Thanks for the reply; do you have a source on this? It seemed like a reasonable assumption, but it's not really clear that an expiration is functionally the same as a closing trade; the latter has an explicit T+1 settlement period (settlement required because instruments are ostensibly being...

Not sure how many traders of Canadian options there are here, but my understanding is that for US taxpayers, any trades made on Dec 31st still count towards the 2021 tax year. However, Canada does it differently: December 29, 2021 – Last trade date for 2021 Tax Gain/Loss Reporting for Canadian...

FWIW they've fixed it now.

Not clear what you mean. Bug described in detail in the OP. Anyone could check this for themselves in 60-seconds in TWS...just trying to understand if they're seeing it too.

Can anyone check this out, perhaps? Want to know if it's affecting people other than me...just open the Event Calendar in TWS and see if any of your Portfolio companies are shown in the Calendar boxes (with a blue dot next to them, per the legend on the left). With Earnings season approaching, I...

Is the red/blue color-coding in TWS Event Calendar broken for everyone? This seems to have just happened in the last couple weeks. When I select "Portfolio Companies" and "Corporate Earnings", it's supposed to show blue dots in the calendar for the Earnings dates for the companies I hold in my...

Sure...though the inverse is equally true: if no one ever crossed a spread, there would be no volume either. This makes sense. As I wrote, I'm sure folks much smarter than me have run the numbers on what will generate the most volume / price discovery and they settled on this instead of the...

My understanding is that for exchanges that offer liquidity rebates, it's always the MAKER who gets the rebate rather than the TAKER, correct? E.g.: - XYZ best quotes showing as: $0.50 / $0.60 - I post Buy 10 x $0.55 (midpoint), I'm the Maker (creating potential liquidity) - Someone crosses the...

Seeing this thread late, but TD is a trainwreck. Dangerous, even. Like you, I've observed horrendous performance in the first hour of the trading day. It's their back end that's the problem, not Advanced Dashboard (you'll have the same issues via their web-based WebBroker). I've talked to a half...

No, I own Calls on the Canadian/TSX listing (AUP). That's what's getting delisted.

I own a bunch of Aug Calls of Aurinia Pharma (TSX: AUP, NASDAQ: AUPH), which is voluntarily delisting from the TSX on 7/30, but keeping its US listing on NASDAQ (b/c 95% of the volume is on the US side). They're OTM now but not by much. Presumably I could track whether they're "ITM" by...

I have, and I'm reading more. You write as if I'm trying to beat algos at their own game. I'm not. Doesn't mean there isn't a way to optimize my own order submission to give myself the best shot at getting / retaining queue priority.

I'd be grateful to hear how I can solve it, since I don't think I'm any closer to doing so, despite having read all the replies ITT. Question remains the same: what routing options I should use to give myself the shot at first-in-queue priority at a given midpoint (again: if I'm fee-insensitive...

Whenever I submit an order at the midpoint (Sell order @ $0.10 in my OP example) on less liquid contracts, I'm rarely filled immediately...typically my order sits there as more $0.10 Sells accumulate...I made a previous post complaining that even though I was the first to submit a $0.10 Sell...

I'm still trying to wrap my head around IB's various SMART / direct routing choices; my initial attempts to play around have been oddly expensive; have gotten some $1.75 / contract fees (typically hadn't seen anything > $1.25)...guessing it's b/c of IB's $1.00 fee for direct routing coupled with...

Damn, life got interrupted so I'm only now getting back to my thread to post replies. Hopefully there are still interested responders. There seem to be 3 categories of US options: Ones that ONLY trade in increments of $0.05, and you're not even able to enter a non-nickel price (in IB at...

IB's SMART-routing sends orders to...well, any number of a half-different exchanges. And unless I'm mistaken, my order can actually be skipped around to a bunch of different exchange; i.e. when it's in "green" / active status, I can mouse-over the order to see which ECN it's live at...and it...

A typical presentation of this annoyance: Bid/Offer for a contract is 70 x $0.20 / 85 x $0.30. I submit a Sell order for 50 x $0.25. I'm the first Offer at $0.25, but others also submit Sell orders @ $0.25; I don't get filled right away and spread appears as: 70 x $0.20 / 125 x $0.25. I then...

Yes, there are certainly other headwinds for crypto, but none of this is really responsive to the question I posed in the OP, which was specifically about whether traditional market-making processes will port seamlessly to the crypto environment. Thanks for keeping this thread somewhat on...

Market-making 101: MM writes a Call, then goes out and buys a hedging amount of the underlying (and adjusts position over time to remain delta-neutral.) It's worked just fine for decades, but I've been wondering lately whether those traditional mechanics will map as neatly onto the crypto...
