Today seems a record for my adding confusion to things. I think this is number three for today.
For this discussion's purposes and the account I report on, I only do credit spreads and form Iron Condors where possible by selling another spread. Each spread is managed separately. The attraction of forming an Iron Condor, of course, is the second spread sold requires no additional margin so you get an additional profit with no additional funds and a small increase in risk.
Now, if the market stays sideways, the two spreads expire calmly and I keep the credit received which yields between 10% and 12% for the 60 day life left in the series. If the market trends, however, the spread farthest from the underlying instrument price will reach its maximum profit with lots of time left. I buy it back and form a new spread closer to the underlying instrument price. I have had this happen up to three times in the short time I have been trading in this account. That's four spreads on that side averaging 6% each. That's 24% for the Iron Condor life.
What about the other spread which is likely in loss territory for most of its life? So far, I have closed them for small losses (less than 5% of funds at risk). So an Iron Condor that was set up to yield 10% to 12% ends up yielding 19% or more. I set my bail limit at 20% but that has mostly to do with stomach acid production than any testing. Setting it at 20% means that because I bail "at the market" I might loose as much as 30%. So a failure requiring a bail out ends up leaving me somewhere between a 4% net profit to a 9% loss for the Iron Condor. That's a rough landing I can walk away from and be ready to fly again.
Any clearer, or have I muddied things even more?
Well, hold yer horsies... What you're describing as the iron condor strategy is an entirely different matter and smth that might actually be very interesting (and, I suspect, if we find the elusive H'Edge, it's gonna be in the iron condors).
What I am trying to understand is the simpler "credit spread" strategy, which is the starting point, right? So let's decompose what you're doing into two parts:
Strategy 1: Credit spreads
Strategy 2: Credit spreads w/subsequent legging into "cheep as cheeps" iron condors, mkt conditions permitting.
By default, assuming the worst case where the right mkt conditions never actually occur, you end up running Strategy 1. Otherwise, you end up running Strategy 2. Let's say edge (or Sharpe or however you choose to define it) for Strategy 1 is HE1 (stands for Howard's Edge 1), while for Strategy 2 it's HE2. Therefore,
H'Edge = (1-P) * HE1 + P * HE2,
where P is the probability that the right mkt conditions do come along.
Therefore, to figure out what your total edge is we have to know HE1, HE2 and P. The point I was trying to make is that I am pretty sure that HE1 is, at best, 0, but more likely negative. Can you estimate P, based on your experience so far? An example trade would be nice, although, since I am not an equity guy, you'll have to be a bit more explicit with the strikes, etc.
All this, obviously, if you're willing...
