## 📊 Strategy Details

### Indicator System

#### EMA Lines (3 Base Lines)
All EMAs use period 30 with different price sources:

1. **EMA High** (Light Blue) - EMA of High prices
2. **EMA Medium** (Yellow) - EMA of Close prices
3. **EMA Low** (Orange) - EMA of Low prices

#### Border Lines (2 Dynamic Lines)
Calculated based on the range between EMAs:

1. **High Border** (Purple) = EMA High + (EMA Medium - EMA Low)
2. **Low Border** (Purple) = EMA Low - (EMA Medium - EMA Low)

**Example Calculation:**
```
EMA High = 3500
EMA Medium = 3400
EMA Low = 3300
Range = EMA Medium - EMA Low = 3400 - 3300 = 100

High Border = 3500 + 100 = 3600
Low Border = 3300 - 100 = 3200
```

### Signal Types

#### 1. Breakthrough Signal
- **Buy Signal:** Close price breaks above EMA High
- **Sell Signal:** Close price breaks below EMA Low
- **Purpose:** Triggers order opening

#### 2. Pullback Signal
- **Buy Pullback:** Price moves down to hit any line, then closes above the line
- **Sell Pullback:** Price moves up to hit any line, then closes below the line
- **Purpose:** Increases lot size when breakthrough occurs in same direction
- **Tracking:** Separate for buy and sell directions

### Order Management
- **Single Order:** Only one order at a time
- **Dynamic Lot Sizing:**
  - 0.01 lot (no pullback before breakthrough)
  - 0.02 lot (pullback occurred before breakthrough)
- **Stop Loss:** At Border Lines (Low Border for buys, High Border for sells)
- **Take Profit:** Target in USD (default $5)
- **Breakeven:** Move SL to entry at X points profit (default 100)
- **Trailing Stop:** Trail by X points after breakeven (default 100)
