This would be my biggest concern, especially that the market is so good this year that no one seems to lose. Great start though. .
Hi guru, thanks for chiming in! And wow, you said a lot, most of which I'd like to respond to.
(Before I get started though, is there a way to see my replies directly below the post I'm replying to? I'm getting lost trying to keep up, and hoping that for you guys my replies show up right below yours."
I'm particularly glad you said this:
"I don’t see big issues with paper vs live, but there may be some. Mostly I would account for $0.10 potential slippage...
At least a few live trades would help you check the accuracy of your assumptions."
Have you made that switch, or comparison, between paper and live? (Has anyone here?)
I've been mindful of bid/ask spreads and try to stay away from really-wide ones, and I actually
have traded a lot of the same symbols in my real margin account (where I can't do SS's yet), mostly with PCSs, but also IC's, and the occasional Iron Butterfly. I haven't
directly compared BPs between the 2 platforms, but I've also done ICs and IBs in the 20∆ paper money account I don't track on my blog, and I can't say I've noticed any stark differences regarding fills or BP.
"...so many people showing off their huge profits from buying OTM options, that doing the opposite sounds nuts."
Thanks, I
think?! I don't know, but after a lot of reading, and I can no longer remember exactly where, but at some point the "insurance company" analogy clicked with me and I decided to pursue being on the selling side.
"You may have a bit of an edge by focusing on high-volatility, and diversifying among non-SPY correlated stocks that can move more randomly and won’t all lose 1000% on each position all at once. But it may happen."
My focus on high-vol was/is simply to find the option premiums that might make 1%/day possible. That was just a "that would be cool to do" dumb initial idea I had, but it's worked out so far and I'll stick with it for now
for these experiments.
When I transition to real money I'll likely trade off premium (and ROI) for lower-IV stocks. But you're right: they're definitely not correlated to SPY! Whether that's good or bad remains to be seen...
"We don't see many people using this strategy, possibly because they blew their accounts... At least you and anyone wanting to provide an opinion about your strategy should wait until you actually do experience very large drawdown, or at least until some crisis in the market. You will feel the heat at some point, and I hope you’ll feel it sooner than later, for your own sake."
GREAT observation, and that's EXACTLY what brought me here to start this Journal! I've found VERY little information on the web about trading Short Strangles, almost NONE about doing it way out at 10∆, and ZERO about anyone doing it
exclusively.
I started a blog which I haven't "advertised" yet, and thought I'd get some people at least wandering in accidentally, but haven't yet. I'm not ready to promote it yet, but I finally remembered the "Journals" section of ET forums, and I
knew that if wanted to get feedback/critiques/challenges about the strategy and/or implementation it would be here.
And so far I've NOT been disappointed!
So far I haven't had a drawdown of more than 10% in any of the iterations of the strategy, but I know that can and will occur. And you're right, I hope it happens while I'm practicing!
"Looking at probabilities doesn’t matter, as they’re only the current probabilities and based on as short historical period as the DTE of your options, not future probabilities."
I took the liberty of underlining 'current' and 'future' because I think that's what you were kind of saying:
current vs.
future probabilities
As a Mechanical Engineer by training with a smattering of statistics in college, and then later a Nuclear Engineer by vocation with a whole LOT of theory and real-life application of probabilities, I have to ask if I'm understanding you correctly here.
If we assume that Delta is a proxy for probability (or perhaps better, that ToS's Prob.ITM is an accurate measure of it), then would it be correct to say, "It's Monday and this XYZ $10 Call for Friday 4 days from now shows a 10% probability of being ITM by then. That means there's a 90% change it'll be OTM then,
as things stand right now."
Is that an accurate way of interpreting delta/probability
at the time of the trade? If not then I've got it ALL messed up! But if so, then I would say, "We have to start somewhere, right?" 90% PoP today is of course going to change by Friday as the stock moves around, but it feels like a comfortable place for me to start. Am I grossly out to lunch with that?
Thanks!
Mike
