Somewhere back there I recall saying something like "let's keep the thread title about selling options, rather than BPS as a specific technique" because, you know, in a year the BPS might be so last year.
I wasn't actually thinking that in a few days, BPS might be so yesterday
God I love this thread and the different ideas and insights that come along. I don't know about the DITM call debit spreads yet, but I've learned enough in a few posts that I'm going to try a test position out this week. This is my own decision and I'll experience my own consequence
I've got some other put credit spreads that I am hoping to enter. If I do get my entry on those then I'll just take some of the money that would have been directed into a put reserve (retirement account) and use it to make the purchase in the call spread. I am particularly interested to see what the position looks like in the position view. Is it equally easy to see progress towards max profit?
Are there difference in how margin gets handled?
My guess is that the purchase dynamic means that there is no comparable 'free' (margin) position on the other side of the share price as there is with an Iron Condor. Then again I don't make use of that very often (actually once, ever, so far) so losing access to the 'free' call credit spread isn't exactly crimping my style.
My first pass guess at which is better is to look at IV. I'd guess that whichever IV is higher is the better side to be buying / selling, with a bias towards the put side if one is also pairing it up with the call spread.
A random thought that's occurred to me is that with these having such similar behavior, I wonder if there's an arbitrage opportunity here. I.e. aggressive selling of put credit spreads pushes down their IV relative to the calls, enabling the deep pocket and high speed traders to buy the call side at a premium to the put side.
I wonder if the market makers have been perfectly content with their current pocket picking setup
I could easily be reading more into this than I think, and I'm currently in that early flush of OMG-what-a-cool idea like I had back when I started to grok the power of the put credit spread.
We might need new shorthand terminology, because DITM call debit spread, or maybe bCS vs. BCS / BPS vs bPS or something will be needed. *sigh*
