Quote from RichardRimes:
I was going to add to my post that I thought your ratio spreads should be doing well in this market. I think last weeks big moves WERE definitely exacerbated by the So Gen debacle.
I've been thinking about doing them but not sure exactly how to ratio it out. Not to diverge too far off topic but do you have a defined ratio depending on the deltas your looking for? or do you usually just do 2/1...3/1 etc. thanks D
Not off topic at all as I've learned heaps from the replies on calendars.
In a nutshell, I do 1x2 ratios on ES. They are 50 point wide and i've only been doing PUTS. Before doing 50 pt puts, I traded christmas trees which were endorsed by Mav, but I feel my 50 wide ratios are even safer.
eg. Buy 1 1300MAR PUT
Sell 2 1250MAR PUT
I might receive $6 credit for opening the spread.
The beauty with ratios spreads is that it starts off -ve gamma but can end up +ve gamma if time decay is sufficient.
Have been closing my 50 pt ES spreads every month for credit except for my FEB and MAR spreads thanks to last week

Got hit there and lost some money.
Sometimes you can even close it for more credit than you received to open them. Bear in mind this only happens if you have SUFFICIENT TIME DECAY. If my spreads are close to expiry, i actually want the underlying to fall towards my strikes.
With credit verticals, unfortunately it always remain -ve gamma. I guess the trade off is that the ratios have the risk of naked PUTS...
Im still testing and plan to do some 60pt wide ratios for even more safety.
Pls don't take my advice as im only a newbie and trade from learning from others and filtering to see what works for me. Feel free to ask more qs but Im now off to sleep soon in AUS.
