatile markets, tighter in quiet markets

Best for: Variable market conditions.

Technique 3: Moving Average Trail

Use a moving average as your trailing stop.

How it works:

• Long trade: Trail stop below the rising 20 EMA
• Exit when price closes below the MA
• Short trade: Trail stop above the falling 20 EMA

Best for: Trend-following strategies.

Technique 4: Swing Point Trail

Move stop to below/above previous swing points.

How it works:

• Long trade: Move stop to below each new higher low
• Protect profits as higher lows form
• Short trade: Move stop to above each new lower high

Best for: Swing trading strategies.

Technique 5: Time-Based Progression

Tighten stops as time passes.

How it works:

• Day 1: 2× ATR stop
• Day 3: 1.5× ATR stop
• Day 5: 1× ATR stop

Reasoning: If the trade was correct, price should have moved. Tighten stop to force the trade to work or get out.

Break-Even Stops

What Is a Break-Even Stop?

Moving your stop to your entry price after the trade moves in your favor. If the trade reverses, you exit at no loss.

When to Use

Common rule: Move to break-even after achieving 1:1 profit/risk distance.

Example:

• Entry: 1.1000
• Stop: 1.0960 (40 pips risk)
• Price reaches 1.1040 (40 pips profit)
• Move stop to 1.1000 (break-even)

The Trade-Off

Advantages:

• Eliminates risk on the trade
• Psychological relief
• Protects against reversal

Disadvantages:

• May get stopped at break-even on a winning trade
• Reduces overall expectancy for some strategies
• Can be stopped out on normal pullbacks

Consideration: Move to break-even + a few pips (e.g., break-even +5) to cover spread and commissions.

Practical Tips

Tip 1: Know Your Stop Before Entry

Before clicking buy or sell:

• Know exactly where your stop goes
• Calculate your risk
• Determine position size based on stop distance

Tip 2: Set the Stop Immediately

Don't enter a trade "to set the stop later." Set it as part of the entry order or immediately after.

Tip 3: Accept the Risk

If you can't accept losing the amount at risk, either:

• Trade smaller
• Widen the stop and reduce position size
• Skip the trade

Tip 4: Review Stopped Trades

After each stop:

• Was the stop in the right place?
• Did price reverse immediately after (stop hunt)?
• Was the trade thesis wrong, or just unlucky?

Use data to refine your stop placement.

Tip 5: Consider the Spread

Account for spread in stop placement, especially on pairs with wider spreads. Your actual price may differ from the chart.

Conclusion

Stop losses are the foundation of risk management. Without them, even the best trading strategy will eventually destroy your account. With proper stops, you can survive losing streaks and stay in the game long enough for your edge to play out.

Key takeaways:

• Always use a stop loss—no exceptions
• Place stops at logical levels, beyond key structure
• Add buffers to avoid obvious stop-hunting zones
• Consider using ATR for volatility-adjusted stops
• Never move a stop further away

Master stop loss placement, and you master the most important aspect of trading risk management. Your stops won't make you profitable, but they will keep you in the game. And staying in the game is the prerequisite for everything else.

Make stop losses your best friend. They're not there to hurt you—they're there to protect you.
