# Forex Trading — Asset Class Reference

## Major Pairs & Characteristics
| Pair | Nickname | Spread (avg) | Best Session | Volatility |
|------|----------|--------------|--------------|------------|
| EURUSD | Fiber | 0.1–0.6 pips | London/NY overlap | Medium |
| GBPUSD | Cable | 0.3–1.0 pips | London open | High |
| USDJPY | Ninja | 0.2–0.7 pips | Tokyo/London | Medium |
| AUDUSD | Aussie | 0.2–0.8 pips | Sydney/London | Medium |
| USDCAD | Loonie | 0.3–1.0 pips | NY session | Medium |
| USDCHF | Swissie | 0.3–1.0 pips | London/NY | Medium |

## Pip Value Calculator
```python
def pip_value(pair: str, lot_size: float, account_currency: str = "USD") -> float:
    """Standard pip values for 1 standard lot (100,000 units)."""
    pip_sizes = {
        "EURUSD": 0.0001, "GBPUSD": 0.0001, "AUDUSD": 0.0001,
        "USDCAD": 0.0001, "USDCHF": 0.0001, "USDJPY": 0.01,
        "XAUUSD": 0.01,   "XAGUSD": 0.001,
    }
    pip = pip_sizes.get(pair.upper(), 0.0001)
    # For USD-quoted pairs: pip_value = pip * lot_size * contract_size
    return pip * lot_size * 100_000
```

## Session Hours & Liquidity Windows
| Session | UTC Open | UTC Close | Key Pairs |
|---------|----------|-----------|-----------|
| Sydney | 22:00 | 07:00 | AUDUSD, NZDUSD |
| Tokyo | 00:00 | 09:00 | USDJPY, AUDJPY |
| London | 07:00 | 16:00 | GBPUSD, EURUSD |
| New York | 12:00 | 21:00 | All majors |
| **London/NY Overlap** | **12:00** | **16:00** | **Highest volume — best for scalping** |

## Carry Trade Framework
```python
def carry_trade_screen(pairs: list, rates: dict) -> list:
    """Find best carry pairs: borrow low-rate currency, invest high-rate."""
    results = []
    for pair in pairs:
        base, quote = pair[:3], pair[3:]
        carry = rates.get(base, 0) - rates.get(quote, 0)
        results.append({"pair": pair, "carry_pct": round(carry, 2),
                        "direction": "LONG" if carry > 0 else "SHORT"})
    return sorted(results, key=lambda x: abs(x["carry_pct"]), reverse=True)
```

## Key Forex Risks
- **Central bank risk**: Unexpected rate decisions cause 100+ pip moves
- **Economic data risk**: NFP, CPI, GDP — trade around releases with caution
- **Correlation risk**: EURUSD and GBPUSD often move together — don't double up
- **Swap/rollover**: Holding past 22:00 UTC server time incurs overnight swap fees

## Exness MT5 Pip Sizes (your broker)
```python
PIP_SIZES = {
    "EURUSDm": 0.0001, "GBPUSDm": 0.0001, "USDJPYm": 0.01,
    "AUDUSDm": 0.0001, "USDCADm": 0.0001, "USDCHFm": 0.0001,
    "XAUUSDm": 0.1,    "XAGUSDm": 0.01,
}
```
