Trailing Stop Guide

📋 Overview

Trailing Stop is a dynamic stop loss that automatically follows price movement in your favor. Instead of fixed SL, it "trails" behind price at a specified distance, locking in profits as the trade moves favorably while giving room for continued profit.

Key Benefits:

  • ✅ Lock in profits automatically

  • ✅ Let winning trades run

  • ✅ No manual intervention needed

  • ✅ Protect against sudden reversals

How It Works:

1. Price moves in your favor
2. SL follows at fixed distance
3. If price reverses, SL remains (profit locked)
4. Order closes when price hits trailing SL

⚙️ Core Settings

1. EnableTrailingStop

EnableTrailingStop = true | false

Controls whether trailing stop is active for all orders.

false (Default - Fixed SL)

Behavior: Stop Loss stays at original level (standard trading).

Example:

Order: EURUSD BUY @ 1.0850
SL: 1.0800 (50 pips)
TP: 1.0950 (100 pips)

Price moves to 1.0920 (+70 pips profit)
→ SL remains at 1.0800 (original)
→ Risk: Still -50 pips if reversal

true (Trailing Stop Active)

Behavior: SL automatically follows price movement.

Example:

Order: EURUSD BUY @ 1.0850
Initial SL: 1.0800
Trailing Distance: 30 pips

Price Movement:
1. Entry: 1.0850, SL: 1.0800 (50 pips below)
2. Price → 1.0880: SL → 1.0850 (30 pips trail distance)
3. Price → 1.0910: SL → 1.0880 (follows)
4. Price → 1.0940: SL → 1.0910 (follows)
5. Price reverses to 1.0910: Order closes at SL 1.0910
   → Profit: 60 pips locked!

Without Trailing: Would still have SL at 1.0800
With Trailing: Locked 60 pips profit ✅

🎯 Configuration Settings

2. TrailingStop_Pips

TrailingStop_Pips = 30  // Distance in pips to trail behind price

Defines how far SL trails behind current price.

Small Distance (10-20 pips) - Tight Trailing

TrailingStop_Pips = 15

Behavior: SL very close to price.

Pros:

  • ✅ Lock profits quickly

  • ✅ Minimize drawdown

  • ✅ Good for scalping

Cons:

  • ❌ Frequent stops due to normal volatility

  • ❌ May exit too early on runners

  • ❌ Requires calm markets

Best for:

  • Scalping strategies (M1-M15)

  • Low volatility pairs (EURUSD, USDCHF)

  • Quick profit taking

Example:

EURUSD Scalping:
Entry: 1.0850
Trailing: 15 pips
TP: 1.0900 (50 pips)

Price → 1.0880: SL → 1.0865 (locked 15 pips)
Price → 1.0890: SL → 1.0875 (locked 25 pips)
Price reverses to 1.0875: Closed with 25 pips ✅

Medium Distance (30-50 pips) - Balanced Trailing

TrailingStop_Pips = 40

Behavior: Moderate distance, balance between protection and room.

Pros:

  • ✅ Good profit protection

  • ✅ Room for normal pullbacks

  • ✅ Versatile for most pairs

Cons:

  • ❌ May give back some profit

  • ❌ Requires monitoring

Best for:

  • Day trading (H1-H4)

  • Standard forex pairs

  • Balanced risk/reward

Example:

GBPUSD Day Trade:
Entry: 1.2700
Trailing: 40 pips
TP: 1.2850 (150 pips)

Price → 1.2800 (+100 pips): SL → 1.2760 (locked 60 pips)
Price → 1.2850 (TP hit): SL never triggered, full profit

Large Distance (60-100+ pips) - Wide Trailing

TrailingStop_Pips = 80

Behavior: SL far behind, maximum room for runners.

Pros:

  • ✅ Let big trends develop

  • ✅ Avoid premature exits

  • ✅ Handle volatility well

Cons:

  • ❌ Give back significant profit on reversals

  • ❌ Requires strong trends

Best for:

  • Swing trading (H4-Daily)

  • Volatile pairs (GBPJPY, XAUUSD)

  • Trend following strategies

Example:

XAUUSD Swing Trade:
Entry: 2650
Trailing: 80 points ($8/lot)
TP: 2800 (150 points)

Price → 2750 (+100 points): SL → 2670 (locked 20 points)
Price → 2800 (TP): SL → 2720 (locked 70 points, but TP hit first)

3. TrailingStop_Step

TrailingStop_Step = 5  // Minimum price movement to trigger SL adjustment

Controls how often SL updates (prevents excessive modifications).

Purpose:

  • Reduce broker requests (avoid "too frequent modifications" errors)

  • Smooth trailing (not every tick)

  • Optimize performance

Small Step (1-5 pips) - Frequent Updates

TrailingStop_Step = 1

Behavior: SL updates almost every favorable price movement.

Pros:

  • ✅ Maximizes locked profit

  • ✅ Precise trailing

Cons:

  • ❌ Many broker requests

  • ❌ May hit modification limits

  • ❌ Increased execution load

Best for:

  • Brokers with no modification limits

  • Scalping with tight trailing

  • High precision strategies

Medium Step (5-10 pips) - Balanced Updates

TrailingStop_Step = 5

Behavior: SL updates every 5 pip movement in your favor.

Pros:

  • ✅ Good profit locking

  • ✅ Reasonable broker requests

  • ✅ Works with most brokers

Cons:

  • ❌ May miss 1-4 pips of potential lock

Best for:

  • Most trading styles

  • Standard brokers

  • Recommended default

Example:

EURUSD BUY @ 1.0850
Trailing: 30 pips, Step: 5 pips

Price: 1.0850 → 1.0854: No update (< 5 pips)
Price: 1.0850 → 1.0856: Update! SL → 1.0826
Price: 1.0856 → 1.0860: No update (< 5 pips)
Price: 1.0856 → 1.0861: Update! SL → 1.0831

Large Step (10-20 pips) - Infrequent Updates

TrailingStop_Step = 15

Behavior: SL updates only on significant price moves.

Pros:

  • ✅ Minimal broker requests

  • ✅ Works with restrictive brokers

  • ✅ Smooth operation

Cons:

  • ❌ Less precise profit locking

  • ❌ May miss optimal SL placement

Best for:

  • Swing trading (large moves anyway)

  • Brokers with modification limits

  • Wide trailing strategies

4. TrailingStart_Pips

TrailingStart_Pips = 20  // Profit in pips before trailing activates

Controls when trailing stop starts (activation threshold).

Zero or Low Start (0-10 pips) - Immediate Trailing

TrailingStart_Pips = 0

Behavior: Trailing starts immediately at entry.

Example:

Entry: 1.0850
Trailing: 30 pips, Start: 0

Price → 1.0851 (+1 pip):
→ Trailing activates immediately
→ SL starts following

Pros:

  • ✅ Maximum protection from start

  • ✅ Lock any profit quickly

Cons:

  • ❌ Frequent stops on small moves

  • ❌ May exit before trade develops

Best for:

  • Very tight scalping

  • Markets with instant movement

  • Maximum protection priority

Medium Start (20-40 pips) - Delayed Activation

TrailingStart_Pips = 30

Behavior: Trailing starts only after reaching profit threshold.

Example:

Order: GBPUSD BUY @ 1.2700
SL: 1.2650 (50 pips)
Trailing: 40 pips
Start: 30 pips

Timeline:
1. Entry: 1.2700, SL: 1.2650 (fixed)
2. Price → 1.2720 (+20 pips): SL stays at 1.2650 (below activation)
3. Price → 1.2730 (+30 pips): ✅ Trailing activates!
   → SL → 1.2690 (40 pips trail distance)
4. Price → 1.2760: SL → 1.2720 (follows)
5. Price reverses to 1.2720: Closed with +20 pips locked

Pros:

  • ✅ Trade has room to breathe initially

  • ✅ Avoids premature trailing in choppy entry

  • ✅ Professional approach

Cons:

  • ❌ Original SL risk until activation

Best for:

  • Day trading (H1-H4)

  • Most strategies (recommended)

  • Balanced approach

High Start (50-100+ pips) - Late Activation

TrailingStart_Pips = 80

Behavior: Trailing only starts after significant profit.

Example:

XAUUSD BUY @ 2650
SL: 2620 (30 points)
Trailing: 50 points
Start: 80 points

Price → 2730 (+80 points): ✅ Trailing activates
→ SL: 2620 → 2680 (locked 30 points profit)

Pros:

  • ✅ Maximum room for trend development

  • ✅ Avoid noise in consolidation

  • ✅ Only trail confirmed runners

Cons:

  • ❌ Large risk until activation

  • ❌ May never activate on small moves

Best for:

  • Swing trading (H4-Weekly)

  • Strong trend following

  • Runner strategies

💼 Real-World Examples

Example 1: Scalping EURUSD (Tight Trailing)

Configuration:

EnableTrailingStop = true
TrailingStop_Pips = 15
TrailingStop_Step = 5
TrailingStart_Pips = 10

Trade:

Entry: EURUSD BUY @ 1.0850
Initial SL: 1.0830 (20 pips)
TP: 1.0890 (40 pips)

Timeline:
1. Entry: 1.0850, SL: 1.0830

   → SL → 1.0845 (15 pips trail)
3. Price → 1.0870: SL → 1.0855
4. Price → 1.0880: SL → 1.0865
5. Price reverses to 1.0865: Closed
   → Profit: 15 pips (instead of -5 without trailing)

Example 2: Day Trading GBPUSD (Balanced Trailing)

Configuration:

EnableTrailingStop = true
TrailingStop_Pips = 40
TrailingStop_Step = 10
TrailingStart_Pips = 30

Trade:

Entry: GBPUSD SELL @ 1.2800
Initial SL: 1.2850 (50 pips)
TP: 1.2650 (150 pips)

Timeline:
1. Entry: 1.2800, SL: 1.2850 (fixed)
2. Price → 1.2770 (+30 pips): Trailing activates
   → SL: 1.2850 → 1.2810 (40 pips trail)
3. Price → 1.2720: SL → 1.2760 (locked 40 pips)
4. Price → 1.2680: SL → 1.2720 (locked 80 pips)
5. Price reverses to 1.2720: Closed
   → Profit: 80 pips ✅ (instead of losing all)

Example 3: Swing Trading XAUUSD (Wide Trailing)

Configuration:

EnableTrailingStop = true
TrailingStop_Pips = 100
TrailingStop_Step = 20
TrailingStart_Pips = 100

Trade:

Entry: XAUUSD BUY @ 2650
Initial SL: 2600 (50 points)
TP: 2850 (200 points)

Timeline:
1. Entry: 2650, SL: 2600 (fixed)
2. Price → 2750 (+100 points): Trailing activates
   → SL: 2600 → 2650 (100 points trail, breakeven!)
3. Price → 2820: SL → 2720 (locked 70 points)
4. Price → 2850 (TP): Full profit taken
   → Trailing never triggered, hit TP

Example 4: Volatile Pair GBPJPY (Adaptive)

Configuration:

EnableTrailingStop = true
TrailingStop_Pips = 60
TrailingStop_Step = 10
TrailingStart_Pips = 50

Reasoning: GBPJPY moves fast, needs room but also protection.

Trade:

Entry: GBPJPY BUY @ 188.50
Initial SL: 187.80 (70 pips)
TP: 190.00 (150 pips)

Timeline:
1. Entry: 188.50, SL: 187.80
2. Price spikes to 189.20, pulls back to 189.00
   → SL: 187.80 → 188.40 (locked 60 pips trail)
3. Price rallies to 189.80
   → SL → 189.20 (locked 70 pips)
4. Price hits 190.00: TP taken

⚠️ Common Mistakes

❌ Mistake 1: Too Tight Trailing

Bad:

Symbol: GBPUSD (volatile)
TrailingStop_Pips = 10  // Too tight!

Result: Stopped out constantly by normal volatility.

Good:

TrailingStop_Pips = 40-50  // Match pair volatility

❌ Mistake 2: No Activation Delay

Bad:

TrailingStart_Pips = 0
TrailingStop_Pips = 20
// Trails immediately, stops on entry noise

Good:

TrailingStart_Pips = 30
TrailingStop_Pips = 20
// Let trade develop first

❌ Mistake 3: Step Too Small

Bad:

TrailingStop_Step = 1  // Updates every pip!
// Result: "Too frequent modifications" broker error

Good:

TrailingStop_Step = 5-10

❌ Mistake 4: Same Settings for All Pairs

Bad:

EURUSD (low vol): TrailingStop_Pips = 50 (too wide)
XAUUSD (high vol): TrailingStop_Pips = 50 (too tight)

Good: Use separate EA instances or ATR-based trailing.

❌ Mistake 5: Trailing Wider Than Initial SL

Bad:

Initial SL: 30 pips
TrailingStop_Pips = 50  // Wider than initial!
// Result: SL moves away from entry (increases risk)

Good:

Trailing should be ≤ Initial SL distance

✅ Best Practices

✅ 1. Match Trailing to Timeframe

Timeframe
Trailing Distance
Start Threshold

M1-M5 (Scalp)

10-20 pips

5-10 pips

M15-H1 (Day)

30-50 pips

20-40 pips

H4 (Swing)

60-100 pips

50-80 pips

Daily+ (Position)

100-200 pips

100-150 pips

✅ 2. Match Trailing to Pair Volatility

Low Volatility (EURUSD, USDCHF):

TrailingStop_Pips = 25-35

Medium Volatility (GBPUSD, AUDUSD):

TrailingStop_Pips = 40-60

High Volatility (GBPJPY, XAUUSD):

TrailingStop_Pips = 70-120

✅ 3. Use Activation Threshold

Recommended:

TrailingStart_Pips = 1.0-1.5x TrailingStop_Pips

Example:
TrailingStop_Pips = 40
TrailingStart_Pips = 50-60

Benefit: Trade has room to develop before trailing starts.

✅ 4. Set Step Appropriately

TrailingStop_Step = 10-20% of TrailingStop_Pips

Example:
TrailingStop_Pips = 50
TrailingStop_Step = 5-10

✅ 5. Test Before Live

  • Enable on demo for 1-2 weeks

  • Monitor EA logs for SL modifications

  • Verify trailing activates correctly

  • Check profit locking works as expected

🎯 Strategy Combinations

Conservative Trailing (Lock Profits Fast)

EnableTrailingStop = true
TrailingStop_Pips = 25
TrailingStop_Step = 5
TrailingStart_Pips = 20

Result: Quick profit protection, accept frequent exits.

Balanced Trailing (Recommended)

EnableTrailingStop = true
TrailingStop_Pips = 40
TrailingStop_Step = 10
TrailingStart_Pips = 50

Result: Good balance of protection and room to run.

Aggressive Trailing (Let Trends Run)

EnableTrailingStop = true
TrailingStop_Pips = 80
TrailingStop_Step = 15
TrailingStart_Pips = 100

Result: Maximum runner potential, give back more on reversals.

📞 FAQ

Q: Can I use trailing stop with fixed SL at same time? A: Yes. Initial SL is fixed until trailing activates.

Q: Does trailing work with pending orders? A: Yes, trailing starts after order is triggered and reaches activation threshold.

Q: Can I disable trailing for specific symbols? A: Not directly. Use separate EA instances or disable globally.

Q: What if price gaps through trailing SL? A: Order closes at actual price (standard MT4 behavior), may have slippage.

Q: Does trailing affect TP? A: No, TP remains fixed. If TP is hit, trailing SL is irrelevant.

Remember: Trailing stop is a powerful tool to let winners run while protecting profits. Use it wisely! 📈
