As it turns out, my program did not stop reading the messages, it just didn't read them fast enough. After a period of time, the EBuffer in the TWS Gateway hit ~ 5Mb, then disconnected my client

Rob clearly has data needs that require a dedicated data service provider, which IBKR is not. They are a brokerage. But the IBKR data features are adequate for many (maybe even most) users, especially

I just moved over to IBKR a few months ago, and was thinking I could get the same data I had been getting from Polygon, cut that cost, and just use IBKR, I quickly found out I was wrong. Issues with

Thank you for your kind words, Rob. There are many reasons for abstraction layers (or wrappers, adapters, controllers, design patterns ...) The ability to hide implementations details and facilitate

Thanks for the info. May you please share what headaches you had in using IBKR's data? Just to be curious, as I also need a data source. ________________________________ Sent: Saturday, February 5,

Jürgen, You always have such great responses. If I see you replied to an email to anyone, I always open it. So thank you for all your valuable help. In your reply you discussed abstraction layers. I

The limitation is that interactive brokers is a broker, not a data provider. You can pull data, but it's not worth the headache to me, because everything IBKR does is centered around their core

May I know what restrictions or issues the TWS API has that prevents it from being a data provider? Having a dedicated data source is fine - but adds another dependency for an auto trading system...

Got you, totally agree. In the case of something going wild, I can imagine I'd open up anything available to recue ? ________________________________ Sent: Saturday, February 5, 2022 4:57 AM To:

Thanks again for the detailed info. It seems Java is the way to go ? The other thing matters is how many folks in the community (e.g., this email group) use a language - so I can get some help when

Well that was an easy fix! Thanks!

Do you mean ibapi?

Joan Well, I did find time for this today after all (change of priorities). And I have to say, I was unable to reproduce your issue. I started by amending the demo program I mentioned earlier, to

Hello Folks, I am attempting to install abapi for use with the python TWS-API. Running pip install abapi gives the error message Defaulting to user installation because normal site-packages is not

I agree with this and would add that it will take way more time and effort to implement your system with IB Api than it should. There are numerous gotcha's and general wackiness that you will just

IB says in their TWS API documentation that the intended use of the API is not as a data provider.? That continues to show itself to be true.? I use polygon.io for data and IB for trade executions,

Hard to add much to the answers here but I will agree that seeing my automated trades go through on the GUI is nice.? I trade every market day and will sometimes cancel an order because something

When I said "clients" in my previous posts I was referring to TWS API client applications, not people who hire you. So if, for example. your API client application has placed a few orders but then

Thank you, Nick. Checked the API reference provided by Jurgen, so yes, useful things are hidden. ?? ________________________________ Sent: Saturday, February 5, 2022 3:07 AM To: [email protected]

Thanks for such detailed information, again, Jurgen. I was surprised to learn the conid actually has a look up API - thank you! So based on your info, I will definitely go with IBGW - I don't have
