Well, somewhere in your program an API request is made with a duplicate requestId or tickerId. The error callback should give you the exact id at fault.

"reqId + counter" is a bad idea. You should have a function, such as nextRequestId(), that provides a new and unique Id every time the function is called. It is sufficient that the function simply returns the value of an incremented variable such as (pseudo language):
private integer _nextRestId = 10000000;
funtion integer nextRequestId()
{
??? return _nextRequestId++;
}
We found it helpful to start request Ids at a high number so that they cannot be confused with orderIds.? But "_nextRestId? = 1" will work just fine.

Now, every API request (not just reqMktData) gets a unique Id by a call to nextRequestId().

How to close very OTM Long options after disassembling one Iron Condor

#50670

Hi there!

I wonder if any of you have solved this problem or has any clues to try to solve it altogether:

I need to close two Long OTM options positions (which worked as a cover of an Iron Condor) after the SHORT legs combo is executed. as the Long legs are very OTM they usually?have no bid price (so you can not always sell them inside a 4 leg combo).

Example?

1) IC bought:

1? SPX? 4100C

-1 SPX? 4050C

-1 SPX? 4005P

1? SPX? 3955P

2) After I got into the position I place the exit disassembled combo order (just two legs) with SL price to exit the position:

-1 SPX? 4050C

-1 SPX? 4005P

3) after?position 2) the exit combo is executed/closed

This is what I can not solve:

I want to close/sell each of the long legs remaining: 4100C and 3955P (without having to monitor it) By attaching an order or creating a conditional order or any other way to close the position without having a program/algorithm to check this.

I've tried to add child orders of each of the legs, but needs to be the same type (combo) I tried Hedge legs but just get one closed and the other one cancelled

Have any of you have successfully?done this? Any workarounds, please?

Thank you

The time format you use for lastTradeDateOrContractMonth is incorrect. Check the in the for the correct use.

You can also make your life easier by simply using localSymbol, such as LEH3 for the current front month, along with secType FUT and Exchange CME.

TWS API 10.20 c++ windows

#50660

Hello,

i have a basic question and i am sure this is boring for the most of you but I NEED YOUR HELP.

I am using the API since years but til now i have used an old on.
The old API software i have c# and coliped it with nmake. No problem on this.

NOW, i have to switch to API 10.20.
And i have problem to compile the c++ code on windows.

Did anyone of you have a good dicription that a normal people like me ould understand an can compile the 10.20 API c++ on windows.

I would be very thankful if anyone of you could send me some information.

Sorry again for this basic question.

Best regards

Re: historical futures quotes for expired contracts

#50659

Although you don't mention which error message(s) you are getting, last time I checked you needed to set the end date/time parameter in the historical data request call to a date/time within the life of the expired futures contract (preferably near, or at, the expiration date of the contract). Hope this helps.

Re: historical futures quotes for expired contracts

#50658

While it worked overall--obtaining quotes for expired futures contracts---, your suggestion of combining (local?)symbol and exchange hasn't worked for me specifically because I did some custom modification to the 2019 version api which requires going under the hood. but not urgent at present.? For longest my practice has been locking it down with conId. But since I have the data I need, for now I am good.? Additionally, sometime last year, there was a huge IB move of futures contracts between exchanges-- from GLOBEX to CME which factored in my query.? Thank you kindly for your help and flexible thinking!

reqMktData returning wrong tickPrice for Index

#50657

Hi,
I am from India and trading on Indian Exchange (NSE) leveraging TWS API. Today, I have received a wrong NSE Banknifty index tick data at 2023-01-30 15:10:01,031. Please refer the log below
2023-01-30 15:10:01,031 ibapi.wrapper - INFO - ANSWER tickPrice {'reqId': 9, 'tickType': 4, 'price': 40103.0, 'attrib': 140654527663168: CanAutoExecute: 0, PastLimit: 0, PreOpen: 0}
The price report was 40103.0 which is completely wrong. Infact, it was trading around 40327

I have used reqMktData as below -

self.ibkr_app.reqMktData(reqId=evt_id,

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? contract=self._getUnderlyingContract(instr),

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? genericTickList="",

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? snapshot=False,

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? regulatorySnapshot=False,

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? mktDataOptions=[])

Within one milisecond, I received the right price though, i.e. 40327 -
2023-01-30 15:10:01,032 ibapi.wrapper - INFO - ANSWER tickPrice {'reqId': 9, 'tickType': 4, 'price': 40327.0, 'attrib': 140654527663168: CanAutoExecute: 0, PastLimit: 0, PreOpen: 0}

1. May I know if this is normal to receive such wrong data intermittently ? And how should it be handled in the program ?
2. What is the best practice to receive market data repeatedly ?

Thanks,
Souvik

Re: historical futures quotes for expired contracts

#50656

What data are you trying to request and what error do you get?

Just tried 1min bars through reqHistoricalData for a few days in February 2022 and promptly got 8,000++ records back.

Making your own Contract objects is often hit or miss since you never know exactly which Contract object fields IBKR expects for the various requests. And there are differences between historical data, tick by tick data, and order placement.

A best practice is that you call (as described in ) and use the contract object they return for your requests. You can, for example, request the contract by symbol and exchange (such as 6MH2 and CME) or just the conId (as I did since you had provided it)

Re: I am trying to setup IBAPI for interactive brokers using python 3 and pycharm

#50654

I realize this is an old thread, but I'm responding anyway, as it may help someone who runs into this in the future.

I was running fine until I decided to upgrade from python 3.10 to 3.11. I reinstalled the TWS API, but it continue to complain that IBAPI is not installed. The problem in my case was the multiple python versions. I set the path to default to python 3.11. Checked to make sure that it was defaulting to 3.11 by checking the version when I run python from the command-line. Then I ran C:\TWS API\source\pythonclient\setup.py again. Restarted VS Code and it works fine now.

Re: eroor 322 errorMsg "Error processing request.-'bW' : cause - Duplicate ticker id"

#50653
Edited

I don't understand your comment, Dmitry, why centralizing the ID generation still can get duplicate IDs.

I presented a pseudo language example but every language has concepts that make nextRequestId() a strictly monotonically increasing function. In other words, each call returns a number this is higher than all other numbers returned before and no number will ever be returned again. And that is guaranteed regardless of how many threads and loops execute in parallel.

In Java, for example, you can simply declare the function as public synchronized or use an AtomicInteger instead of simply int. For many years we run applications with many parallel threads on systems with several processors and have never seen error 322.

Now, the real solution here is an application architecture that completely removes request Ids (and other API details) from the business logic. Such as wrapping a thin controller layer around TWS API calls so that these implementation details are completely hidden from client code. A good example is the ApiController class that is part of the TWS API Java version. So, instead of calling the TWS API method

reqMktData( int tickerId, Contract contract, String genericTickList, boolean snapshot, boolean regulatorySnapshot, List<TagValue> mktDataOptions )

and having to manage request ids and having to implement routing code for returned data by requestId to your appropriate logic you simply call

reqTopMktData( Contract contract, String genericTickList, boolean snapshot, boolean regulatorySnapshot, ITopMktDataHandler handler )

and the controller automatically routes the data stream directly to your handler function.

Or look at Ewald de Wit's very well architected ib_insync Python library, and you receive the subscribed data streams via asynchronous events whenever they arrive.
