## 3. Core Quantitative Formulas Used in Chart Replay

### 3.1 Position Sizing Formula
```
Lot Size = (Account Balance * Risk %) / (Stop Loss Distance in Pips * Pip Value per Standard Lot)
```
- **EURUSD / GBPUSD**: `1 Standard Lot = 100,000 units` (`~$10.00 per pip`).
- **XAUUSD (Spot Gold)**: `1 Standard Lot = 100 troy ounces` (`$1.00 per $0.01 tick`, `$10.00 per $0.10 pip`, `$100.00 per $1.00 move`).

### 3.2 R-Multiple Expectancy Formula
```
Expectancy (R) = (Win Rate * Average Win in R) - (Loss Rate * Average Loss in R)
```
Example: A strategy with a `42%` win rate and a `1:2.8` Risk-to-Reward ratio yields:
`E = (0.42 * 2.8) - (0.58 * 1.0) = 1.176 - 0.58 = +0.596R per trade`.

### 3.3 Profit Factor Formula
```
Profit Factor = Gross Profit / |Gross Loss|
```
