    Hi all, I'm a newbie in options trading. I looked at Vertical Skew in OptionsVue and found that the Volatility is plotted against LN(S/K)/Sqrt(t). I was expecting the x axis to be Prices instead. Could anyone advise what LN(S/K)/Sqrt(t) is? Is this standard deviation around the current price ?

    That's moneyness normalized by time to expiration. It's a better way to measure if you want to compare across different underlying prices and different expiration dates. Here's more information if you're interested https://en.wikipedia.org/wiki/Moneyness
