Here's another one of those stocks that people are dying to short, leading to huge put/call arb numbers: NAT, trading $36.50 June 35 call: $2.20 June 35 put: $3.20 Borrowing costs as per IB: 50.25%.

Christ man, get a hobby. And a sense of humor.

Why would I care about volume? The ask/bid spread is more a concern... but anything that's positive, even if it's just a couple percentage points, helps. I'm carrying $1.2m on the long stock side of things this month. Even if I made myself just 5% annualized by going with the EFP -> SSF...

Wait, that just clicked for me. Why *am* I shorting shares, as long as IB has very convenient SSF/EFP support built-in? Anyone know whether there is SSF/EFP support via the API...?

The highest I've seen was at -35% or so. I don't think I've seen anything higher than that, although I know there was discussion of SHLD earlier this year. I would kill for an automated tool that I could use to update my spreadsheet every night, that didn't require me to log in. Sooner...

Charging up the butt is a concise, highly technical phrase referring to the 30%+ rate I'm currently paying for a short position. As far as your guarantee that I didn't know that I couldn't do those kind of shorts... what's your interpretation of this sentence from my original post? <i>...

Didn't your momma ever teach you that if you have nothing nice to say, don't say anything at all? No whining here. If I didn't like IB's policies, I'd be trading elsewhere. If you have anything useful to add, feel free to share.

Hi, I've been trading long-only strategies with IB for months, and am now diversifying into a short strategy. It's a little scary dealing with the extra "power" that IB gives you, in terms of giving you more choices in terms of shortable stocks... but also charging you up the butt in...

Thanks, I'll put that in the toolbox. For now, I figured out some of the other data I'm downloading gives me the exchange for each symbol. I get implied vol data (50 symbols at a time) using ivolatility.com, and they conveniently attach the exchange to each symbol. So that's even...

Hi, Is there a quick way (in excel or other similar platform) for automatically figuring out what US exchange a particular symbol is trading on? I have a list of 160+ stocks, and I need to specify the exchange for each. Obviously I could just look at each symbol by hand, but would...

On ERTS though, you really didn't see a "surge" in IVM leading up to earnings. I use the ivolatility numbers for looking at this. A month ago, 30-day "IV Index" was 68.21%. A week ago, 30-day was almost constant at 65.22%. Today, it dropped to 50.08%. So, that's a really significant...

If the premium didn't drop while we got closer to expiration, I would define that as IV increasing. It seems like you're alternatively interpreting the event as investors putting on a spread early and just "holding the price"... not really sure I understand that view.

Not many folks interested in this topic? Unfortunately, CBOE has killed off RUH... temporarily or permanently, unclear as of yet. I'm guessing that with the huge spike in volatility in Sept/Oct of last year, whoever was going to make a market and sell these things realized they couldn't...

You know, I do recognize my situation is a little different from most. I'm really trying to squeeze blood out of a stone with my trades. I'm working with ATM options, and only expecting to make ~0.20 per contract on average, and that's why I take so many positions. That's why the extra...

Mark, I respect your experience, and I also don't for a second believe my strategy is "dominant" or superior (in the academic sense). So, don't take this as me trying to change your mind. But I will say: your comment about the profits being "your money" is exactly the market psychology...

Does anyone have practical experience, whether other types of bars (like volume bars) addresses this kind of problem? Anyone aware of any data providers that provide volume bars?

I'm more on your side than the other guy's side. I don't think commission cost is as big deal for me as the ask/bid spread. The OTM options don't exactly have a lot of volume... no one will ever hit you if you sit on the ask/bid, so you're giving up 0.05-0.1 a contract right there.

I personally think any financial is a little scary right now, from the point of view of stress test results due Thursday. The 10 day expiration really equals an eternity to expiration, with that still on the horizon.

I've given this issue some serious consideration... and although I'm not convinced I know "the" answer (seems like others on this thread have already got the patent on "the" answer)... I know how I'm strongly leaning at this point. Just by way of context: I write about 800-1000 front-month...

I've asked a similar question in the past. Once you filter past the bravado and look at the realistic responses from people who've been in the field for some time... ... it looks like we should all accept we're human, and accept normal market results. 20% a year *consistently* is an...
