|---|---|
| Notional Value | Total value of the underlying asset controlled |
| Margin | Collateral required to open/maintain position |

How Currency Derivatives (NSE, Global) Works
Mechanics
The mechanics of currency derivatives (nse, global) involve standardized contracts traded on exchanges with central clearing. Each contract specifies:
- Underlying asset and quantity (lot size)
- Expiration date and settlement method
- Strike price intervals (for options)
- Tick size and price quotation
- Trading hours and session times
Pricing Fundamentals
- Futures Pricing: Spot + Cost of Carry (interest – dividends)
- Options Pricing: Black-Scholes / Binomial models using Greeks
- Volatility Surface: IV across strikes and expiries
Practical Examples & Calculations
Example 1: Margin Calculation
Assume Nifty at 22,000, lot size 50:
- Contract Value = 22,000 × 50 = 11,00,000 INR
- SPAN Margin (12%) = 1,32,000 INR
- Exposure Margin (5%) = 55,000 INR
- Total Initial Margin = ~1,87,000 INR
Example 2: P&L Scenario
Long 1 lot Nifty Futures at 22,000:
- Nifty moves to 22,200: Profit = 200 × 50 = 10,000 INR
- Nifty moves to 21,800: Loss = 200 × 50 = 10,000 INR
- Daily MTM settled in cash
Example 3: Options Strategy Payoff
Bull Call Spread (Nifty 22,000/22,200):
- Buy 22,000 Call @ 150, Sell 22,200 Call @ 80
- Net Debit = 70 × 50 = 3,500 INR (max loss)
- Max Profit = (200 – 70) × 50 = 6,500 INR
- Breakeven = 22,000 + 70 = 22,070
Trading Strategies
Hedging Strategies
- Protective Put: Long stock + long put (insurance)
- Covered Call: Long stock + short call (income)
- Collar: Long stock + long put + short call (bounded risk/reward)
- Portfolio Hedge: Short index futures against equity portfolio
Speculative Strategies
- Directional Futures: Long/short based on trend
- Vertical Spreads: Bull/bear call/put spreads
- Volatility Strategies: Straddles, strangles, iron condors
- Calendar Spreads: Exploit time decay differentials
Arbitrage Strategies
- Cash-Futures Arbitrage: Exploit basis mispricing
- Index Arbitrage: Index futures vs constituent stocks
- Cross-Exchange Arbitrage: NSE vs BSE vs GIFT City
Risk Management

| Theta | Time decay | Collect premium (sell), avoid long near expiry |
| Vega | Volatility exposure | Buy when IV low, sell when IV high |
Margin Management
