Position Sizing Masterclass

The single most important skill in trading. Knowing how much to risk on each trade determines your profitability, drawdown, and longevity.

Stock Position Sizing

Method: Calculate shares based on your risk per trade

Formula: Shares = (Account × Risk%) / (Entry - Stop)

📊 Stock Position Sizer
Risk Amount
$100
Stop Distance
$5
Position Size
20 shares
Position Value: $3000
Risk/Reward Ratio
1:2.0
If target hits: +$300 | If stop hits: -$100
Example: Account $10,000 | Risk 1% ($100) | Entry $150 | Stop $145
→ Stop distance = $5
→ Shares = $100 / $5 = 20 shares
→ Position value = 20 × $150 = $3,000

Forex Position Sizing

Method: Calculate lot size based on pip risk

Note: 1 pip = 0.0001 in most pairs (except JPY = 0.01)

Lot Size (Micro Lots)
20 μ-lots
(= 20000 currency units)
Risk/Reward
1:2.0
If TP hits: +$200 | If Stop hits: -$100
Example: Account $10,000 | Risk 1% ($100) | EUR/USD
→ 1 pip on 1 micro lot = $0.10
→ Stop 50 pips = $5 loss per micro lot
→ Micro lots = $100 / $5 = 20 micro lots

Position Scaling Strategy

The Golden Rule: Scale up slowly after wins. Scale down after losses.

📈 Scaling Timeline
Phase 1: Month 1-2 (Mastery)
Risk $100 per trade
Goal: 50%+ win rate | DO NOT scale yet
Phase 2: Month 3-4 (Confirmation)
Risk $100 per trade
After 100 trades, increase by 20% if profitable
Phase 3: Month 5-6 (Growth)
Risk $120 per trade
Increase by 20% again | Account now: $12000
Phase 4: Month 7-12 (Scaling)
Risk $144 per trade
Compounding 20% every 2 months | Account: $14400
Scaling Rules:
✓ Only scale up 20% at a time (1.2x multiplier)
✓ Wait 2 months between scaling
✓ Scale down to 50% after 2 consecutive losses
✓ Return to normal size after 5 winning trades
Month 1-2
Prove your strategy. 50%+ win rate required. NO SCALING.
Month 3-4
Increase by 20%. Still building confidence.
Month 5+
Scale 20% every 2 months. Compound growth.
