I'm confused about what you're saying "works" for you...seems like you're just saying you "use charts"(?) Did you leave out part of your post / forget to quote something you meant to? I'm...not sure how well I'm following your candy analogy, but if you're suggesting that all of the MM bid/ask...

Yes, I didn't suggest it was a bargain of any kind -- hence my 2nd post where I say that I don't think teasing actually results in a better price than could be achieved without it...rather, all it seems to do is expose / give hints as to what a MM's 'best price' actually is. Yeah, that was my...

Makes sense, thanks. So you're saying that, in the example I gave for instance, the MM is just trying to be at the 'front of the queue' of $0.80 bids, in the hopes I ultimately decide to come up to that price level? I should mention also that as best I can tell, there's no actual transactional...

I notice this behavior all the time, so assume it's well-known and I just want to understand what I'm seeing / what's happening. Consider an option with a fair value of $0.60 whose current spread is showing as: 240 x $0.50 / 325 x $0.90 Now suppose I put in a bid of 10 x $0.55 (and no one else...

Thanks for the reply. I guess I don't understand the DTCC/CDS "depository" distinction...inasmuch as SHOP.C and SHOP.U are shares of the same company, aren't they altogether different share pools? I suppose I don't understand how 1 share of SHOP.C that I bought on the Canadian exchange "becomes"...

This Q didn't get any replies in the "Stocks" forum, so thought I'd try it here since posters may have a better grasp on the interlisted component, which I guess is FX-related: I have previously used the DLR / DLR.U pair to execute Norbert's gambit, but I have heard conflicting things about...

FYI after playing around with custom What-If scenarios in RN, and a fair amount of back and forth with IB, it appears that it's NOT possible to see potential margin impact of changes in the underlying prices, etc. A frustrating limitation, since it seems rather straight-forward...all RN will do...

Bump / anyone...?

I have previously used the DLR / DLR.U pair to execute Norbert's gambit, but I have heard conflicting things about whether it's possible to similarly journal equity stocks that are interlisted on both US and Canadian exchanges. Take Shopify, Inc., for example, which trades under symbol 'SHOP'...

Probably not, since I did get 1 of the 45 K's offered...so something was being dangled externally (though I suppose it's possible if you think 44 were cleared in-house, with the remaining 1 filled on the open market.) There were no flags associated with the execution (if what you're talking...

Odd behavior this morning that I want to better understand b/c suggests some sort of shenanigans: There was a standing offer of 45 contracts ("K's") @ $0.15, (which I believed to likely be a stale GTC order since the underlying had spiked up overnight) ~9:20am (premarket) I put in a Bid of 50 x...

Thanks for the link, but it seems like only 1 of the 2 products they offer would allow any sort of hypothetical / stress-testing / modeling. And that product costs $3,000. The free product only calculates margin requirements for a given portfolio...and IB's TWS software obviously already does...

I'm looking for a tool / resource that would let me model what various hypothetical movements in an underlying SP would do to my account's margin requirements. I have an Excel formula that calculates option margin requirements, BUT only for straightforward naked long/short puts and calls...my...

I've put on a trade involving securities denominated in both Canadian and U.S. dollars. In addition to the risk profiles of the underlying securities, the trade is also susceptible to exchange rate fluctuations: in this case, even if the underlyings move in my favor, any trading profits would...
