Brendan is correct about the UNSET_DOUBLE or Double.MAX_VALUE the various languages use to indicate "undefined value". The same is true for integer fields where the Integer.MAX_VALUE (2^31)-1 =

I'm afraid unless someone here is feeling generous you are going to have to 1) get the price feeds, 2) do the maths according to your own flavouring and 3) make it robust to all the errors, data

That value (1.797...e+308) is the maximum value a double can hold. IB uses that to indicate the value is unset. In the C++ API code, they have an UNSET_DOUBLE constant that you can compare against,

Hi all - new to this forum, hoping to learn a lot here! Wondering if anyone has been able to use the excel API to pull in Beta to the S&P500 for a particular stock that is in your portfolio? I am

When I execute an order I get the?commissionReport.But I cannot read the?commissionReport.realizedPNL such like?1.7976931348623157e+308. When I create a new position,

Richard already pointed the relevant time-in-force options out and you can learn more about GTC orders in Good-Til-Canceled (GTC) Orders ( https://www.interactivebrokers.com/en/index.php?f=588 ).

You can’t specify a date with ‘Good Till Cancel’. It just means that the order will remain valid until either it is filled or it is cancelled (for example via CancelOrder): so it will persist

Hi All, I was going through TWS API order structure. I found that we have GTC orders in which we can specify date and time to cancel the order. Why we have seperate field called autoCancelDate? Isn't

Jürgen, First let me apologize, somehow I must have missed your original response with questions, thanks again for taking the time to respond. I am glad you were able to replicate the issue so that

I had a couple minutes and a paper account with no positions and was able to replicate the TWS behavior you report: * A (paper) account has no positions (other than cash) * The portfolio/account

I ran two and more clients connected to the same IB Gateway 981.3o in paper and real accounts and received no error conditions. Everything worked fine, as expected, and just like always, and I cannot

ibgateway is 981 and only the 2nd connected client has 10197...it happens consistently based on previous discussion about 10197 IB definitely changed rules...

Hello Jurgen, Wow thank you for the through explanatio, I super appreciate it! Also I am eager to try to come up with something using your solution;? the IBApi.Order object

Which PNL feed are you trying to subscribe to, Marc? * IBApi::EClient::reqPnLSingle ( https://interactivebrokers.github.io/tws-api/classIBApi_1_1EClient.html#a9ba0dc47f80ff9e836a235a0dea791b3 ) *

Glad this helped. And I learned a few new VIX tidbits, too. Jürgen

Does this happen all the time? Which IB Gateway version are you running, and will both clients get the error? We sometimes (but rarely) see "Code: 10197" errors during the nightly IBKR maintenance

Are you referring to the Global Configuration -> Presets -> ... settings in TWS, Adam? Those only impact orders you manually place from within TWS and they are missing from IB Gateway since it does

Wonderful! Thank you so much. This was exactly what I was looking for.

IBKR has some material online about VIX trading. Among them is this CBOE document from 2010 ( https://www.interactivebrokers.com/webinars/Trading_VIX_Futures_Options.pdf ). On page 17 they describe

Thanks Jürgen. I wasn’t aware of observable data objects, so that is a great tip. Yes, using Python. Sent: Friday, 15 July 2022 1:02 PM To: [email protected] Subject: Re: [TWS API]
