Stop-Loss Placement: Where and Why
Your stop goes where your trade idea is wrong. Not where you're comfortable losing.
Researched and written by Laurent The Golden Rule of Stop Placement
Your stop-loss goes at the price where your trade idea is no longer valid. If you bought because price bounced off support at 1.0800, your stop goes below that support, say at 1.0780. If price trades below 1.0780, the support has broken and your reason for being in the trade no longer exists.
Method 1: Structural Stop (S/R Based)
Place the stop just beyond the nearest significant support (for longs) or resistance (for shorts):
- Long trade: Stop a few pips below the support level or swing low that defines your setup.
- Short trade: Stop a few pips above the resistance level or swing high.
- "A few pips": 5-10 pips beyond the level for majors. This gives room for wicks that test the level without actually breaking it.
Method 2: ATR-Based Stop
Use the Average True Range to set a stop that accounts for normal market volatility:
- Calculate ATR for the current timeframe (typically 14-period)
- Place stop at 1.5x ATR from entry
- This adapts automatically: wider stops in volatile markets, tighter in calm markets
H4 ATR on EUR/USD = 35 pips
1.5x ATR = 52 pips
You buy at 1.0850. Stop at 1.0850 - 0.0052 = 1.0798
Method 3: Candle-Based Stop
Place the stop below/above the signal candle that triggered your entry:
- Bullish engulfing at support: Stop below the low of the engulfing candle.
- Bearish pin bar at resistance: Stop above the high of the pin bar.
This is the tightest stop method, giving the best RR, but also the most likely to get hit by normal price noise.
The Wrong Way to Set a Stop
Never set a stop based on how much money you're willing to lose. "I'll put my stop 15 pips away because that's $150 on 1 lot" is backwards. If the support level is 40 pips below your entry, a 15-pip stop will get hit by normal market noise, turning a valid trade idea into a loss.
Instead: place the stop where it belongs (40 pips below), then calculate lot size so that 40-pip loss equals your risk amount ($150). The formula from Lesson 7-3 handles this automatically.
1. Find the technical level where your idea is invalid
2. Add a small buffer (5-10 pips or wicks)
3. That's your stop distance
4. Calculate lot size: risk $ / (stop pips x pip value)
5. If the lot size is too small to be meaningful, skip the trade
Key Takeaways
- • Place stops where your trade idea is INVALIDATED, not based on a dollar amount.
- • Method 1: Below/above the nearest S/R level (structural stop).
- • Method 2: 1.5x ATR from entry (volatility-based stop).
- • Then calculate lot size to fit the stop within your risk %. Never the other way around.
