Quote from MTE:
The sentence in the beginning of article under "Option terminology" doesn't make any sense at all:
"You buy an iron condor when you sell a call spread and a put spread"
How can two "sells" yield a "buy"!? If you do a trade for a net credit then it is a sell and NOT a buy!
Under that interpretation, sometimes a diagonal spread is a buy and sometimes it's a sell. That's not consistent.
If I buy Oct 80C and sell Sep 75C - this is either a buy or sell, depending on how you look at it. It's a buy because you own the further out month, as in a calendar spread.
Or, it's a sell, because you sold the lower strike call as in a vertical call spread.
But, whichever definition you choose, it has nothing to do with credit or debit.
from RichardRimes: That is Marks terminology which for those of us using TOS is confusing because we have both been taught and our platform is exactly as you say...when you are net short you are selling and when you are long you are buying on the TOS platform.
But Mark has been very consistent is the term "buying" IC rather than "selling"...I would be interested Mark in exactly why you call it buying as all the market makers and others that have worked in the pit call it "selling".
This a good point for discussion.
1) I now try to use verb 'trade' rather than buy or sell. It avoids confusion.
2) I was not aware that TOS, or other brokers, used 'sell.'
3) I use the terminology that my broker, InteractiveBrokers uses.
4) Here's why I believe that the way I use the terminology is correct, despite the obvious disagreement. [BTW, I got it wrong in my book. I use 'sell' throughout. But that was because I thought it was 'obvious' that sell is correct. I have since changed my mind.]
Consider a long condor position. I'm sure we all agree that when you have this positon, you BUY the condor;
Long Nov 35 call
Short Nov 40 call
Long the call spread
Long Nov 55 put
Short Nov 50 put.
long the put spread
You buy both spreads. You pay a debit. you own the condor. Just the same as buying the butterfly.
Now the question is, what makes this 'long?" Is it the fact that cash is paid? Probably. When we own a condor, we profit when the stock does not move outside the range.
Let's look at the 'iron' equivalent of this condor, also a position that profits when the stock does not move outside the (same) range.
Long Nov 35 put
Short Nov 40 put
Short the put spread
Long Nov 55 call
Short Nov 50 call
Short the call spread
It seems logical to me that if I am LONG the condor, and the <i>equivalent position</i> is an IRON condor, then I should be LONG the IRON condor as well.
Thus, to me the debate is:
Are we long the iron version because it has the same risk/reward parameter as the regular condor?
Or are we short the iron condor because equivalency doesn't matter. What matters is the fact that we sold two spreads and collected cash.
I vote for equivalency being more important.
But, I do see a point of controversy. Long a call spread is equivalent to being short the put spread. These are surely equivalent. So the argument becomes more subtle. It's okay for a long call spread to be equivalent to being short a put spread because the spreads have different names: put spread vs. call spread.
But because they are both condors (iron being an adjective, and not meant to represent a different spread) then long one is long the other.
I wonder who should make the final decision - but clarity on this point would be a good thing.
