Risk-Reward Ratios - Why 1:3 Isn't Always Better

· 6 min read

Founder, TradeLyser

"Always aim for 1:3 risk-reward"

You've heard this advice everywhere.

But it's wrong.

Let me show you why.

What Is Risk-Reward Ratio?

Definition: The ratio of potential profit to potential loss

Formula: Risk:Reward = Stop Distance : Target Distance

Example:

  • Entry: ₹1,000
  • Stop: ₹980 (₹20 risk)
  • Target: ₹1,060 (₹60 reward)
  • R:R = 1:3

Simple math.


The 1:3 Myth

Why Everyone Loves 1:3

The logic:

  • "I can lose 3 times and still be profitable"
  • "One win covers 3 losses"
  • "It's mathematically sound"

The problem: This ignores win rate.

The Real Math

Scenario A: 1:3 R:R, 30% Win Rate

  • 10 trades: 3 wins, 7 losses
  • Wins: 3 × ₹60 = ₹180
  • Losses: 7 × ₹20 = ₹140
  • Net: +₹40

Scenario B: 1:1 R:R, 60% Win Rate

  • 10 trades: 6 wins, 4 losses
  • Wins: 6 × ₹20 = ₹120
  • Losses: 4 × ₹20 = ₹80
  • Net: +₹40

Same result!

The key: Win rate matters more than R:R


The Complete Picture

What Really Matters

1. Win Rate

  • How often you're right
  • More important than R:R

2. Risk-Reward Ratio

  • How much you win vs lose
  • Important but not everything

3. Trade Frequency

  • How many opportunities you get
  • Affects total returns

4. Position Sizing

  • How much you risk per trade
  • Determines account impact

All four matter together.


Real Examples

Example #1: The High R:R Trader

Setup:

  • R:R: 1:4
  • Win Rate: 25%
  • Trades per month: 8

Monthly Results:

  • 8 trades: 2 wins, 6 losses
  • Wins: 2 × ₹80 = ₹160
  • Losses: 6 × ₹20 = ₹120
  • Net: +₹40

Problem: Very few winning trades

Example #2: The High Win Rate Trader

Setup:

  • R:R: 1:1.5
  • Win Rate: 70%
  • Trades per month: 20

Monthly Results:

  • 20 trades: 14 wins, 6 losses
  • Wins: 14 × ₹30 = ₹420
  • Losses: 6 × ₹20 = ₹120
  • Net: +₹300

Better: More consistent profits

Example #3: The Balanced Trader

Setup:

  • R:R: 1:2
  • Win Rate: 50%
  • Trades per month: 15

Monthly Results:

  • 15 trades: 7.5 wins, 7.5 losses
  • Wins: 7.5 × ₹40 = ₹300
  • Losses: 7.5 × ₹20 = ₹150
  • Net: +₹150

Good: Steady, predictable


The Optimal R:R Formula

The Math

Expected Value = (Win Rate × Avg Win) - (Loss Rate × Avg Loss)

For breakeven: Win Rate × Avg Win = Loss Rate × Avg Loss

Solving for R:R: R:R = Win Rate ÷ Loss Rate

Examples

60% Win Rate:

  • Loss Rate: 40%
  • Optimal R:R: 60% ÷ 40% = 1:1.5

70% Win Rate:

  • Loss Rate: 30%
  • Optimal R:R: 70% ÷ 30% = 1:2.33

50% Win Rate:

  • Loss Rate: 50%
  • Optimal R:R: 50% ÷ 50% = 1:1

40% Win Rate:

  • Loss Rate: 60%
  • Optimal R:R: 40% ÷ 60% = 1:1.5

Why 1:3 Often Fails

Problem #1: Low Win Rate

To make 1:3 work, you need:

  • Win Rate > 25%
  • But most traders can't achieve this consistently

Reality: Most traders have 40-50% win rate

Problem #2: Fewer Opportunities

High R:R setups are rare:

  • Need perfect conditions
  • Wait longer for setups
  • Miss other opportunities

Result: Lower trade frequency

Problem #3: Psychological Pressure

High R:R = High Pressure:

  • "This trade must work"
  • "I can't afford to lose"
  • "I need this win"

Result: Poor execution

Problem #4: Market Reality

Markets don't move in perfect ratios:

  • Targets often not hit
  • Stops often hit
  • Reality ≠ Theory

The Better Approach

Step 1: Find Your Win Rate

Track your last 50 trades:

  • How many won?
  • What's your actual win rate?

Example: 30 wins out of 50 = 60% win rate

Step 2: Calculate Optimal R:R

Formula: R:R = Win Rate ÷ Loss Rate

Example:

  • Win Rate: 60%
  • Loss Rate: 40%
  • Optimal R:R: 60% ÷ 40% = 1:1.5

Step 3: Test Different R:R

Try these scenarios:

Conservative (1:1.2):

  • Lower pressure
  • More opportunities
  • Steady profits

Moderate (1:1.5):

  • Balanced approach
  • Good opportunities
  • Solid profits

Aggressive (1:2):

  • Higher pressure
  • Fewer opportunities
  • Bigger wins

Step 4: Optimize Based on Results

Track for 3 months:

  • Which R:R works best?
  • What's your actual win rate?
  • Adjust accordingly

R:R by Trading Style

Scalping (1:0.8 to 1:1.2)

Characteristics:

  • High win rate (60-70%)
  • Low R:R acceptable
  • High frequency

Example:

  • Win Rate: 65%
  • R:R: 1:1
  • Result: Profitable

Day Trading (1:1.5 to 1:2)

Characteristics:

  • Moderate win rate (50-60%)
  • Moderate R:R
  • Medium frequency

Example:

  • Win Rate: 55%
  • R:R: 1:1.8
  • Result: Profitable

Swing Trading (1:2 to 1:3)

Characteristics:

  • Lower win rate (40-50%)
  • Higher R:R needed
  • Lower frequency

Example:

  • Win Rate: 45%
  • R:R: 1:2.2
  • Result: Profitable

Position Trading (1:3 to 1:5)

Characteristics:

  • Low win rate (30-40%)
  • Very high R:R needed
  • Very low frequency

Example:

  • Win Rate: 35%
  • R:R: 1:3
  • Result: Profitable

The Psychology of R:R

High R:R Problems

1. Perfectionism:

  • "This trade must hit target"
  • "I can't exit early"
  • "I need the full move"

2. Impatience:

  • "When will it move?"
  • "Why is it taking so long?"
  • "I should exit now"

3. Fear:

  • "What if it reverses?"
  • "I can't afford to lose"
  • "This is my only chance"

Lower R:R Benefits

1. Realistic Expectations:

  • "Small wins are fine"
  • "I'll take what I can get"
  • "Consistency matters"

2. Less Pressure:

  • "I don't need perfect trades"
  • "I can exit early if needed"
  • "There are more opportunities"

3. Better Execution:

  • "I'll follow my plan"
  • "I won't force trades"
  • "I'll be patient"

Advanced R:R Concepts

Dynamic R:R

Adjust R:R based on:

Market Conditions:

  • Trending: Higher R:R possible
  • Ranging: Lower R:R needed
  • Volatile: Lower R:R safer

Setup Quality:

  • A+ setup: Higher R:R
  • B setup: Lower R:R
  • C setup: Skip trade

Personal State:

  • Confident: Higher R:R
  • Stressed: Lower R:R
  • Tired: Lower R:R

Partial Exits

Instead of fixed R:R:

Exit 50% at 1:1 Exit 30% at 1:2 Let 20% run

Benefits:

  • Lock in profits
  • Reduce pressure
  • Let winners run

Trailing Stops

Start with 1:1 R:R Move stop to breakeven at +1R Trail stop as price moves

Result: Often achieve 1:2+ R:R


The Bottom Line

Don't chase 1:3 R:R.

Instead:

  1. Find your win rate
  2. Calculate optimal R:R
  3. Test different ratios
  4. Optimize based on results

Remember:

  • Win rate > R:R
  • Consistency > Perfection
  • Profits > Ratios

The best R:R is the one that works for YOU.

How to Calculate Position Size for Options Trading

· 7 min read
Karthik
Founder, TradeLyser

Options trading is different.

Your risk isn't just the premium paid.
It's the premium paid × number of lots.
Plus margin requirements.
Plus assignment risk.

Let me show you how to size options positions correctly.

The Options Risk Challenge

Equity vs Options Risk

Equity trading:

  • Risk: Stop loss distance
  • Simple calculation
  • Clear limits

Options trading:

  • Risk: Premium paid (buying)
  • Risk: Unlimited (selling)
  • Risk: Assignment (short positions)
  • Risk: Time decay
  • Risk: Volatility changes

Much more complex.

Common Options Mistakes

Mistake #1: "I only paid ₹5,000 premium, so I can risk ₹5,000"

Reality: If you buy 10 lots, you risk ₹50,000

Mistake #2: "Selling options is safe, I'll sell many lots"

Reality: One bad move can wipe out months of premiums

Mistake #3: "I'll use all my capital for options"

Reality: Options can go to zero. Equity can't.


Position Sizing for Options Buying

The Basic Formula

For buying options:

Position Size = (Account Risk %) ÷ (Premium Risk %)

Where:
Account Risk % = % of account you want to risk
Premium Risk % = % of premium you expect to lose

Example #1: Buying Call Options

Setup:

  • Account: ₹5,00,000
  • Risk per trade: 2% = ₹10,000
  • NIFTY 24500 CE @ ₹150
  • Expected loss if wrong: 100% (premium)
  • Lot size: 50

Calculation:

Premium Risk % = 100% (total loss)
Position Size = 2% ÷ 100% = 2% of account
Position Value = ₹5,00,000 × 2% = ₹10,000
Number of lots = ₹10,000 ÷ (₹150 × 50) = 1.33 lots
Round down: 1 lot
Investment: 1 × 50 × ₹150 = ₹7,500
Risk: ₹7,500 (1.5% of account)

Example #2: Buying Put Options

Setup:

  • Account: ₹3,00,000
  • Risk per trade: 1.5% = ₹4,500
  • RELIANCE 2500 PE @ ₹80
  • Expected loss: 100%
  • Lot size: 250

Calculation:

Position Size = 1.5% ÷ 100% = 1.5%
Position Value = ₹3,00,000 × 1.5% = ₹4,500
Number of lots = ₹4,500 ÷ (₹80 × 250) = 0.225 lots
Round down: Can't buy fractional lots
Maximum: 0 lots (too expensive)
Alternative: Find cheaper option or increase account

Example #3: Buying Multiple Options

Setup:

  • Account: ₹10,00,000
  • Risk per trade: 2% = ₹20,000
  • Strategy: Buy 1 call + 1 put (straddle)
  • Call: ₹200, Put: ₹180
  • Total premium: ₹380 per lot
  • Expected loss: 100%

Calculation:

Position Size = 2% ÷ 100% = 2%
Position Value = ₹10,00,000 × 2% = ₹20,000
Number of lots = ₹20,000 ÷ ₹380 = 52.6 lots
Round down: 52 lots
Investment: 52 × ₹380 = ₹19,760
Risk: ₹19,760 (1.98% of account)

Position Sizing for Options Selling

The Margin Challenge

Selling options requires margin:

  • SPAN margin
  • Exposure margin
  • Premium received (reduces margin)

Risk: Unlimited (theoretical)

Conservative Approach

Rule: Risk only 1% of account per trade

Example: Selling Call Options

Setup:

  • Account: ₹5,00,000
  • Risk per trade: 1% = ₹5,000
  • NIFTY 25000 CE @ ₹100
  • Margin required: ₹1,20,000 per lot
  • Premium received: ₹5,000 per lot

Calculation:

Maximum margin per trade = ₹5,000
Maximum lots = ₹5,000 ÷ ₹1,20,000 = 0.04 lots
Not possible (minimum 1 lot)

Alternative: Use smaller account portion
Use 0.5% risk = ₹2,500
Still not enough margin

Solution: Use spreads to reduce margin

Using Spreads to Reduce Risk

Bull Put Spread Example:

Setup:

  • Sell NIFTY 24000 PE @ ₹200
  • Buy NIFTY 23900 PE @ ₹150
  • Net premium: ₹50
  • Margin: ₹25,000 per lot
  • Max loss: ₹4,500 per lot

Calculation:

Account: ₹5,00,000
Risk per trade: 1% = ₹5,000
Max loss per lot: ₹4,500
Maximum lots: ₹5,000 ÷ ₹4,500 = 1.1 lots
Round down: 1 lot
Investment: ₹25,000 margin
Risk: ₹4,500 (0.9% of account)

Advanced Position Sizing

Kelly Criterion for Options

Formula:

Kelly % = (Win Rate × Avg Win - Loss Rate × Avg Loss) ÷ Avg Win

Example:
Win Rate: 60%
Avg Win: ₹3,000
Loss Rate: 40%
Avg Loss: ₹2,000

Kelly = (0.6 × 3000 - 0.4 × 2000) ÷ 3000
= (1800 - 800) ÷ 3000
= 0.33 = 33%

Too aggressive for options!

Use Fractional Kelly:

  • Quarter Kelly: 8.25%
  • Half Kelly: 16.5%
  • Recommendation: Quarter Kelly maximum

Volatility-Based Sizing

High VIX (>20):

  • Reduce position size by 50%
  • Options more expensive
  • Higher risk

Low VIX (<15):

  • Normal position size
  • Options cheaper
  • Lower risk

Example:

Normal position size: 2%
High VIX adjustment: 2% × 0.5 = 1%
Low VIX adjustment: 2% (no change)

Options-Specific Risk Factors

Factor #1: Time Decay

Buying options:

  • Time works against you
  • Position size should account for time decay
  • Shorter expiry = smaller position

Selling options:

  • Time works for you
  • Can use larger positions
  • But still limited by margin

Factor #2: Volatility

High volatility:

  • Options expensive
  • Higher risk
  • Smaller positions

Low volatility:

  • Options cheap
  • Lower risk
  • Larger positions possible

Factor #3: Liquidity

High liquidity (NIFTY, Bank NIFTY):

  • Tight spreads
  • Easy to exit
  • Normal position sizes

Low liquidity:

  • Wide spreads
  • Hard to exit
  • Smaller positions

Factor #4: Assignment Risk

Selling options:

  • Risk of early assignment
  • Need to hold underlying
  • Account for assignment cost

Example:

Sell RELIANCE 2500 CE @ ₹50
If assigned: Must buy 250 shares @ ₹2,500
Cost: ₹6,25,000
Account: ₹5,00,000
Problem: Can't afford assignment!

Position Sizing by Strategy

Strategy #1: Long Calls/Puts

Risk: Premium paid
Position size: 1-2% of account
Example: ₹5,00,000 account = ₹5,000-₹10,000 per trade

Strategy #2: Covered Calls

Risk: Underlying stock risk
Position size: Based on stock risk (2% rule)
Example: 100 shares × ₹2,500 = ₹2,50,000 position

Strategy #3: Cash-Secured Puts

Risk: Stock assignment risk
Position size: Based on assignment cost
Example: ₹2,50,000 cash for ₹2,500 strike put

Strategy #4: Spreads

Risk: Spread width
Position size: 1-2% of account
Example: ₹5,000 risk for ₹5,00,000 account

Strategy #5: Iron Condors

Risk: Spread width
Position size: 1% of account
Example: ₹5,000 max loss for ₹5,00,000 account


Real Examples

Example #1: NIFTY Call Buying

Setup:

  • Account: ₹5,00,000
  • NIFTY 24500 CE @ ₹150
  • Expiry: 1 week
  • Risk: 2% = ₹10,000

Calculation:

Premium per lot: ₹150 × 50 = ₹7,500
Maximum lots: ₹10,000 ÷ ₹7,500 = 1.33
Round down: 1 lot
Investment: ₹7,500
Risk: ₹7,500 (1.5% of account)

Result: Good position size

Example #2: RELIANCE Put Selling

Setup:

  • Account: ₹5,00,000
  • RELIANCE 2500 PE @ ₹100
  • Margin: ₹1,50,000 per lot
  • Risk: 1% = ₹5,000

Calculation:

Margin per lot: ₹1,50,000
Maximum lots: ₹5,000 ÷ ₹1,50,000 = 0.033
Not possible (minimum 1 lot)

Problem: Margin too high for account size
Solution: Use spreads or increase account

Example #3: Bank NIFTY Spread

Setup:

  • Account: ₹5,00,000
  • Bull Put Spread
  • Max loss: ₹3,000 per lot
  • Risk: 1% = ₹5,000

Calculation:

Maximum lots: ₹5,000 ÷ ₹3,000 = 1.67
Round down: 1 lot
Investment: ₹15,000 margin
Risk: ₹3,000 (0.6% of account)

Result: Good position size


Common Mistakes

Mistake #1: Using All Capital

Wrong: "I have ₹5L, I'll buy ₹5L worth of options"
Right: Risk only 1-2% per trade

Mistake #2: Ignoring Margin

Wrong: "I'll sell 10 lots, I only need ₹50K"
Right: Check margin requirements first

Mistake #3: No Stop Loss

Wrong: "Options can't lose more than premium"
Right: Set stop loss at 50% premium loss

Mistake #4: Over-Leveraging

Wrong: "I'll buy 20 lots with ₹1L"
Right: Buy 1-2 lots maximum


The Bottom Line

Options position sizing is more complex than equity.

Key principles:

  • Risk only 1-2% per trade
  • Account for margin requirements
  • Consider assignment risk
  • Use spreads to reduce risk
  • Never risk more than you can afford to lose

Simple rule: If you're not sure, use smaller position size.

The 2% Rule - Simple Math That Protects Your Capital

· 7 min read
Karthik
Founder, TradeLyser

One rule. One number. One decision.

2%

That's all you need to know to protect your trading account.

Let me show you why this simple rule is the difference between survival and destruction.

What Is the 2% Rule?

The 2% Rule: Never risk more than 2% of your account on a single trade.

That's it.

Not 3%. Not 5%. Not 10%.

2%.

The Math

Account: ₹5,00,000
2% Risk: ₹10,000 per trade
Stop Loss: ₹50 away
Position Size: ₹10,000 ÷ ₹50 = 200 shares

If stopped out: Lose exactly ₹10,000 (2%)
Account remaining: ₹4,90,000 (98%)


Why 2%? Why Not More?

The Survival Math

Let's see what happens with different risk levels:

Scenario: 10-Loss Streak (happens to everyone)

At 2% risk per trade:

  • Loss 1: ₹5,00,000 → ₹4,90,000 (-2%)
  • Loss 2: ₹4,90,000 → ₹4,80,200 (-2%)
  • Loss 3: ₹4,80,200 → ₹4,70,596 (-2%)
  • ...
  • Loss 10: ₹4,08,000 → ₹3,99,840 (-2%)
  • Total loss: 20%
  • Account survives

At 5% risk per trade:

  • Loss 1: ₹5,00,000 → ₹4,75,000 (-5%)
  • Loss 2: ₹4,75,000 → ₹4,51,250 (-5%)
  • Loss 3: ₹4,51,250 → ₹4,28,688 (-5%)
  • ...
  • Loss 10: ₹2,99,000 → ₹2,84,000 (-5%)
  • Total loss: 43%
  • Account damaged

At 10% risk per trade:

  • Loss 1: ₹5,00,000 → ₹4,50,000 (-10%)
  • Loss 2: ₹4,50,000 → ₹4,05,000 (-10%)
  • Loss 3: ₹4,05,000 → ₹3,64,500 (-10%)
  • ...
  • Loss 10: ₹1,95,000 → ₹1,75,000 (-10%)
  • Total loss: 65%
  • Account devastated

The Recovery Math

How much do you need to recover?

After 20% loss (2% rule):

  • Need +25% to recover
  • Achievable with good trading

After 43% loss (5% rule):

  • Need +75% to recover
  • Very difficult

After 65% loss (10% rule):

  • Need +186% to recover
  • Nearly impossible

The 2% rule keeps you in the game.


Real Examples

Example 1: Equity Trading

Setup:

  • Account: ₹3,00,000
  • Stock: RELIANCE
  • Entry: ₹2,500
  • Stop: ₹2,450 (₹50 away)

2% Calculation:

  • Risk amount: ₹3,00,000 × 2% = ₹6,000
  • Position size: ₹6,000 ÷ ₹50 = 120 shares
  • Investment: 120 × ₹2,500 = ₹3,00,000
  • Risk: 120 × ₹50 = ₹6,000 ✓

If stopped out: Lose ₹6,000 (exactly 2%)

Example 2: Options Trading

Setup:

  • Account: ₹5,00,000
  • NIFTY 24500 CE @ ₹150
  • Stop: ₹120 (₹30 away)
  • Lot size: 50

2% Calculation:

  • Risk amount: ₹5,00,000 × 2% = ₹10,000
  • Position size: ₹10,000 ÷ (₹30 × 50) = 6.67 lots
  • Round down: 6 lots
  • Investment: 6 × 50 × ₹150 = ₹45,000
  • Risk: 6 × 50 × ₹30 = ₹9,000 ✓

If stopped out: Lose ₹9,000 (1.8% - even safer)

Example 3: Futures Trading

Setup:

  • Account: ₹10,00,000
  • NIFTY Futures @ 24,500
  • Stop: 24,400 (100 points)
  • Lot size: 50

2% Calculation:

  • Risk amount: ₹10,00,000 × 2% = ₹20,000
  • Position size: ₹20,000 ÷ (100 × 50) = 4 lots
  • Investment: 4 × 50 × 24,500 = ₹49,00,000
  • Margin required: ~₹2,45,000
  • Risk: 4 × 50 × 100 = ₹20,000 ✓

If stopped out: Lose ₹20,000 (exactly 2%)


Common Objections to the 2% Rule

Objection #1: "2% Is Too Small"

"I need bigger positions to make money"

Reality check:

  • 2% × 20 trades = 40% of account at risk
  • If you win 60% of trades, you're profitable
  • Compounding works over time

Example:

  • Start: ₹5,00,000
  • Win 60% of trades (2% each)
  • After 100 trades: ₹8,50,000
  • 70% growth with 2% risk

Objection #2: "I'm Confident This Will Work"

"This trade is 100% sure"

Reality:

  • No trade is 100% sure
  • Even 80% probability trades lose 20% of time
  • Confidence ≠ accuracy

Better approach:

  • Trade with 2% risk
  • If you're right, you make money
  • If you're wrong, you survive

Objection #3: "I Need to Make Money Fast"

"I can't wait for slow growth"

Reality:

  • Fast money = Fast losses
  • Slow money = Sustainable money
  • Surviving > Thriving

Math:

  • 2% risk: Survive losing streaks
  • 10% risk: Blow up account
  • Dead traders make 0%

Objection #4: "My Account Is Too Small"

"₹50,000 account, 2% = ₹1,000, too small"

Solutions:

  1. Build account first (paper trade)
  2. Use 2% of larger amount (₹1,00,000 = ₹2,000)
  3. Accept smaller positions (better than blowing up)

Remember: Small account + big risk = No account


Advanced: When to Use Less Than 2%

Use 1% When:

High volatility markets:

  • VIX > 20
  • Earnings season
  • Major news events

Testing new strategies:

  • First 20 trades
  • Unfamiliar instruments
  • Different timeframes

After losses:

  • Recent losing streak
  • Emotional state compromised
  • Account drawdown > 10%

Use 0.5% When:

Account < ₹1,00,000:

  • Preserve capital
  • Learn without risk
  • Build confidence

Very volatile instruments:

  • Penny stocks
  • Cryptocurrency
  • High-beta stocks

The 2% Rule in Practice

Daily Implementation

Before every trade:

  1. Calculate 2% of account
  2. Determine stop loss distance
  3. Calculate position size
  4. Verify: Risk ≤ 2%
  5. Enter trade

Example checklist:

Account: ₹5,00,000
2% Risk: ₹10,000
Entry: ₹1,000
Stop: ₹980 (₹20 away)
Position Size: ₹10,000 ÷ ₹20 = 500 shares
Investment: 500 × ₹1,000 = ₹5,00,000
Risk: 500 × ₹20 = ₹10,000 ✓

Weekly Review

Check:

  • Did I follow 2% rule every trade?
  • What was my average risk per trade?
  • Any trades exceeded 2%?

If yes: Why? How to prevent?

Monthly Analysis

Track:

  • Total risk taken
  • Number of 2%+ trades
  • Correlation with losses

Goal: 100% adherence to 2% rule


Portfolio Heat: Multiple Positions

The Problem

You have 3 open positions:

  • Position 1: 2% risk
  • Position 2: 2% risk
  • Position 3: 2% risk
  • Total portfolio heat: 6%

This is acceptable.

The Danger Zone

You have 5 open positions:

  • Each: 2% risk
  • Total portfolio heat: 10%

This is dangerous.

Real Results: Before & After

Trader A: No Risk Management

Before 2% rule:

  • Risk per trade: 5-10%
  • Account: ₹5,00,000
  • After 5 losses: ₹2,50,000 (-50%)
  • Emotional state: Devastated
  • Trading: Stopped

Trader B: With 2% Rule

After implementing 2% rule:

  • Risk per trade: 2%
  • Account: ₹5,00,000
  • After 5 losses: ₹4,50,000 (-10%)
  • Emotional state: Calm
  • Trading: Continued

Same strategy. Different risk management. Different outcome.


The Psychology of 2%

Why It Works

Small losses:

  • Don't hurt emotionally
  • Don't affect confidence
  • Don't trigger revenge trading
  • Allow continued trading

Large losses:

  • Devastate emotionally
  • Destroy confidence
  • Trigger revenge trading
  • Stop trading

The Compound Effect

Month 1: Follow 2% rule
Month 2: Still following (habit formed)
Month 3: Automatic (no thinking required)
Month 6: Different trader (disciplined)
Month 12: Profitable trader (survived to learn)


Common Mistakes

Mistake #1: "Just This Once"

"This trade is special, I'll risk 5%"

Problem: Once becomes always

Solution: Never exceed 2%. Ever.

Mistake #2: Moving Stops

"I'll widen the stop to 3% risk"

Problem: Defeats the purpose

Solution: Set stop first, then calculate position

Mistake #3: Averaging Down

"I'll add to losing position"

Problem: Increases risk beyond 2%

Solution: One position per trade

Mistake #4: No Stop Loss

"I'll hold until it comes back"

Problem: Risk becomes unlimited

Solution: Always set stop before entry


The Bottom Line

The 2% rule isn't about making money.

It's about staying alive.

You can't make money if you're not trading.

You can't trade if you blow up your account.

The 2% rule ensures you survive to trade another day.

Simple. Powerful. Essential.

Position Sizing - The Most Important Skill Nobody Teaches

· 7 min read
Karthik
Founder, TradeLyser

Pop quiz: What's the most important factor in long-term trading success?

  • Strategy? ❌
  • Win rate? ❌
  • Risk:reward? ❌

Answer: Position sizing.

You can have the best strategy in the world, but if you size positions incorrectly, you'll blow up your account.

Let me show you why—and exactly how to size positions like a professional.

The Brutal Math of Trading

Consider two traders with identical strategies:

Trader A: Poor Position Sizing

  • Win Rate: 60%
  • Avg Win: ₹5,000
  • Avg Loss: ₹5,000
  • But: Risks 20% per trade

Trader B: Smart Position Sizing

  • Win Rate: 60%
  • Avg Win: ₹5,000
  • Avg Loss: ₹5,000
  • Risks 2% per trade

Who survives?

After hitting 3 losses in a row (which happens to all traders):

Trader A:

  • Loss 1: -20% (₹1,00,000 → ₹80,000)
  • Loss 2: -20% (₹80,000 → ₹64,000)
  • Loss 3: -20% (₹64,000 → ₹51,200)
  • Total: -48.8%
  • Needs +95% to recover

Trader B:

  • Loss 1: -2% (₹1,00,000 → ₹98,000)
  • Loss 2: -2% (₹98,000 → ₹96,040)
  • Loss 3: -2% (₹96,040 → ₹94,119)
  • Total: -5.9%
  • Needs +6.3% to recover

See the difference? Same strategy. Massively different outcomes.

What Is Position Sizing?

Position sizing answers one question:

"How much should I risk on this trade?"

Not: "How many shares should I buy?"
Not: "How much can I afford?"
But: "How much am I willing to lose if I'm wrong?"


The Fixed Percentage Method

Rule: Risk a fixed percentage of your capital per trade.

Standard Risk Levels:

Risk %TypeFor
0.5%Ultra ConservativeLarge accounts, risk-averse
1%ConservativeMost professional traders
2%ModerateExperienced retail traders
3-5%AggressiveHigh risk tolerance, small accounts
10%+SuicidalRecipe for disaster

Most pros use 1-2% per trade.

The Formula:

Position Size = (Account Size × Risk %) / Stop Loss Distance

Example:
Account: ₹5,00,000
Risk: 2% = ₹10,000
Entry: ₹1,000
Stop: ₹980 (20 points away)

Position Size = ₹10,000 / ₹20 = 500 shares

If stopped out: Lose exactly ₹10,000 (2%)

Real Examples

Example 1: Equity Trade

Setup:

  • Account: ₹3,00,000
  • Risk: 1% = ₹3,000
  • Stock: RELIANCE
  • Entry: ₹2,500
  • Stop: ₹2,450 (₹50 away)

Calculation:

Position Size = ₹3,000 / ₹50 = 60 shares

Investment: 60 × ₹2,500 = ₹1,50,000
Risk: 60 × ₹50 = ₹3,000 ✓

Example 2: Options Trade

Setup:

  • Account: ₹5,00,000
  • Risk: 2% = ₹10,000
  • NIFTY 24500 CE @ ₹150
  • Stop: ₹120 (₹30 away)
  • Lot size: 50

Calculation:

Position Size = ₹10,000 / (₹30 × 50)
= ₹10,000 / ₹1,500
= 6.67 lots
= 6 lots (round down)

Investment: 6 lots × 50 × ₹150 = ₹45,000
Risk: 6 lots × 50 × ₹30 = ₹9,000 ✓

Example 3: Futures Trade

Setup:

  • Account: ₹10,00,000
  • Risk: 1.5% = ₹15,000
  • NIFTY Futures @ 24,500
  • Stop: 24,400 (100 points)
  • Lot size: 50

Calculation:

Position Size = ₹15,000 / (100 × 50)
= ₹15,000 / ₹5,000
= 3 lots

Investment: 3 lots × 50 × 24,500 = ₹36,75,000
(Margin required: ~₹1,80,000)
Risk: 3 lots × 50 × 100 = ₹15,000 ✓

Advanced Position Sizing Strategies

1. Kelly Criterion

Mathematical formula to maximize long-term growth:

Kelly % = (Win Rate × Avg Win - (1 - Win Rate) × Avg Loss) / Avg Win

Example:
Win Rate: 60%
Avg Win: ₹5,000
Avg Loss: ₹3,000

Kelly = (0.6 × 5000 - 0.4 × 3000) / 5000
= (3000 - 1200) / 5000
= 0.36 = 36%

Problem: 36% is too aggressive for most traders.

Solution: Use Half Kelly or Quarter Kelly

Half Kelly = 18%
Quarter Kelly = 9%

Recommendation: Start with Quarter Kelly, max Half Kelly.

2. Volatility-Adjusted Sizing

Adjust position size based on market volatility:

Position Size = Base Size × (Normal VIX / Current VIX)

Example:
Normal VIX: 15
Current VIX: 20
Base position: 2%

Adjusted = 2% × (15/20) = 1.5%

Result: Automatically reduce size in high volatility.

3. Confidence-Based Sizing

Scale position size based on setup quality:

Setup QualityPosition Size
A+ Setup2.0%
A Setup1.5%
B Setup1.0%
C SetupDon't trade

Example:

  • A+ setup with all conditions: 2% risk
  • A setup with most conditions: 1.5% risk
  • Marginal setup: Skip it

4. Pyramid Scaling

Add to winning positions:

Initial position: 1%
After +50% of target: Add 0.5%
After +75% of target: Add 0.25%

Total risk: 1.75% (but averaged price is better)

Rule: Always trail stops on entire position.


Position Sizing Mistakes to Avoid

Mistake #1: Fixed Share Quantity

Wrong: "I always buy 100 shares"

Why wrong: 100 shares of ₹50 stock = ₹5,000
100 shares of ₹2,500 stock = ₹2,50,000

Fix: Calculate position size based on risk.

Mistake #2: Using All Available Capital

Wrong: "I have ₹1L, so I'll use it all"

Why wrong: One bad trade = 100% loss

Fix: Never use more than 10-20% of capital per trade.

Mistake #3: Ignoring Stop Loss

Wrong: "I'll buy ₹1L worth and hope"

Why wrong: No defined risk = no position sizing

Fix: Always set stop before calculating position size.

Mistake #4: Revenge Sizing

Wrong: "I lost ₹10K, so I'll risk ₹20K to win it back"

Why wrong: Doubling risk doubles ruin probability

Fix: Stick to your % rule, especially after losses.

Mistake #5: Over-Leveraging

Wrong: "I'll use 10x leverage because I'm confident"

Why wrong: Confidence doesn't reduce risk

Fix: Higher leverage = smaller position size.


Portfolio Heat: Managing Multiple Positions

Portfolio Heat = Total risk across all open positions

Example:

Trade 1: 2% risk
Trade 2: 2% risk
Trade 3: 1.5% risk

Total Portfolio Heat: 5.5%

Safe Portfolio Heat Levels:

Total HeatAssessment
0-2%Very safe
2-5%Moderate
5-8%High
8-10%Very high
10%+Danger zone

Rule: Keep portfolio heat below 6-8% maximum.


Position Sizing for Different Account Sizes

Small Account (₹50,000 - ₹2,00,000)

Challenges:

  • Lot sizes too large
  • Limited diversification
  • High percentage swings

Strategy:

  • Focus on equity (not F&O)
  • 2-3% risk per trade
  • Maximum 2-3 positions
  • Accept concentration risk

Medium Account (₹2,00,000 - ₹10,00,000)

Advantages:

  • Can trade F&O
  • Some diversification possible
  • More flexibility

Strategy:

  • 1.5-2% risk per trade
  • Maximum 3-4 positions
  • Mix of equity and F&O
  • Portfolio heat: 6% max

Large Account (₹10,00,000+)

Advantages:

  • Full diversification
  • Multiple strategies
  • Professional management possible

Strategy:

  • 0.5-1% risk per trade
  • Multiple positions (5-10)
  • Different strategies
  • Portfolio heat: 5% max

The Math of Survival

Question: How many losses in a row can you survive?

At 1% risk per trade:

  1. -1% → 99% remaining
  2. -1% → 98.01% remaining
  3. -1% → 97.03% remaining ... 10 losses: 90.44% remaining 20 losses: 81.79% remaining

Survivable.

At 10% risk per trade:

  1. -10% → 90% remaining
  2. -10% → 81% remaining
  3. -10% → 72.9% remaining ... 10 losses: 34.87% remaining 20 losses: 12.16% remaining

Account destroyed.

Lesson: Small position sizes = longevity.


Position Sizing Checklist

Before every trade:

  • What's my account size?
  • What % am I risking? (1-2% recommended)
  • Where's my stop loss?
  • What's the distance to stop (in ₹)?
  • What's my position size calculation?
  • Does this exceed portfolio heat limits?
  • Can I afford to be wrong?
  • Have I rounded down (not up)?

If any answer is unclear: Don't take the trade.
