On the page with the list of tick types ( https://interactivebrokers.github.io/tws-api/tick_types.html ), I see "Auction Price" which is the "The price at which the auction would occur if no new

I am using C++. The last arg, the TagValue list exist too, as I can see it in the C# doc https://interactivebrokers.github.io/tws-api/historical_bars.html but I never filled it with anything.? Seems

Which TWS API version are you looking at, Shaun? I just checked 10.19 "stable" and 10.20 "latest" and the reqHistoricalData request signature contains the boolean keepUpToDate and the chartOptions

If you read the man page for fork carefully you'll see it says... *The child process and the parent process run in separate memory spaces.* And, Jürgen kindly pointed out that the API *works well

I am working in C#. I don't know if this feature works the sake in other languages or not. I want to make a Historical Data Request with Keep Up to Date set to true. However, the signature for

You can use a class for each process: And in main: Que'ing in and out of a class/process makes it easy to add more processes when you need more expediant data processing. You can push a fairly large

Multi-processing works well with tws-api. I use ques to pass information between processes, which I found more ideal that shared variables and locks.

Thank you, Jürgen! In python most TWS API example show how to create new thread and run TWS API reader in there. As far as I know in Python threads cannot run in parallel due to GIL (general

What is it that you are trying to achieve? Why is the "standard" way of using TWS API insufficient? TWS API runs a reader thread that receives all communication data packets from TWS/IBGW, decodes

As a C++ user what do I need to do to clear this issue?

I would like to let you know the latest Beta version I just tried today seems to fix the issue : version 10.21.0w. They added a tick box in the API settings (at the very bottom) to ? Send Forex

Good point about the restart. I got the automated notifications working again, but I had to delete the app and reinstall without restoring the previous activation to make it work.

I frankly understand your frustration. However, lots of pain can be taken off the process. Most recent TWS include a "restart" in the menu, which makes it unnecessary to enter your pin on the IB app

hymagik is correct about the somewhat messy C++ Decimal support and the fact that IBKR has selected a decimal size of 8 bytes (64 bits). To be more precise, IBKR decimal uses a "MathContext with a

There are really no settings you can change. You would have to use a TWS API Version of at least "163" for any of the fractional size rules to work. rossh_yh mentioned that "163" is available in TWS
