Quote from IV_Trader:
does Hoadly has position's analyzer ? Can one use diff vols for diff month for what ifs ?
Seems he canât do it.
You can start any combo by setting your overall volatility, calculate theoretical prices, view your P/L graph and then adjust vol to see the graph change.
OR:
you can start with real prices, calculate their respective IVâs, and here it comes: then examine future P/L/ graphs based on adjusting ONE overall volatility. (Compare: you can adjust each legâs strike separately, but not its vol.)
As I wrote earlier: I just donât see how this is done. So one leg today has IV 120, another has 80, and then we examine future P/L based on vol 90. How would the program handle this? Do all IVâs suddenly agree on 90 as from tomorrow? Lineary approach 90 toward expiration?
Does anyone know? How can you sensibly analyze especially a calendar if you canât set different IVâs?
basis perhaps? Youâre a 12-year pro, Iâm a 3-year amateur. No tease, Iâm seriously interested and perhaps missing the obvious.
Note:
I still didnât buy it, IV_Traderâs remark held me back.
