I'll separate the rocket science into a different thread later on. Missus has me doing some confounded chores for the moment

happytrader said:Any beginner reading this thread for education purposes might actually get the idea that one has to be extremely intelligent to trade options successfully. However, the most successful traders I know personally get to the point where they only trade up to a handful of stocks or patterns continuously and at key times. Decisions and trades are made and executed rapidly. From my own experiences and observations of colleagues, limited selection, key times and quick decisions seem to be defining characteristics.

Agreed.
To progress the model we need to;
*ask enzo to reconstruct the initial valuation model [with amended vega]
*or, take a new, real time example, and provide a dual analysis & valuation.
If option #2 is undertaken, we will need an example that includes a non-linear event that will provide a similar scenario for valuation as the previous litigation in the FRX example.
Anyone interested?

I'm not sure we could reconstruct the FRX trade faithfully without live data. Also, as the result is now known, surely this would taint said reconstruction.
I will try to find a new scenario... so what we want is some pending unknown known. e.g. litigation, FDA announcement or similar, right? This is what will give us the enourmous IVs and time skews we are looking for.

I don't know or have ever known of any trader that actually uses these models to trade. Many do however, take a peak at the days trade history of a particular option and most definitely assess open interest. The usual method is actually to identify a key time, make a trading decision and commit to an entry. This is made by several methods:
1. make an offer at the last price (might get a bargain)
2. make an offer halfway between the spread (high chance of success)
3. buy at market (entry assured)
Models are all very good for theoretical pricing but things can move very quickly and the pricings can be way off the mark. This is after all an auction and the market is always right.
Also there is absolutely no reason why you can't get accurate pricing by free trialling option software and using the above methods to test your models. In fact thats how we of the same school and teacher were all taught to paper trade for a period of 6 weeks on low volatility stocks.

As to tainting, or biasing, the result, certainly, but this of course is a problem with analysis in hindsight unless allowed for. However as an initial experiment, it has certain characteristics that are helpful when building a new model.
Irrespective, in essence as to what we are looking for.......correct.
We want a trade that the greeks have priced as attractive for strategy XYZ
But that has a;
*known event
*unknown timeframe
*unknown magnitude
*unknown result
These, [and possibly some I haven't thought of] types of risk are not accurately, or even adequately priced via the greeks.
I am looking for a quick, easy, methodology, to use as a pricing mechanism as a cross-check on the price generated via the greeks.
I would hazard a guess that 99% of options traders on this site utilize an online calculator, or software to do the calculations in a Black/Scholes, or Cox/Rubenstein calculation.
Nothing wrong with that after you have done them long-hand for a year or so as you will then fully understand your greeks, and you will notice that certain elements of risk are ignored, or not built into the models [in specific scenarios].

Yes, this will work just fine.
Does your modelling, or whatever methodology you employ, provide a value or price? [if so make a note of it, and the two values can be compared later]
Possibly Magdoran & Sails might calculate their price or value, and we would have further values as a comparison.
We know happy's value, I've just removed the dart from the value selected.

Magdoran said:Hello Ducati and Wayne,
Can I ask a dumb question here? What exactly are we trying to do here?
Hopeful said:RIG (a US stock) is currently trading at 70.45 , Oct calls with a 75 strike are selling for 1.90. So then I hit the bid and short the call then go buy the stock. If it goes down to 70.45 minus 1.90 = 68.55 then I exit with a small loss (brokerage). On the other hand if it ends up anywhere above 68.55 at expiry then I'm laughing (yes, American style means I can get assigned...).
