# Risk Management

## Position Sizing & Lot Calculation

Professional risk management is the foundation of profitable trading. BananaEA offers three position sizing methods to match your trading style and account management preferences.

***

## `LotMethod` - Position Sizing Method

### Overview

**What it does:** Determines how BananaEA calculates lot size for each trade.

**Available methods:**

1. **LM\_RISK\_PERCENT** — Risk percentage of equity per trade (professional standard)
2. **LM\_RISK\_AMOUNT** — Risk fixed currency amount per trade
3. **LM\_FIXED\_SIZE** — Use same lot size every trade (simple/predictable)

***

## Method 1: Risk Percent (Recommended)

### `RiskPercent`

**What it does:** Risks a percentage of account equity per trade.

**Configuration:**

* **Default:** 1.0%
* **Range:** 0.1% – 10.0%
* **Recommended:** 1.0% – 2.0% for most traders

**How it works:**

```
Example with $10,000 account:
RiskPercent = 2.0%
Maximum risk = $200 per trade

If SL = 20 pips:
Lot size = $200 ÷ (20 pips × pip value) = Auto-calculated

If SL = 50 pips:
Lot size = $200 ÷ (50 pips × pip value) = Auto-calculated (smaller lots)
```

**Key advantage:**

* Risk stays constant as percentage (always 2% per trade)
* Lot size adjusts automatically based on SL distance
* Wider SL = Smaller lot size (maintains constant $ risk)
* Tighter SL = Larger lot size (maintains constant $ risk)

### Risk Percentage Guidelines

| Risk %    | Trader Type        | Max Drawdown Risk | Recovery Difficulty |
| --------- | ------------------ | ----------------- | ------------------- |
| 0.5-1.0%  | Ultra-conservative | Very low          | Easy                |
| 1.0-2.0%  | Professional       | Low-moderate      | Moderate            |
| 2.0-3.0%  | Aggressive         | Moderate-high     | Challenging         |
| 3.0-5.0%  | Very aggressive    | High              | Difficult           |
| 5.0-10.0% | Extremely risky    | Very high         | Very difficult      |

**Best practices:**

* **Beginners:** Start with 1.0% until you understand EA behavior
* **Experienced:** 2.0% is professional standard
* **Prop firms:** Follow firm requirements (typically 1-2%)
* **Never exceed 5%** per trade (extreme risk)

### Account Growth Compounding

**Advantage of percentage-based risk:**

```
Starting account: $10,000
RiskPercent = 2.0%

Trade 1: Risk $200 (2% of $10,000)
Win $600 → New balance $10,600

Trade 2: Risk $212 (2% of $10,600) ← Automatic compounding
Win $636 → New balance $11,236

Trade 3: Risk $225 (2% of $11,236) ← Continues growing
```

**With fixed lot, you miss this compounding effect.**

***

## Method 2: Fixed Amount

### `RiskAmount`

**What it does:** Risks the same currency amount per trade.

**Configuration:**

* **Example:** 100.0 (risk $100 or €100 or £100 per trade)
* **Range:** Minimum = 10.0, Maximum = account-dependent
* **Currency:** Same as account base currency

**How it works:**

```
RiskAmount = 100.0 (USD)

Every trade risks exactly $100:
- If SL = 20 pips → Larger lot size
- If SL = 50 pips → Smaller lot size
- Account grows from $10,000 → $15,000 → Still risks $100/trade
```

**Use cases:**

* Precise dollar risk control for personal rules
* Prop firm challenges with specific $ risk limits
* Managing multiple accounts with consistent $ risk

**Limitations:**

* No compounding effect (fixed $ risk as account grows)
* Must manually adjust RiskAmount as account grows
* Less efficient capital utilization

***

## Method 3: Fixed Lot

### `LotSize`

**What it does:** Uses the same lot size for every trade.

**Configuration:**

* **Default:** 0.1 (mini lot)
* **Range:** 0.01 – 100.0 (broker-dependent)
* **Common sizes:**
  * 0.01 = Micro lot ($0.10/pip on forex majors)
  * 0.1 = Mini lot ($1/pip on forex majors)
  * 1.0 = Standard lot ($10/pip on forex majors)

**How it works:**

```
LotSize = 0.1 (mini lot)

Every trade:
- Same lot size (0.1)
- Risk varies based on SL distance
- SL = 20 pips → Risk $20
- SL = 50 pips → Risk $50
```

**Use cases:**

* Testing strategies with consistent position sizing
* Very small accounts (< $500) where percentage risk is too small
* Learning EA behavior without complex calculations

**Limitations:**

* Risk per trade varies based on SL distance (inconsistent)
* No risk protection (could risk 10% on one trade, 2% on another)
* Requires manual lot size adjustments as account grows

**Tip:** Start small (0.01–0.05) while learning.

## Choosing the Right Method

### Decision Matrix

**Use LM\_RISK\_PERCENT when:**

* ✅ You want professional money management
* ✅ You want consistent percentage risk per trade
* ✅ You want automatic compounding as account grows
* ✅ You're trading with $1,000+ account
* ✅ You want to scale position size with SL distance

**Use LM\_RISK\_AMOUNT when:**

* ✅ You have specific dollar risk limits (e.g., prop firm rules)
* ✅ You want precise dollar risk control
* ✅ You're managing multiple accounts with same $ risk
* ✅ You prefer manual compounding decisions

**Use LM\_FIXED\_SIZE when:**

* ✅ You have very small account (< $500)
* ✅ You're testing strategies with consistent sizing
* ✅ You want simplest approach while learning
* ⚠️ Understand risk varies per trade (not recommended long-term)

## Risk Management Best Practices

### The 1-2-3 Rule

**Golden risk management rules:**

1. **Per-trade risk:** 1-2% of account
2. **Total exposure:** ≤ 10% of account (all open trades combined)
3. **Daily loss limit:** 3-5% maximum

**Example with $10,000 account:**

```
Per-trade risk: 2% = $200/trade
MaxOpenTrades: 3
Total exposure: 3 trades × 2% = 6% ($600 max)
Daily loss limit: 5% = $500 stop trading for the day
```

### Account Size Recommendations

| Account Size     | Recommended Risk % | Max Open Trades | Total Exposure |
| ---------------- | ------------------ | --------------- | -------------- |
| $500 - $1,000    | 1.0%               | 1-2             | 2-3%           |
| $1,000 - $5,000  | 1.5%               | 2-3             | 4.5-6%         |
| $5,000 - $10,000 | 2.0%               | 3               | 6%             |
| $10,000+         | 2.0%               | 3-5             | 6-10%          |

### Drawdown Recovery

**Why low risk % matters:**

| Drawdown | Recovery Needed |
| -------- | --------------- |
| -10%     | +11.1%          |
| -20%     | +25%            |
| -30%     | +42.9%          |
| -50%     | +100%           |

**Lower risk per trade = Easier recovery from losses.**

***

## Prop Firm Trading

### Common Prop Firm Requirements

**Risk limits:**

* Maximum 1-2% risk per trade
* Maximum 5% daily loss limit
* Maximum 10% total drawdown

**BananaEA configuration for prop firms:**

```
LotMethod = LM_RISK_PERCENT
RiskPercent = 1.0  (conservative for phase 1)
MaxOpenTrades = 2-3  (limit exposure)
AllowMultipleTrades = false  (prevent scaling-in)
```

**Phase 1 strategy (getting funded):**

* Lower risk (1.0%)
* Conservative TP targets
* Strict daily loss limits

**Phase 2 strategy (funded account):**

* Moderate risk (1.5-2.0%)
* Balanced TP targets
* Continue strict risk management

***

## Advanced Risk Techniques

### Position Sizing Based on Win Rate

**Higher win rate strategies:**

* Can use tighter stops (lower SL multipliers)
* Can risk slightly higher % per trade
* Can scale-in more aggressively

**Lower win rate strategies:**

* Require wider stops (higher SL multipliers)
* Should risk lower % per trade
* Should avoid scaling-in

### Kelly Criterion (Advanced)

**Formula for optimal bet size:**

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

**Example:**

```
Win Rate = 50%, Avg Win = 5R, Loss Rate = 50%, Avg Loss = 1R
Kelly % = (0.5 × 5) - (0.5 × 1) / 5 = 40%

Recommended bet: 20-25% of Kelly (8-10% per trade)
BananaEA safe implementation: 2% per trade
```

**Why use fraction of Kelly:**

* Full Kelly is too aggressive (high volatility)
* 25% of Kelly is professional standard
* BananaEA's 2% default is conservative and safe

***

## Risk Monitoring

### Track These Metrics

**Per-trade metrics:**

* Risk % per trade (should be consistent)
* Actual $ risk per trade
* SL distance in pips
* Lot size used

**Portfolio metrics:**

* Total exposure (all open trades)
* Largest single trade risk
* Correlation between open trades
* Daily/weekly P\&L

### Warning Signs

**Reduce risk if:**

* ❌ Experiencing losing streak (5+ consecutive losses)
* ❌ Drawdown exceeds 15%
* ❌ Emotional decision-making increasing
* ❌ Account below comfortable level

**Increase risk when:**

* ✅ Consistent profitability over 100+ trades
* ✅ Account grown significantly (still keep % constant)
* ✅ Strategy proven on live account
* ⚠️ Never exceed 3-5% even when winning

## Troubleshooting

### Issue: Lot Size Too Small

**Possible causes:**

1. Risk % too low for account size
2. SL distance too wide
3. Account balance too small

**Solutions:**

* Increase `RiskPercent` (within safe limits)
* Use tighter SL distances
* Deposit more capital
* Consider using `RISK_FIXED_LOT` for very small accounts

### Issue: Lot Size Too Large

**Possible causes:**

1. Risk % too high
2. SL distance too tight
3. Calculation error

**Solutions:**

* Decrease `RiskPercent` to safe levels
* Verify SL/TP settings
* Check broker lot size limits
* Enable `ShowDebugLogs` to see lot calculations

### Issue: Inconsistent Risk

**If using LM\_FIXED\_SIZE:**

* This is normal behavior (risk varies with SL distance)
* Consider switching to `LM_RISK_PERCENT` for consistent risk

**If using LM\_RISK\_PERCENT:**

* Risk should be consistent
* Check for manual lot size overrides
* Verify no other EAs are modifying trades
