    Any data providers (other than IB) offer real-time estimated/model option prices?

    I'm a little confused by the reply, but in the case of less liquid options with wide spreads (or sometimes no displayed Bid Price or Ask Price at all), IB still calculates what I guess is more accurately described as the theoretical price (not sure if they're using Black Scholes or what; they...

    Any data providers (other than IB) offer real-time estimated/model option prices?

    IB's Option Model Price tick value ("ModelOptPrice") has always been buggy: it often doesn't populate properly (in TWS, or in Excel via API), and moreover can be wildly inaccurate early in the trading day. I'm looking for alternatives -- do any other brokerages or data providers offer a...

    Most recent "Beta" build of TWS flagged as malware. Anyone else?

    Don't think any prior version of TWS -- any of Stable, Latest, or Beta -- has ever had problems, but the most recent BETA build (979.4m) is being flagged by Avast with the following IDP.Generic message: I usually don't worry too much about this kind of behavior and create a manual exception...

    Any real reasons left to go with a desktop / tower over a laptop? (Faster / more powerful perhaps?)

    Hm, might have to amend this: I sat back down yesterday (after ~2 months of using this NUC without issue) to find that the machine had apparently rebooted on its own, and there was a black screen like the below saying "System has recovered from an over-temperature condition." Quick google...

    IB trader workstation worth learning ? or piece of junk ?

    Only speaking for myself here, but I've used Classic for 4+ years -- every time I try Mosaic (usually because some demo video I watch is showing things in Mosaic and I want to follow along), I run scurrying back to Classic because it feels so much more intuitive to me. I know of no feature (for...

    Recs for tools / services that track correlation in movement between stocks?

    Haven't done much in the field of correlation between different symbols and want to know what tools or services might give me a good primer on how to identify peer companies whose movements another stock is, to some degree, correlated with. FWIW, I'm asking for a specific purpose: I'm looking...

    IB trader workstation worth learning ? or piece of junk ?

    If you're even asking this question -- or at least asking it in this way -- I'm going to go ahead and say that it's probably not worth your time. (That's not meant as snark, but rather genuine advice that I hope saves you some time.) Or let me put it another way: you're probably not the type of...

    Trading the Open -- are there tools or resources specifically for that?

    Yes, I understand that the pre-open is incredibly noisy, and that trying to discern a reliable signal in the noise may be chasing ghosts -- not quite ready to dismiss it as entirely useless, though. There are still data points that range from quite reliable, to nearly meaningless, e.g -...

    Distribution event (Sym: BIP) - anyone help interpret this?

    I own a handful of Brookfield Infrastructure Partners (BIP) Calls and Puts - some ITM some not. There's a corporate action that I'm having trouble wrapping my mind around (link to OCC press release; pasted image of relevant part below.) Cliff's: Trying to understand what this means, if...

    Relative orders that move both ways?

    The one rationale that seemed to be offered most frequently (IIRC) was that REL orders that backed off (when the next-closest-bid backed off) would create exponentially more order volume, since there'd need to be a constant monitoring of the entire L2 order book to maintain a bid that were $0.01...

    Relative orders that move both ways?

    No, this does not exist. I went deep down the REL order-type rabbit hole and nearly made a thread about it last week...still might. You can search for old (very old) threads on ET (like 8+ years ago) where people were complaining about exactly this, with others offering reasons why IB doesn't...

    Trading the Open -- are there tools or resources specifically for that?

    I'll try the revolver and report back. I guess from these replies there aren't many tools or services optimized specifically for the open...? I'm willing to self-educate if anyone wants to point me in the right direction re: articles, services, etc. As mentioned in the OP, what I'd really like...

    Any real reasons left to go with a desktop / tower over a laptop? (Faster / more powerful perhaps?)

    FWIW after reading about the Intel NUC's ITT, I actually bought one of the higher-end models (i7-10710U / 64GB ram). My previous setup sounds like it was similar to yours: high-end gaming laptop w/ 32GB running 2-3 external monitors...wanted to know what I was missing by having 32 instead of...

    Trading the Open -- are there tools or resources specifically for that?

    Posted this in trading software forum, but didn't realize how low-traffic that forum is compared to here...I'm looking for any online tools or resources that were perhaps created or optimized for the chaotic window leading up to the 9:30 open. I know that's a broad Q, but I'm not even sure...

    IB's charts suck -- any recs for better intraday charting sites or software?

    Thanks for replies ITT so far. For those of you who have made specific mention of an IB connection (to the 3rd-party charting service), can you help me understand just what this means? In what respect is the charting "connected to" my IB account or IB data feed, and what does that 'connection'...

    IB's charts suck -- any recs for better intraday charting sites or software?

    I'm giving up on IB's for intraday monitoring; they crash a ton and have annoying functionality limitations*. Is there a consensus best charting program or site? Paid (reasonable fee) would be OK if good value. (*For ex: IB forces the same color coding on multiple charts; e.g. if you have...

    Tools and resources to trade the open?

    I'm looking for any online tools or resources that were perhaps created or optimized for the chaotic window leading up to the 9:30 open. I know that's a broad Q, but I'm not even sure what's out there. One thing that would be beneficial: zeroing in on where the first trade(s) are going to come...

    That's a first... IB notified me that one of my trades is being busted.

    Had it happen a few times. What's incredibly aggravating is: There's no transaction for the bust/reversal shown in the Trade Log window. Sometimes there's a flash popup window alerting you of the bust, but one time I didn't get one, and was only able to piece together what happened when I saw...

    Why does clicking the Bid/Ask sometimes create an order row but other times an order ticket window?

    This oddity has bothered me for ages, so hopefully someone can just put it to bed for me: clicking the Bid or Ask price on a ticker row in TWS during market hours always creates an order row beneath the ticker row. HOWEVER, I often want to create GTC orders after-hours, either to submit them...

    Charts not loading in TWS

    FWIW mine just popped back to life 5 mins ago. But i've seen this before and expect they'll be wonky rest of the day at least.
