Introduction
Margin calculation is a critical aspect of trading futures and options, impacting your leverage, risk exposure, and trading strategies. This guide explores how margins are calculated across different scenarios, including near-month, mid-month, and far-month contracts, as well as various trade types.
Key Factors Affecting Margin Calculation
Contract Expiry:
Margins vary based on whether the contract is:- Near-month (closest expiry)
- Mid-month
- Far-month (distant expiry)
- Stock Volatility:
Highly volatile stocks require higher margins due to increased risk. Trade Type:
- Normal Trade: Full margins apply.
- Intraday (MIS) Trade: Lower margins but must be closed the same day.
- Cover Order: Requires a predefined stop-loss, offering the highest leverage.
