# Risk Management for Traders
The single most important factor determining trading success.
---
## Why Risk Management Matters
**The brutal truth:**
- 90% of traders lose money
- Most blow up their accounts
- #1 reason: Poor risk management
**What separates winners from losers:**
- NOT better analysis
- NOT better indicators
- NOT market prediction
- **Risk management and discipline**
**Your job as a trader:**
- Protect capital FIRST
- Make money SECOND
---
## The 1% Rule
**Never risk more than 1% of account on single trade**
### Why 1%?
**Survival math:**
- 10 losses in a row = -10% drawdown
- 20 losses in a row = -20% drawdown
- Still in the game
**Compare to 5% risk:**
- 10 losses in a row = -50% drawdown
- Need 100% return just to break even
- Likely game over
### How to Calculate
```
Risk Amount = Account Size × 0.01
Example:
$50,000 account × 1% = $500 max risk per trade
```
### Position Sizing with 1% Rule
```
Shares = Risk Amount / (Entry - Stop)
Example:
- Account: $50,000
- Risk: $500 (1%)
- Entry: $100
- Stop: $98
- Risk per share: $2
- Position: $500 / $2 = 250 shares
```
**Key insight:** Position SIZE changes, but RISK stays constant
---
## Daily Loss Limits
**Hard stop when you hit daily loss limit**
### Recommended Limits
| Trader Type | Daily Loss Limit |
|-------------|------------------|
| Conservative | -1% |
| Moderate | -2% |
| Aggressive | -3% |
### Why Daily Limits Matter
**Prevents:**
- Revenge trading
- Emotional spirals
- Blowup days
- Tilt-induced disasters
**Example:**
- $50,000 account
- 2% daily limit = -$1,000
- Hit limit → DONE for the day
- No exceptions
### What to Do When Hit
1. Close ALL positions
2. Step away from computer
3. Physical activity (walk/exercise)
4. Review trades later (not now)
5. Resume next day with clear head
**Remember:** There's always tomorrow
---
## Maximum Drawdown
**Stop trading at X% drawdown from peak**
### Recommended Limits
- Conservative: 10%
- Moderate: 15%
- Aggressive: 20%
### When Hit
1. **STOP trading immediately**
2. Take minimum 1 week break
3. Full trade review
4. Identify systematic issues
5. Paper trade only
6. Return with reduced size
### Why This Matters
**Psychology of drawdown:**
- -10% requires +11% to recover
- -20% requires +25% to recover
- -50% requires +100% to recover
**Each % down becomes harder to recover**

## Risk:Reward Ratios
**Only take trades with favorable R:R**
### Minimum Standards
**Conservative:** 3:1
**Moderate:** 2:1
**Aggressive:** 1.5:1
### The Math
With 2:1 R:R, you can be profitable at 40% win rate:
```
10 trades:
- 4 wins × 2R = +8R
- 6 losses × 1R = -6R
- Net: +2R profit
```
### How to Calculate
```
R = Risk (Entry - Stop)
Reward = Target - Entry
R:R = Reward / Risk
Example:
- Entry: $100
- Stop: $98 (Risk = $2)
- Target: $106 (Reward = $6)
- R:R = $6 / $2 = 3:1 ✓
```
**Rule:** If R:R < your minimum → SKIP THE TRADE

## Position Sizing Methods
### 1. Fixed Dollar Risk (Recommended)
**Same dollar risk every trade**
```
Shares = Risk $ / (Entry - Stop)
```
**Pros:**
- Simple and consistent
- Easy to track
- Protects capital
**Cons:**
- Doesn't scale with wins/losses
---
### 2. Fixed Percentage Risk
**Same % risk every trade**
```
Shares = (Account × Risk %) / (Entry - Stop)
```
**Pros:**
- Scales with account
- Compounds wins
- Simple
**Cons:**
- Also compounds losses
---
### 3. Volatility-Based (ATR)
**Position size based on volatility**
```
Risk $ / (ATR × Multiplier)
```
**Pros:**
- Adapts to market conditions
- Prevents whipsaw
**Cons:**
- More complex
- Requires calculation
---
### 4. Kelly Criterion (Advanced)
**Optimal position sizing based on edge**
```
Kelly % = (Win Rate × Avg Win - Loss Rate × Avg Loss) / Avg Win
```
**WARNING:**
- Can be very aggressive
- Use fractional Kelly (1/4 or 1/2)
- Only for experienced traders
- Requires accurate statistics
---
## Stop-Loss Strategies
### Never Trade Without Stops
**Why stops are mandatory:**
- Limits losses
- Removes emotion
- Protects from disasters
- Enables risk calculation
**No exceptions. Ever.**
### Stop-Loss Methods
**1. Fixed Percentage**
- X% below entry
- Simple and clear
- Example: 2% below entry
**2. Technical Level**
- Below support
- Below swing low
- Makes logical sense
**3. ATR-Based**
- 1.5-2× Average True Range
- Adapts to volatility
- Prevents whipsaw
**4. Time Stop**
- Exit if no progress in X days
- Frees capital
- Cuts losers
### Stop-Loss Rules
**✓ DO:**
- Set stop BEFORE entry
- Use actual stop orders (not mental)
- Place stops at logical levels
- Honor stops always
**✗ NEVER:**
- Move stop further from entry
- Remove stop "just this once"
- Use mental stops
- Hope price comes back
---
## Position Concentration
**Don't put all eggs in one basket**
### Maximum Position Limits
**Single position:**
- Conservative: 10% of account
- Moderate: 20% of account
- Aggressive: 30% of account
**Sector exposure:**
- Maximum 30-40% in single sector
- Diversify across sectors
- Correlation matters
**Total exposure:**
- Day trading: 100% (close daily)
- Swing trading: 60-80%
- Position trading: Varies
### Why Concentration Matters
**Example:**
- 50% in one position
- Stock drops 20%
- Account drops 10%
- Hard to recover
**Better:**
- 10% in one position
- Stock drops 20%
- Account drops 2%
- Manageable
---
## Correlation Risk
**Avoid correlated positions**
### Understanding Correlation
**High correlation example:**
- Long tech stock A
- Long tech stock B
- Both move together
- Double exposure to tech risk
**Better diversification:**
- Different sectors
- Different market caps
- Different strategies
- True diversification
---
## Leverage and Margin
**Leverage amplifies BOTH gains and losses**
### Margin Risk
**2:1 Margin:**
- 50% loss = margin call
- Forced liquidation
- Game over
**Recommended:**
- Use margin sparingly
- Never max out margin
- Maintain buffer
- Understand margin requirements
### Options Leverage
**Options can expire worthless**
- 100% loss possible
- Time decay (theta)
- Volatility risk (vega)
- Requires different risk management
**Options risk limit:**
- Max 5-10% of account in options
- Treat each option as high risk
- Never bet the farm

## Risk Management Checklist
**Before EVERY trade:**
- [ ] Position size calculated
- [ ] Risk ≤ 1% (or your limit)
- [ ] Stop-loss identified
- [ ] R:R ≥ 2:1 (or your minimum)
- [ ] Within daily loss limit
- [ ] Not overexposed to sector
- [ ] Account for correlation

**If ANY unchecked → DON'T TAKE TRADE**
---
## Account Preservation

1. **Never go all-in**
- Keep reserves
- Opportunities come again
2. **Accept losses quickly**

- Clear your head
5. **Reduce size in drawdown**

## Common Risk Management Mistakes
### ❌ Fatal Errors
**1. No stop-loss**
Result: One trade wipes account
**2. Risk too much per trade**
Result: Few losses = blown account
**3. Moving stops**
Result: Invalidates risk management
**4. Revenge trading**
Result: Emotional decisions, bigger losses
**5. Averaging down**
Result: Doubling down on mistakes
**6. Over-leveraging**
Result: Margin call, forced exit
**7. Ignoring correlation**
Result: Concentrated risk in disguise
### ✓ Best Practices
**1. Consistent position sizing**
Same risk every trade
**2. Hard daily loss limits**
Stop when hit, no exceptions
**3. Honest stop placement**
Logical levels, not wishes
**4. R:R minimum**
Quality over quantity

## Risk vs Reward Balance
**High Probability vs High R:R**
### High Win Rate (60-70%)
- Smaller R:R (1.5:1)
- More trades
- Steady equity curve
- Example: Mean reversion
### High R:R (3:1+)
- Lower win rate (30-40%)
- Fewer trades
- Volatile equity curve
- Example: Trend following
**Both can be profitable if managed correctly**

## Position Sizing Examples
### Example 1: Moderate Risk
```
Account: $50,000
Risk per trade: 1% = $500
Entry: $50
Stop: $48
Risk per share: $2
Position: $500 / $2 = 250 shares
Position value: $12,500 (25% of account)
Actual risk: $500 (1% of account)
```
### Example 2: Tight Stop
```
Account: $50,000
Risk per trade: 1% = $500
Entry: $100
Stop: $99
Risk per share: $1
Position: $500 / $1 = 500 shares
Position value: $50,000 (100% of account)
Actual risk: $500 (1% of account)
```
**Key:** Position SIZE varies, but RISK stays constant
