[quote]Hi Rob,
well I will get straight to your question

to understand how the platform works just imagine you only and only would have a single position open at this given time.)
1. Margin calculation, or more estimation as I would call it is dependent on a few different parameters when selling options, therefore the margin of a sold option changes all the time and needs frequent monitoring if you are planning to consistantly hedge your positions.
the dependent factors are delta in the first line as this gives you the amount of your position at the current given time (if you go the same amount in the other direction on the spot market of what the delta is currently then you will remain delta neutral( on the Saxo platform you see it reflected on the margin utilisation area and it would show as 0 if you were fully hedged((will never happen

), (!!!by the way,it shows it converted in the currency your "account" is opened,very important to know,cause if you are trading the pound yen and your account is in USD, then dont be mislead if the calculations don't work out cause the value of delta will always show as USD in the margin utilization area)
or it would show you the full amount of the current delta if you were not hedged at all.
the gamma measure describes how the delta of the option changes when the underlying asset changes, that meaning the pips or price you see on the gamma figure will be added or subtracted from your current delta when the spot price is moving and therefore effecting the volatility.
Hence, the gamma also describes how much you would have to add or subtract from the delta each time the spot moves by 1% from current price and how much you should change your hedge accordingly to remain delta neutral when the spot moves.
Now if that is not to complicated then here is another one :What happens when the spot moves???:This variable is mainly concentrating around the "VALUE" of your position
Vega( a wannabe greek but never was and will be,it's a modern greek married into the greek society in a big fat greek wedding I guess!)
this one is probably the most unpredictable as it reflects the change of value of the current position(means how much is your option currently worth if you would exercise it at the current time) according to:
>how fast the market is moving,means how big are the swings in the market currently.
>where you currently are with your strike price compared to the spot(meaning are you at the money or far out, or far in the money
>how far your expiration date is.
>and how friendly the Saxobank helpline is, just joking eyyy...
these four factors will have an influence in how rapid your delta changes as the volatility is built in these factors, and when the markets go nuts like recently, that only means it is worth watching the delta carefully to take action when needed (all provided you really want to stay delta neutral for the sake of it which you don't have to always do really)in fact sometimes it is worth reevaluating where the market is currently going before you decide to further hedge or maybe wait a little longer.
O.K. where were we?
in conclusion it is not that easy to understand the whole complexity of the greeks but worth knowing the basics in my opinion and I just tried to give an overview and maybe somewhere out there somebody is reading this, but hey Rob if you open 10 standard contracts at a time then you should give me some advise,I only open small positions like a tenth of that at a time and play around with it until I beat and bleed the beast to give me some money.
Seriously I am happy to explain if any details should not be understood or if there is something else you ask in specific.
By the way thanks, I will check out what IKON has on offer regarding spreads and premiums,I think it's time for change.

Hi Alie,
Please forgive me for not respoding earlier, ti took some time for me to digest what you had written and my "day job" got a little busier than usual so I had to take a break from the markets.
Your explanation fo the greeks was very helpful to me..though I have been trading options (mainly in sotcks) for years, I never studied them in depth.
I did find some time to correlate the margin utilisation calculatios used by saxo when putting on option trades etc...my account is in USD and my trades were primarily usd/cad and eur/usd...i note that saxo has (at least in its demo version) provided a margin calcuation in the forex option trade panel that tells you exactly how much margin will be used in a pending maring transaction....
Did you have a chance to check out IKON at all?
As for my order size, it is NOT proporational to my sucess rate..lol...I only wish it was...what i try to do is sell some fairly out of the money calls on pairs that are in prounenced downtrends without getting shipsawed, yes, I know easier said than done..just looking for 1.5-2.% return per month on capital...sounds easy but the market has a way of putting me in my place..
