Risk Management & Position Sizing Cheatsheet
Risk Management & Exits
How to define stops, size positions, take profits, and survive catastrophic losses. The difference between trading and gambling.
🛡️ THE 3 NON-NEGOTIABLE RULES
Before every single trade, you must:
- 1.Define your stop loss price (where you're wrong)
- 2.Calculate your position size (so a loss = 1% of account, not 10%)
- 3.Confirm portfolio heat is under 5% (total risk across all open trades)
Break any of these and you're gambling, not trading.
📐 COMPLETE TRADE EXAMPLE
Account: $10,000 | Risk per trade: 1% ($100) | Asset: BTC
Step 1 — Define Stop
BTC at $45,000, support at $42,750. Stop = $42,750 (5% below entry)
Step 2 — Position Size
Risk $100 / Stop distance 5% = $2,000 position (0.044 BTC)
Step 3 — Take Profit
2:1 R:R → Target = $49,500 (10% above entry)
Step 4 — Portfolio Heat
This trade risks 1%. Other open trades risk 2.5%. Total heat = 3.5% ✓
Step 5 — Execute
Set limit buy at $45,000, stop-loss at $42,750, take-profit at $49,500
If Stopped Out
You lose $100 (1% of account). You can take 10 more consecutive losses before losing 10%.
If Target Hit
You gain $200 (2% of account). You only needed to win 33% of trades to break even.
The Golden Rule
You must know your stop loss before you enter. If you can't define a logical stop, the setup isn't tradeable. Most traders lose because they define their stop AFTER they're emotionally attached to being right.
Risk management isn't about maximizing wins — it's about staying in the game long enough to accumulate edge. Blow up your account on one bad trade, and years of work are gone. Protect capital first. Profits are a byproduct.
Four Stop-Loss Placement Methods
Each has strengths. Learn all four. Use the one that makes sense for your setup.
ATR-Based Stop Loss
Entry ± (ATR × Multiplier)
Example
Entry: $50, ATR(14): $2, Multiplier: 2 → Stop: $46 (shorts $54)
Rules
- •14-period ATR is standard; adjust for volatility regime
- •Multiplier 1.5–3× depending on timeframe (lower = tighter, higher = looser)
- •Works best on momentum entries; adapts to changing volatility
- •Avoid ATR stops at key support/resistance — they may snap you out
Best For
Momentum breakouts · Intraday swings · High-volatility pairs
Support/Resistance Stop Loss
Below nearest swing low (shorts: above swing high)
Example
Buying at $50 with prior swing low at $46.50 → Stop: $46.25
Rules
- •Most logical stop placement: price breaks this level = setup failed
- •Often coincides with supply/demand imbalance
- •Ideal for pattern trades (Head & Shoulders, triangles, etc.)
- •Risk is clear: if price breaks here, the bias is wrong
Best For
Pattern trades · Reversal entries · Technical level breaks
Percentage Stop Loss
Entry × (1 ± Risk%)
Example
Entry: $100, Risk 3% → Stop: $97 (shorts: $103)
Rules
- •Simplest method; works on any timeframe
- •Typical ranges: 2–5% for swing trades, 0.5–2% for day trades
- •Ignores volatility — use with caution in high-IV environments
- •Best paired with position size adjustment for risk parity
Best For
Index/stock trading · Consistent risk per trade · Simple setups
Volatility-Adjusted Stop Loss
Entry ± (20-Day Historical Vol × 2)
Example
20-day HV: 8%, Entry: $100 → Stop: $84–$116 (±16%)
Rules
- •Accounts for regime changes (quiet vs. volatile periods)
- •Widen stops in high-volatility regimes (avoid whipsaws)
- •Tighten stops when vol is low (higher probability entries)
- •Use Bollinger Bands or Keltner Channels as visual reference
Best For
Crypto/binary outcomes · Earnings/event trades · Regime-adaptive
Four Profit-Taking Strategies
The exit is more important than the entry. A perfect entry with a bad exit = breakeven or loss.
Fixed R:R Targets
Risk $100 → Target $200 (2:1 R:R)
- ▸Exit entire position when 2:1 R:R is reached
- ▸Guarantees positive expectancy even at 50% win rate
- ▸Simple, mechanical, removes emotion
- ▸Downside: leaves money on the table in extended trends
Scaling Out (1/3 / 2/3 / 3/3)
Sell 1/3 at 1:1 R:R, 1/3 at 2:1 R:R, trail stop on final 1/3
- ▸Lock in profit early while letting winners run
- ▸Psychologically easier: you've already won on 2/3
- ▸Final 1/3 on trailing stop captures mega-moves
- ▸Ideal for breakout trades and momentum setups
Trailing Stop (X% or X points)
Up 15%, then set trailing stop at 5% below peak
- ▸Lets profit run; exits on first serious pullback
- ▸Best for strong trends; avoid choppy consolidations
- ▸Use 2–5% trail on 4h+, 1–3% on intraday
- ▸Can be gamed by market makers — pair with levels
Target Then Trail (Two-Phase Exit)
Sell at 1.5:1 R:R, trail remaining 50% at 3% below peak
- ▸Best of both worlds: capture core profit, then trend-follow
- ▸Removes early exit regret while protecting upside
- ▸Requires monitoring post-target
- ▸Works on any timeframe
Position Sizing Formulas
Position size is the primary lever for managing risk. Stop loss tells you how much you lose; position size tells you HOW MUCH.
Fixed Risk Dollar Amount
#FF3B3BPosition Size = Risk $ / (Entry − Stop)
Example: Risk $100, Entry $50, Stop $48 → Position: $5,000 (100 shares)
- ✓Simple and professional; keeps risk consistent
- ✓Ideal for accounts under $50k
- ✓Risk any trade is identical; win/loss size scales with R:R
Percentage of Account
#FF3B3BRisk% = Account Size × 1–2% / (Entry − Stop)
Example: $100k account, risk 1.5%, Entry $50, Stop $48 → Risk $1,500
- ✓Account grows/shrinks with position size
- ✓Matches institutional money management
- ✓Prevents overleveraging as account grows
- ✓Standard: never risk >1–2% per trade, max 5–6% portfolio heat
Conviction-Scaled Sizing (InDecision Method)
#00D4FFBase Size × Conviction Factor (InDecision score 1–10)
Example: Base position 1% risk; if score 9/10 → 1.5% risk; if score 4/10 → 0.5% risk
- ✓Scale size proportional to setup quality
- ✓High-conviction (9–10): 1.25–1.5× base
- ✓Medium (5–8): 1.0× base
- ✓Low (1–4): 0.25–0.5× base
- ✓Maximizes expected value over time
Kelly Criterion (Advanced)
#8B5CF6Optimal % = (Win% × Avg Win − Loss% × Avg Loss) / Avg Win
Example: 60% wins, 1.5:1 R:R → Optimal risk: 2.4% per trade
- ✓Theoretical maximum growth rate
- ✓Requires 30+ trade history for accuracy
- ✓Often too aggressive; use 50% of Kelly for safety
- ✓Recalculate quarterly as stats change

Portfolio Heat Rules (Total Risk %)
The sum of all open position risks must never exceed your portfolio heat limit. This is the circuit breaker that prevents ruin.
Safe Zone
0–3%All setups acceptable. Take full positions.
Caution Zone
3–5%Raise bar for entry quality. Reduce conviction scaling.
Red Zone
5–7%Only highest-conviction trades. Size down 50%. Tighten stops.
Lockdown
7%+STOP TRADING. Close weakest position or wait for win. Protect capital.
How to Calculate Portfolio Heat
Total Risk = (Trade 1 Risk) + (Trade 2 Risk) + (Trade 3 Risk). Example: 3 trades risking 1.5%, 1%, and 0.5% = 3% total heat (Safe Zone).
Five Cognitive Traps That Kill Accounts
Even with perfect rules, emotion overrides logic. Recognize these patterns before they cost you.
Revenge Trading (after a loss)
Symptom
You lost 2%, now risking 5% on the next trade to 'get even'
Fix
Set daily loss limit (e.g., 3% = walk away). Sleep on it. Risk resets tomorrow.
Stop-Loss Paranoia (moving stops too tight)
Symptom
You enter, then immediately move stop to breakeven, then get stopped out for a small loss
Fix
Define stop BEFORE entry. Write it down. Don't touch it unless new information emerges.
Profit-Taking Too Early (cutting winners short)
Symptom
You exit at 1:1 R:R, then watch it go 3:1 R:R while you're on the sidelines
Fix
Use scaling or trailing stops. Allow at least 2:1 R:R before taking core profit.
Averaging Down (doubling down on losers)
Symptom
You're down 2%, add another 1% position, now down 3%, add more...
Fix
Never add to a losing position without a PLAN. In most cases, just cut it.
Ignoring Portfolio Heat (too many open positions)
Symptom
3 concurrent trades risking 2% each = 6% portfolio heat, then one stop-loss ruins you
Fix
Track total portfolio risk in real-time. Hard cap at 5%. Close weakest trade if over.
