Yes, something like that - and it had to be cheap. It does need strong moves to work well. I'm not completely convinced it is a good way to go, but it was fun trying it out. Certainly way too expensive in the Oz market with fees. It's not a set and forget as one needs to be watching to make adjustments.
Have you ever come across skip striking the flies to have yet another configuration of the "M" spread (hehe)
e.g. 170/175/180 put fly --- +2/-3/+1
180/185/190 call fly --- +1/-3/+2
The characteristics are like that of a condor.
as does optionsoracle. Not as good as hoadleys, but a free modeller nevertheless.Cutz
I have software that accepts numerous legs and products. But the software is catered towards other markets.
I think Hoadley has the Open Positions module that lets you enter numerous legs.
Great stuff Grinder, many thanks.
Can you please explain a little more on "adjust into different sepcies"? Are you referring to different strategies, different underlyings, something else?
Thanks
Thanks for sharing your management of that position with us!!!
I especially like the bit about selling the flies in between when the market is tanking.
I have been running a few simulations of it and I seem to be getting a negative vega, positive theta creature which is fairly delta neutral at the start. The position I suggested above seems to favour drops in IVAll of which is the opposite of what you have described LOL
The only thing that seems to reconcile is that skew to the downside is favourable
I think I am looking at a different configuration to yours!!

Hey Cutz,
Just back for Easter
E.g. 170/175/185/190 Condor
Assume 5pt strike increments
Code:Strikes 170 175 180 185 190 +1 -2 +1 Butterfly 1: 170/175/180 +1 -2 +1 Butterfly 2: 175/180/185 +1 -2 +1 Butterfly 3: 180/185/190 +1 -1 0 -1 +1 Total: Add down = 110/115/125/130 Condor
Butterflies have maximum profit at middle strikes/apex with very little time to expiration
If the prices are attractive enough, you could sell off a butterfly and take money off the table/lock in profits
E.g. hits XYZ $175 sell off the 170/175/180 fly
XYZ could tank from here, but you have reduced the loss/or book a small profit
If it moves back up to $180, you could sell off the 175/180/185 fly
In hindsight it would be better to leave the condor untouched if it comes back into the 180 range
Just another way to manage
Hi Gary,
I'll leave that to the experts as i've never put on a butterfly (yet) but personally a more attractive range of strikes would be a few levels down, i think you may also have to consider market outlook and it seems like we're long overdue for a correction. (Note;personal opinion only i'm more than likely to be wrong).
Which leads me to another question, you guys that put on flys, do you consider market outlook or are strikes set based on IV and probability of loss zones touched based on standard distribution the day the position is put on ?
thanks guys for all your replies
i am currently reading in cottles book about the structure of butterflys and carding them up but sometimes takes a few readings before it starts to make sense
Michael Catolico is one of the contributors and is an ex US market maker. His mock trades are interesting to follow, but due to the number of adjustments - hopeless for the Oz market.
I have also traded some diagonals and long line, multi strike calendars with extra wings. These type of calendars work wonders if IV rises a bit, but easy to lose money quickly if IV falls.
Diagonals are an interesting set-up. I did quite a large one of these in the first twelve months or so of my option trading on NCP now (NWS). Put it on just before Murdoch decided to take the company to the US. It rocketed upBeing so new at it, I decided to close out - it was Thursday morning before the Easter weekend and the MMs obviously sensed I was a bit desperate so didn't get a good fill on the exit. Anyway, followed the trade through with "what-ifs" and actually found that if I had kept rolling the short call up and out, the position would have still returned a profit. But then with the frenzy of the move, I think IV would have remained farily high which would have helped as well. Didn't understand much about the greeks at that stage!
Ah yes Mr Catolico, I have read his posts - particularly about the good, bad and ugly trader LOL
I find diagonals when I have no spot bias, better ATM
The back month takes advantage of accumulation in gamma (speed) and long vol, while front can be shorted ATM gamma and shifted like in your example.
Eek at aussie MM's - man they are a tough lot
EDIT: Delayed responses I know
lol - some mixed messages there about Mr Catolico. Not sure exactly what you mean.
I think he said he took on way too much risk at one stage as an MM and apparently took a pretty big hit. I have appreciated his sharing his knowledge so freely and seems to take pretty good care of risk in his trading - or at least last time I looked. Haven't read any of his posts for a long time now.
Hi Sails,As expiry approaches s begin to collapse in OTMs,
Hi Sails,
Can I ask what "s" means, when you say "s begin to collapse in OTMs"?
Thanks,
Fox.
