I see the same. It looks like you only get VOLUME or BARCOUNT if you ask for TRADES. That doesn’t seem unreasonable to me. Richard

I just ran your sample program again, after hours w/ realtime, data_lines=75, loops=5 and everything worked OK using IBGW 10.30.1s. IDK what to say... I may try it again tomorrow since you indicate

Thank you very much! yes, I can confirm it is there, at least it was all day for me on that very code and right now. (yet it is funky atm, see end of post) can you run it with several loops? It is

I presume you mean the problem <ins>will still exhibit itself</ins>. Can you confirm? Because I just ran your last sample program (w/ inconsequential changes for convenience; see attached) against a

Just run a couple of more tests (using the app I posted, just changed False to True and commented cancel request). Snapshot works 100% reliable as Daniel experiences i.e. snapshot delivers all that is

yes it is the same call I am making, except I am not asking for snapshot (4th argument is False) but whole set of data to be streamed to me self.reqMktData( orderId , contract , "" , False , False ,

Hi AJ, I connect via TWS and my TWS version is 10.30.1s, whereas the version of my CSharpAPI.dll is 10.15.2.0. "I didn't receive all of ["bid", "ask", "last", "volume", "last_timestamp", I think

In the attached zip I have the app. It is now only 250 lines including all the IB connection and argument parsing. The working function are all the same as before ( described earlier) (

Thanks Daniel, Just to be clear the problem is not that I am not receiving the callbacks at all. The problem is that I am receiving not entire set of? the data I expect for some of the contracts

Thanks. I've already tried using US format like SPXW ?241218C05945000 but for some reason it still couldn't find the contract. I just tried again and it seems to work now.

Yes, I mentioned that I can use TradingClass to separate monthly and weekly options. The problem is that it is supposed to be generic method that I could use to form a contract for any security type,

The Contract Inspector shows you the actual local symbol to use. US options and European options have different local symbol formats: you’ve tried to use the European format for a US option.

Hi AJN. First off: note that `Contract.primaryExch` is not the same as `Contract.Exchange`. You might be constructing invalid Contract objects. About reqMktData: just for fun I checked my code and

Pull it out and make it stand alone. Get rid of **ALL SUPERFLUOUS** things like colorization constants... or no one will want to help you.

For SPX OPT you have to set up `Contract.TradingClass` as `SPX` for monthlies and `SPXW` for daily/weekly expiration. Do not define `LocalSymbol`. For naked SPX options, just do `Symbol`,

Create 3 separate orders. TP and SL orders will have property "OrderId" that should be the same as the main order ID. The first two orders will have property "Transmit" set to false, the last one is

Could somebody advise why I'm getting "No security definition" error for a contract with this local symbol : *C SPX 20241218 5945 W* Security: SPX index Strike: 5945 Side: Call Expiration:

Hello, all, I am available for API dev work if anyone needs an extra hand

I created a second version where I removed all code which is not absolutely necessary It is roughly 150 line of code which one easily sees comparing Program.py from samples to *Program_get_bid.py*. As

I have implemented reqContractDetails and start constructing contract using conId I received. so instead of this Like this It made no difference, unfortunately. still not receiving some data
