Important Limitations
These calculators are educational tools based on theoretical models (Black-Scholes). They do not account for:
- • Transaction costs, commissions, or fees
- • Bid-ask spreads or liquidity constraints
- • Early assignment risk for short options
- • Changes in implied volatility (except Vega estimates)
- • Dividend payments or corporate actions
- • Real-time market data (you must input current prices)
Always verify calculations and understand the risks before trading. Past performance and theoretical calculations do not guarantee future results.
