How i can to figure out the volatility?

Quote from MTE:

There's no one best way of estimating volatility. You have to develop one yourself and in order to be able to develop it you need to read up on options (the books cvds16 recommended) to understand what is really going on in the market.

For one of my systems I do estimate volatility, but for obvious reasons I can't discuss it.
Okey....I start to read a Natenberg...Thank for all...I will find all answer for my question.....
 
Quote from cvds16:

I didn't calculate it like you think. But I played a different game than you want to play. I only needed an approximate future value to use for my option model. Say I saw the market was more or less pricing in volatility of 16 for all strikes in the front month. I then got my prices for all my strikes which I adjusted for skew, I did this a bit by feel. Say this gave me the following prices for three strikes: 3.51 / 2.29 / 1.43 I then would make a market like 3.40 - 3.60 / 2.20 - 2.40 / 1.35 - 1.55 for something like 20 lots (sometimes 50 on one side, if I was short options too big, I would be heavily bidding and only small offering) and waited untill I got hit. If I got hit I put the number of contracts into my option model which would give me my net deltaposition which I would immediately hedge and look at my overall risk making me to adjust my bids in puts or calls or bid or asks. The hedging was a continous thing.
I perfectly have understood you.....You trade as Market Maker or specialist...Did this stradegy get an enough money?
 
it was however quite labor intensive: I send about 1000 quotes each day, I traded DIA-options, so I used the ym-futures too as a hedging vehicle to reduce my margin. You have to be able to short the underlying. However it was not scaleable: doing about 300-350 options each day was the maximum feasible I believe the max I ever did was something like a small 400 options.
 
I think this good strategy......I will trying to do this on my market. But i think for this case you need an automatic trading system(robot) ...in another way you can't kiiled you demand in extrim market.
 
If you are getting hit on your bid or ask too much in too short a timespan you just cancel all your prices. I could do this with the touch of one hotkey. (I had several others programmed to quickly adapt the price/ammount of bid or offer) It often happened so I did this three or four times a day.
 
some good stuff here....in simplier terms you an use an option pricing model to solve for price by using a volatility forecast as an input, or use current prices to solve for implied volatility...
To me the question you have to ask yourself is if you can forecast volatility better than the competition....while I can trade price because I'm simply trying to jump on the back of the competition and not forecast things, I don't see how I can possibly expect to forecast volatility better in head to head competition with institutional quants...hence I don't trade options.
To me, knowing your place on the food chain is the biggest hurdle with trading when you are starting out.
Little fish in the ocean don't survive and prosper by trying to eat sharks.
 
I think your last remark is very true, I personally too think I have no value to add in predicting future value so I allmost don't use options anymore; excpetions to this rule is when I have a clear directional view and don't want to risk to much and want to use some leverage, but these are expectoins.
My real value was in making a market and trading relative pricing in series of the same month while hedging, I didn't really needed any clear view on vol for that, just be aware of the ebb and flow of the options and adjust my pricing accordingly. As I started to have cancellation costs of over 1000 USD a day, my profit-centre dissipeared from one day to another. I now trade intraday forex euro mainly, with some added eurostoxx and ym trades. It took me a long while to find something new ...
 
In an out-of-the-way market like yours Cowboy, I wonder if you could spread volatilities.

In other words, if you can buy the 120 calls for 18% implied volatility and sell the 121 calls at 19% implied volatility, and get delta neutral by selling the underlying, then try to undo that spread at even volatilities, you would make money.

In this case, you don't care about actual volatility of the underlying. You are simply trying to buy options cheap, sell them expensive, then undo the spread when they come back into line.

This is a somewhat sophisticated game but very profitable and very low-risk if such opportunities are available. What exactly is it that you are trading? Is it options on equities or futures? Maybe if you could post some detailed settlement (end of day) info it would be possible to identify opportunities.

hey would you mind expanding on that example further? im a bit new to options, but wouldnt you be up there a net seller of vol (calls) so you have to buy the underlying to delta hedge?

also on the side, why is the imp vol of a strangle the average of the two vols (of the call and put) ?
