The 2% Rule - Simple Math That Protects Your Capital

· 7 min read

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.

Safe Portfolio Heat Levels

Total HeatAssessmentAction
0-4%Very safeContinue
4-6%ModerateMonitor
6-8%HighReduce new positions
8-10%Very highStop new trades
10%+Danger zoneClose positions

Rule: Keep total portfolio heat below 6-8%


The 2% Rule Calculator

Formula

Position Size = (Account Size × 2%) ÷ Stop Loss Distance

Example:
Account: ₹5,00,000
2% Risk: ₹10,000
Stop Distance: ₹50
Position Size: ₹10,000 ÷ ₹50 = 200 shares

TradeLyser Integration

Auto-calculation:

  1. Enter account size
  2. Enter entry price
  3. Enter stop price
  4. TradeLyser calculates position size
  5. Shows risk percentage
  6. Alerts if > 2%

No math required. No errors possible.


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.

Automated Rule Tracking - Let Software Enforce Your Discipline

· 10 min read
Karthik
Founder, TradeLyser

The problem with trading rules:

You create them when you're calm.
You break them when you're emotional.

Why?

Because willpower fails under pressure.

The solution:

Don't rely on willpower. Use automation.

The Willpower Myth

Scenario: Rule Without Automation

Your rule: "Stop trading after 2 consecutive losses"

What happens:

Loss 1: -₹2,000 ("Bad luck, next one will work")
Loss 2: -₹2,500 ("I should stop... but let me try one more")
Rule broken
Loss 3: -₹5,000 ("Now I'm in trouble")

Why you broke it:

  • Emotion overpowered logic
  • "Just one more" seemed reasonable
  • No physical barrier to prevent it

Scenario: Rule With Automation

Your rule: "Stop trading after 2 consecutive losses" (automated)

What happens:

Loss 1: -₹2,000 (Alert: "1st loss")
Loss 2: -₹2,500 (Alert: "2nd loss - STOP TRADING")
Attempt Loss 3: BLOCKED "Max losses reached for today"

Why you followed it:

  • Software enforced it
  • No way to override (designed intentionally)
  • Removed human decision

Result: -₹4,500 loss vs -₹12,000+ loss


What Are Automated Rules?

Automated rules are pre-defined trading guidelines that:

✅ Monitor your trading in real-time
✅ Alert you when approaching limits
✅ Block actions that violate rules
✅ Track adherence automatically
✅ Generate compliance reports

Key difference from manual rules:

Manual: "I should follow this" (relies on discipline)
Automated: "System enforces this" (discipline built-in)


Types of Automated Rules

Category 1: Risk Management Rules

Rule: Maximum Risk Per Trade

Setup:

  • Max risk: 2% of account per trade
  • Account: ₹5,00,000

Real Results: Before & After Automation

Case Study: Amit - Overtrader

Before Automation (6 months):

  • Trades per day: 8-12
  • Win rate: 45%
  • Biggest problem: Revenge trading
  • Monthly P&L: +₹12K (barely profitable)
  • Emotional state: Stressed

Rules Implemented:

  1. Max 3 trades per day
  2. Stop after 2 losses
  3. 30-min break between trades
  4. Daily loss limit: ₹6,000

After Automation (6 months):

  • Trades per day: 2-3 (67% reduction)
  • Win rate: 62% (selective = quality)
  • Revenge trading: Impossible (blocked by software)
  • Monthly P&L: +₹38K (3x improvement)
  • Emotional state: Calm, in control

Amit's words: "The rules saved me from myself. I physically CAN'T revenge trade anymore. Best thing I ever did."


Advanced: Rule Combinations

Rules can work together:

Combo #1: Streak Protection

Rule A: After 2 wins, reduce position size 25%
(Prevents overconfidence)

Rule B: After 2 losses, mandatory break
(Prevents revenge trading)

Result: Protected from both extremes

Combo #2: Time & Risk

Rule A: No trading after 2 PM
(Your stats show you lose afternoon)

Rule B: If already in trade at 2 PM, exit by 2:30 PM
(Minimize exposure)

Result: Time-based risk management

Combo #3: Ladder Risk Management

Rule A: Position 1 = 2% risk
Rule B: Position 2 = 1.5% risk
Rule C: Position 3 = 1% risk
Rule D: No position 4 (max 3 positions)

Result: Decreasing size = safer

Common Questions

Q: Won't rules prevent me from taking good opportunities?

A: They'll prevent you from taking bad "opportunities" that feel good in the moment. Your "good opportunities" should fit your rules.

Q: What if I want to override a rule?

A: Some rules allow override with mandatory note explaining why. Others are strict (no override). You choose when creating rule.

Q: Can I temporarily disable a rule?

A: Yes, but you must:

  1. Provide reason (logged)
  2. Set re-enable time
  3. Confirm you understand risk

Q: What if market conditions change mid-day?

A: Rules can be time-based (e.g., "No Strategy A after 1 PM" is fine). Total disabling of core rules is not recommended.

Q: How many rules should I have?

A: Start with 3-5 core rules. Add more only if needed. Too many rules = complexity = failure to follow.


The Bottom Line

Trading without automated rules:

  • Relies on willpower
  • Willpower fails under stress
  • Discipline breaks
  • Account suffers

Trading with automated rules:

  • Relies on systems
  • Systems don't fail
  • Discipline enforced
  • Account protected

You wouldn't drive without brakes.
Don't trade without automated rules.
