Consider an ATMF straddle's price under lognormal and normal dynamics, and use the first central difference approximation
Question:
Consider an ATMF straddle's price under lognormal and normal dynamics, and use the first central difference approximation
\[N^{\prime}(x) \times x \approx N(x / 2)-N(-x / 2)\]
to relate the normalized volatility to lognormal volatility
\[\sigma_{N} \approx \sigma \times F\]
