Maybe some kind soul will take pity. Assume a strike is points Implied volatility and Moneyness. Community Links Members List. Jun 16,4: Gentlemen, I'm having difficulty with this. But the underlying has shifted. Options, comparatively, we are looking at two different options aren't we? How can the shift in the underlying be reflected via an adjustment to the iv figure? I was thinking along the lines of perhaps incorporating the degree of moneyness moneyness unsure as to the correct method. Jun 17, Hi, Every time you record an implied vol, also record the delta of the option for which it is the vol. That way moneyness have a ready point of reference which factors in the strike and expiry time in the way that matters monyness. In your database you should juxtapose the two. When plotting moneyness vol surface you moneyness use vol on the y axis, delta on the x and time on the z. Strike is not so relevant as it moneyness the delta we are interested in really. In the OTC fx markets all fx options are quoted in terms of delta rather than strike for this reason. Jun 18,7: Originally Posted by grantx. Originally Posted by NotQuiteRandom.

Jun 18,9: Originally Posted by grantx View Options How can the shift in the options be reflected via an adjustment to the iv figure? Given that the implied vol is observed in the market place, why would you want to adjust it because the underlying has moved? Originally Posted by NotQuiteRandom View Post Every time you record an implied vol, also record the delta of the option for which it is the vol. You would, but a change in IV would then give the illusion of a change in moneyness when perhaps none actually happened. This moneyness change in probability is reflected in the change in delta as moneyness consequence of the vol spike. In turn, this relates to the degree of moneyness. Think of it like this, the spot market need not move for an effective change in moneyness where we qualify moneyness in terms of the options of the market reaching a certain point. The probability albeit only the market's perception of it has changed. Moneyness is only relevant as it relates to probability which, in this instance, is quantified in terms of implied vol rather than absolute number of points moneyness ATM. A 25 delta call is always comparable to a 25 delta call, regardless of strike, where spot is options or time. Jun 18, NQR, Thank you for the solution. I think the difficulty was due to the ambiguity of a half-baked and badly expressed thought — I was looking for a solution to an ill-stated problem. The reference to flat line on a chart was for illustration, not intent, ie iv flat, but underlying dynamic. Perhaps the question could be options as, What price moneyness? Moneyness-delta-probability — in this context I think any distinction is academic. I will return to this tomorrow when I have more time. Until then, thank you gentlemen. Jun 19, The next problem is recording the data consistently. Attached is a sample Excel file. From column C, I need to retrieve the iv corresponding to the delta in column E. Index, Match, VLOOKUP functions don't moneyness to work. To overcome the problem of matching precise figures column E with imprecise figures column B options, ie 0. Hopefully, this will work. Hi Grant Here is a solution. You CAN use VLOOKUP, but there are a couple of things you need to do to make it work. The reason it is moneyness working is that the number in column B is not actually a number - I think it is stored as text. So if you compare it to a table of numbers, it does not match. This can be fixed by using VALUE B3for example, in the VLOOKUP function. This will treat the contents of B3 as a valid number. Secondly, Options would recommend that you create a copy of columns E and F so that you can specify the values in E with 2 decimal places. This means that with VLOOKUP you can force it to look for an exact match. It is capable of returning the nearest value, but to do that I think the values have to be in ascending order, options you have them in options order. So, options H3, type the formula: ROUND E3,2 and copy down. This will enter moneyness E values into column H with exactly 2 dps. In I3, copy whatever values you need. Then, in another cell: VLOOKUP VALUE B3 ,H3: The FALSE will make it return an exact match. Hope this helps Rob. Thread Tools Show Printable Version. Search this Thread Advanced Search.
