Most traders use a stop loss.
Few traders place it correctly.
A stop loss is often treated as a number of pips chosen arbitrarily—10 pips, 20 pips, or “just below the last candle.” This approach creates a dangerous illusion of risk control while ignoring how markets actually move.
In this article, you will learn how to place stop losses logically, based on structure and volatility, and why improper stop placement is one of the main reasons traders with decent strategies still lose money.

Risk Management #2: Position Sizing Explained
Because without correct stop placement, position sizing cannot function properly.
What a Stop Loss Is (and What It Is Not)
A stop loss is not:
-
A random pip distance
-
A pain tolerance threshold
-
A place to “hope the market doesn’t reach”
A stop loss is:
-
A point where your trade idea is proven wrong
-
A structural invalidation level
-
A predefined exit for capital protection
Professionals place stops where the market logic breaks, not where losses feel uncomfortable.
Stop Loss Placement Must Be Logical, Not Emotional
The market does not know where you entered.
It only responds to:
-
Structure
-
Liquidity
-
Volatility
When a stop is placed emotionally:
-
It is usually too tight
-
It sits near obvious levels
-
It gets triggered during normal price noise
When placed logically:
-
It aligns with structure
-
It allows normal fluctuation
-
It invalidates the trade idea decisively
Structure-Based Stop Loss Placement
Using Market Structure
Structure-based stops rely on:
-
Swing highs and lows
-
Support and resistance zones
-
Breaks of structure (BOS)
Example:
-
In an uptrend, a long trade is invalidated only if price breaks below the most recent higher low
-
A stop placed above that level lacks structural meaning
This approach filters out noise and ensures that stops represent idea failure, not random volatility.
Structure is introduced in the Foundation/Core Concepts silo and becomes practical here.
Volatility-Based Stop Loss Placement
Structure alone is not enough.
Markets expand and contract.
Stops must adapt.
Volatility-based placement uses:
-
Average True Range (ATR)
-
Recent candle ranges
-
Session-based volatility
In high volatility conditions:
-
Stops must be wider
-
Position size must be reduced
In low volatility conditions:
-
Stops can be tighter
-
Position size can increase safely

Ignoring volatility is a common cause of repeated stop-outs during news or session opens.
The Stop Loss–Position Size Connection
A stop loss does not control risk by itself.
Risk is controlled by:
Stop loss distance × position size
A tighter stop does not reduce risk unless position size is adjusted accordingly.
This is why traders who tighten stops without recalculating position size often experience:
-
Frequent stop-outs
-
Inconsistent losses
-
Psychological frustration

Common Stop Loss Mistakes That Kill Accounts
1. Placing Stops at Obvious Levels
Retail stops cluster around:
-
Round numbers
-
Exact highs/lows
-
Obvious support/resistance
These areas attract liquidity.
The market often trades through these levels before moving in the intended direction.
2. Using the Same Stop Distance for Every Trade
Markets change.
Volatility changes.
A fixed 15-pip stop across all conditions guarantees inconsistent results.
3. Moving Stops Emotionally
Common behaviors:
-
Moving stops further “to give the trade room”
-
Removing stops entirely
-
Tightening stops prematurely to avoid loss
These actions destroy the integrity of the risk plan and turn trading into gambling.
Stop Loss Placement and Losing Streaks
Poor stop placement amplifies losing streaks.
When stops are:
-
Too tight → frequent small losses accumulate rapidly
-
Too wide without sizing adjustment → large losses accelerate drawdowns
Correct stop logic:
-
Smooths equity curves
-
Keeps losses proportional
-
Improves psychological resilience

Stop Losses Protect Capital, Not Ego
A stopped-out trade does not mean you were wrong as a trader.
It means the market invalidated a specific idea.
Professionals accept stops as operational costs, not personal failures.
When stop loss logic is respected:
-
Risk remains consistent
-
Confidence remains intact
-
Long-term performance improves

Final Thoughts
Stop losses are not optional.
They are not negotiable.
They are the boundary between controlled trading and financial chaos.
Placed logically, a stop loss becomes a professional tool—not a source of fear.
