TWS API | Options market data request issue.
|
Hello!? I'm trying?to request option chain and subscribe market data, to get prices for options on a given STK contract.
I do client().reqMarketDataType(DELAYED);
client().reqContractDetails(requestId, stkOptionContract); at this moment I have a number of Put\Call contracts,? then I try? client().reqMktData(nextReqId(), optionContract, "", false, false, null); for each option contract.?
Aaand after that I keep getting this message?| 10197 | No market data during competing live session, In very rare cases I could get data, but mostly errors and nothing (like 95% of requests failed). I don't have any other device with TWS, or accounts. Only one I?logged in from this computer. I'm using a paper account for development, and I don't have any subscriptions to IB, could that be a problem?
Still STK market data arrives as it should for any number of requests.?
Thanks!
