Types of Stop Losses
A Stop Loss Is Not Optional
Four stop types · pick one before you enter
A stop loss is an order that automatically closes your trade if the market moves against you by a specified amount. It is the single most important tool for capital preservation. Trading without a stop loss is not trading — it is gambling with unlimited downside.
In October 2014, a retail trader in the UK held a large leveraged position in a small-cap stock without a stop loss. The company issued a profit warning overnight. By the time markets opened the next morning, the stock had gapped down 40%. The trader not only lost his entire account — he owed his broker an additional $65,000 due to negative balance. A stop loss would not have prevented the gap, but proper position sizing combined with a stop loss would have limited the damage to a small, predefined percentage of his account.
Definition
Hard Stop Loss
A fixed price level at which your position is automatically closed. Once set, it does not move (unless you trail it). Example: Buy EUR/USD at 1.1050 with a hard stop at 1.1000. This is a server-side order — it executes even if your internet connection drops or your platform crashes.
Definition
Structure Stop Loss
A stop placed just beyond a significant technical level — a swing low, a support zone, or a key pivot. This is the preferred method for most traders because it respects market structure rather than an arbitrary pip count. The logic: if price breaks the structure level, your trade idea is genuinely invalidated.
Definition
ATR Stop Loss
A stop based on the Average True Range (ATR), which measures recent volatility. For example, placing a stop 1.5x ATR from entry ensures you're not stopped out by normal daily volatility. More volatile pairs get wider stops. A pair with a 14-period ATR of 80 pips would get a 120-pip stop (1.5x ATR), while a pair with a 40-pip ATR would get a 60-pip stop.
Definition
Mental Stop Loss
A price level where you intend to exit, but no actual order is placed. This is dangerous for retail traders because it relies on discipline in the moment of loss. Professional traders almost universally use hard stops, not mental stops. The only exception is very experienced scalpers trading with direct market access.
Definition
Time Stop
Exiting a trade if it has not moved in your favor within a specified time period. For example: 'If this trade is not profitable within 4 hours, I exit at market.' Time stops prevent capital from being tied up in stagnant trades that are consuming margin and opportunity cost.
Stop Loss Types Compared
| Stop Type | Placement Method | Advantages | Disadvantages | Best For |
|---|---|---|---|---|
| Hard/Fixed | Set at entry, never moved | Simple, guaranteed exit | Ignores market structure | Complete beginners |
| Structure | Beyond swing high/low | Technically logical | Varies per trade | Most traders (recommended) |
| ATR-Based | 1-2x ATR from entry | Adapts to volatility | Requires ATR calculation | Swing/position traders |
| Mental | Memorized, no order placed | Maximum flexibility | Easily ignored under pressure | Expert scalpers only |
| Time | Exit after X hours if not profitable | Frees capital | May miss delayed moves | Day traders |
| Breakeven | Moved to entry after 1R profit | Eliminates risk | May get stopped before full move | All traders as a trailing tool |
The choice of stop loss type should depend on your trading style and the specific setup. For most retail traders, a structure-based stop loss is the best default — it places the stop at a level that makes technical sense, where the trade idea is genuinely invalidated. The ATR-based stop is an excellent second choice, especially for traders who struggle with the subjectivity of identifying structure levels.
Never trade without a stop loss
In September 2019, a currency flash crash hit USD/JPY during thin Asian session liquidity. USD/JPY dropped 4% in minutes (approximately 400 pips). Traders without stops suffered massive, uncontrolled losses. Even those with stops experienced some slippage — but their losses were manageable. Those without stops lost everything. 'I was going to close it manually if it went against me' is the most expensive sentence in trading.
Where Beginners Put Stops Wrong
The most common mistake is placing a stop at a round psychological number (1.1000, 1.2500) or at a fixed pip count that doesn't reflect market conditions. Smart money knows where amateur stops cluster and often hunts those levels before reversing. This is known as a 'stop hunt' or 'liquidity sweep.'
Institutional traders and market makers can see the order book. They know that massive clusters of stop loss orders sit just below round numbers and obvious support levels. Price often dips briefly through these levels — triggering all the stops — before reversing sharply in the original direction. The retail trader gets stopped out at the worst possible price, watches the market reverse, and feels like the market is 'out to get them.' It is not personal — it is structural liquidity.
A
Bad Stop Placement
- Round numbers (1.1000, 1.2500) — where everyone clusters
- Fixed pip count ignoring volatility (always 30 pips regardless of pair)
- Too tight — gets hit by normal intraday noise
- Placed before deciding on a trade thesis
- Never adjusted as trade progresses
- Based on how much you 'want' to lose, not market structure
B
Good Stop Placement
- Just beyond swing highs/lows (structure)
- ATR-based to account for current volatility
- Wide enough to breathe, precise enough to protect
- Determined first — then position size is calculated
- Trailed to lock in profit as trade moves in your favour
- Based on where the trade idea is technically invalidated
ATR-Based Stop Loss Sizing Guide
| ATR Multiplier | Stop Width | Best For | Tradeoff |
|---|---|---|---|
| 1.0x ATR | Tight | Scalping, low-volatility environments | Higher chance of being stopped by noise |
| 1.5x ATR | Standard | Day trading, swing trading | Good balance of protection and breathing room |
| 2.0x ATR | Wide | Swing/position trading | Larger dollar risk per trade — must reduce lot size |
| 2.5x ATR | Very Wide | Position trading, weekly charts | Requires very small positions to stay within risk % |
| 3.0x ATR | Extreme | Long-term macro trades | Very small position sizes; large capital required |
Notice the critical relationship between stop width and position size: as your stop gets wider, your position size must get smaller to maintain the same risk percentage. A 1.0x ATR stop on EUR/USD might be 50 pips, allowing a 2-mini-lot position. A 2.0x ATR stop on the same pair would be 100 pips, cutting your position to 1 mini lot. The dollar risk is identical in both cases — $100 on a $10,000 account at 1%. The wider stop gives more room but the narrower stop gives more profit per pip if the trade works. This is the fundamental tradeoff of stop loss design.
How to Calculate an ATR-Based Stop Loss
- 1
Step 1 — Find the current ATR value
Apply the 14-period ATR indicator on your trading timeframe. Example: EUR/USD on H4 shows ATR(14) = 42 pips.
- 2
Step 2 — Choose your ATR multiplier
For day trading, use 1.5x ATR. For swing trading, use 2.0x ATR. For this example (H4 day trade): 42 x 1.5 = 63 pips.
- 3
Step 3 — Place the stop
For a long trade, stop = entry price - ATR stop distance. If entry is 1.0850: stop = 1.0850 - 0.0063 = 1.0787.
- 4
Step 4 — Verify against structure
Check that the ATR-calculated stop also makes sense technically. If a key support level sits at 1.0790, your 1.0787 stop is just below it — excellent alignment. If the nearest support is at 1.0820, your ATR stop at 1.0787 may be unnecessarily wide. In this case, consider tightening to just below 1.0820.
- 5
Step 5 — Calculate position size
With a 63-pip stop on a $10,000 account at 1%: $100 / 63 pips = $1.59/pip = 1.59 mini lots. Round down to 1 mini lot.
Entry
1.2650
Stop
1.2590
Target
1.2830
Buy GBP/USD at a key support zone (1.2650). Stop loss is placed 10 pips below the swing low at 1.2590 — far enough to avoid noise but close enough to define risk. Take profit targets the previous resistance at 1.2830, giving a 3:1 risk-reward ratio. On a $10,000 account at 1% risk: $100 / 60 pips = $1.67/pip = 1.67 mini lots. Round down to 1 mini lot.
Define the stop before the position size
Always decide where your stop loss goes before you calculate lot size. The stop location is a technical decision (where is the trade idea invalidated?). The lot size is then a math calculation based on that stop distance and your risk budget. Never reverse this process — never set a lot size first and then squeeze a stop to fit.
Guaranteed stops vs. regular stops
In fast-moving markets, regular stop loss orders can experience slippage — your fill price may be worse than your stop price. Some brokers offer 'guaranteed stop losses' for an extra fee (usually built into a wider spread). For major news events (NFP, ECB rate decisions, elections), a guaranteed stop can be worth the extra cost. During the SNB event in 2015, some regular stops on EUR/CHF experienced hundreds of pips of slippage.
Entry
151.80
Stop
152.60
Target
149.40
Short USD/JPY at resistance (151.80). ATR(14) on H4 = 55 pips. Stop placed at 1.5x ATR = 80 pips above entry at 152.60 — also above the daily swing high at 152.40, providing structural confirmation. Take profit at previous support at 149.40 (240 pips). RR = 1:3. On a $10,000 account at 1%: risk = $100. At USD/JPY 151.80, pip value per standard lot = $6.59. Required pip value = $100 / 80 = $1.25/pip. Position size = $1.25 / $6.59 = 0.19 standard lots. Round down to 0.19 or 1.9 mini lots.
| Scenario | Stop Type | Stop Distance | Lot Size (at 1% of $10k) | Pros | Cons |
|---|---|---|---|---|---|
| GBP/USD day trade | Structure | 45 pips | 0.22 lots | Respects swing low | May need to accept wider stop |
| EUR/USD swing trade | 2x ATR | 90 pips | 0.11 lots | Accounts for volatility | Smaller position size |
| USD/JPY scalp | Fixed 15 pips | 15 pips | 0.67 lots | Tight risk | May hit on normal noise |
| GBP/JPY position trade | 2.5x ATR | 200 pips | 0.05 lots | Very wide room | Tiny position — limited upside per pip |
