How the Structure Works
Positive Theta decay (+θ) erodes the call option value daily. You profit from time passing and volatility contracting.
Selling a naked Call is a pure credit strategy where you take the other side of retail call buyers. You make money if the market falls, moves sideways, or rises slightly without breaching your strike. However, because upside market moves can theoretically be unlimited, naked calls carry extreme undefined risk.
