Thank you very much, Richard, Franco, and Hartmut. Richard, you are right, "the program just runs requests that are hard-coded into it: no GUI, no command line." I am trying to use MFC Dialog-based

Hi I am trying get my code to match the spread valuation in TWS L Mar20 '24 / Sep17 '25 Calendar ICEEU Here is my attempt: ( ( ( LH24[bid_price] - LU25[ask_price] ) - fill_execution_price ) /

I think the answer to your question is that the program just runs requests that are hard-coded into it: no GUI, no command line. So you should be able to modify it to request market data for YM. I

You can request for a stream quotes of the futures symbol for Dow 30 index just by coding it using this as a guide:

Why don’t you start slow? Try to grasp how to interact with cpp or python code compiling it from the terminal or an IDE.

Perhaps you are looking for a working console to enter api-commands? That's wired, because you end up with a cryptic code. Are you are looking for a terminal-console to enter high-level code (java,

Thank you for your response. Then where should I enter a request for a stream quotes of YM (the futures symbol for Dow 30 index)? Do I have to run the program with a parameter (a futures contract

I can't agree with this.? Callbacks aren't simpler, they are just older.? Having to write a special class just to make an API call is really weird.? It introduces all sorts of weird issues about

I would prefer to separate thread-safety and concurrency properties?of ApiController. Adding Futures doesn't solve thread-safety and rises an entry bar. Once ApiController is thread-safe, methods

If you are going to make the IB API thread-safe, you should do it with Futures.? There are probably plenty of non thread-safe things in the ApiController and the library.? The biggest headache for

Yes, that’s a fork of TWS API, so you have to request a contributor license.

Interesting, Artyom. We did something similar a few years back and use our AprControllerEx ever since. Was just trying to check out the repository but get 404 errors with and without being logged

FWIW, I think IBK did about the best that could be done by putting out there a minimal library capable of demo executions, yet is amenable to taking in different architectural directions via layering

Hi Good progress was made to make com.ib.controller.ApiController thread-safe. Besides thread-safety, this branch contains re-implementation of error propagation approach. Lets discuss

Nick, in the context of Java, I think my usage of 'atomic' was correct. See the following:

Ibapi code can be run from terminal. You don’t need a GUI.

Thanks.

Yeah, (out) is a good idea.

[resent due to formatting issues] . No disagreement here. It is just that m_reqId++ is not one step but (at least) four: load, copy, increment, and store. In Java possibly unboxing, boxing, and
