[Rami Ramich]

hello,

i tried to get VIX from ibtest - no success.. How to get VIX in realtime?

python ./ibtest.py --data0 VIX-IND-CBOE --timeframe Seconds --port 4001

Isn't that symbol for the continuous display in TWS? If yes, that's an artifact in TWS. You cannot get continuous futures over the API.

[Rami Ramich]

it's index, should be no problem to get it, qtpylib getting it from same 4001 port.
looks like there some issue.

[backtrader]

The symbol may need to be more specific (getting the currency added for example). I don't know the complete specification for that symbol.

[backtrader]

Another possibility is that the symbol was not yet trading real-time ... and the sample will therefore wait until it does to find out how much it can back-fill.

Add --historical

there no trades - it's index.

[backtrader]

Most indices (there may be many I am unaware of) trade (in the sense that they are calculated) between A -> B and don't have real-time ticks between B -> A.

If VIX-IND-CBOE trades 24 hours a day non-stop, the situation may be different.

As stated above, the symbol specification may need extra data.

[Rami Ramich]

this info - from the terminal

similiar to sample with GBP.USD

[Rami Ramich]

@backtrader, here working sample from ezibpy

when i put into ibtest.py VIX-IND - getting following error:

***** STORE NOTIF: <error id=16777216, errorCode=200, errorMsg=No security definition has been found for the request>
***** STORE NOTIF: Ambiguous contract: none/multiple answers received
***** DATA NOTIF: DISCONNECTED

[Rami Ramich]

@backtrader, can you please advice how to handle such index with in backtrader (i think to move into this platform).

[Rami Ramich]

@backtrader as I understand there some difference between handling market data and real-time data (that not traded, like indexes) - I open bug in github - the author closed it. how can this issue be resolved?

[backtrader]

@rami-ramich said in ibtest.py and vix?:

There seems to be misunderstanding from your side, there is no such difference. The only thing that was stated above was about opening and closing times. Even if an index isn't directly traded, it is only active during trading times.

@rami-ramich said in ibtest.py and vix?:

I open bug in github - the author closed it. how can this issue be resolved?

Yes, closed. Opening an issue while discussing here is not very productive.

You are confusing issue with something you are not able to achieve. The ibtest.py is a sample with complex behavior intended to test many different behaviours and situations. It is not a one stop shop: "it is going to do exactly what I had in mind".

@rami-ramich said in ibtest.py and vix?:

when i put into ibtest.py VIX-IND - getting following error:

The Interactive Brokers API doesn't specify how applications gather the needed info for a ticker. If that notation works with some applications, it may not work with backtrader and may not work with many other applications. That notation is not related to how the information is passed to the IB API.

See here for more info, since you are not resampling and the test is probably failing due to it:

• https://community.backtrader.com/topic/124/ib-backfilling-gap/2

  Specify --resample and you will probably get data.

And this which shows how to do it with your own code and not rely on something which is possibly not intended for your use case such as ibtest.py

• https://medium.com/@danjrod/interactive-brokers-in-python-with-backtrader-23dea376b2fc

[Rami Ramich]

@backtrader Thank you for a quick response.
I already tested with --resample option - no index data, when the market was open.
i will try when market will open with this sample from medium.

I very hope i will get this index at real time.

Thank you.

[Rami Ramich]

deleted...

[Rami Ramich]

I played with ibtest.py from sample folder.
historical data it's able to get, but real time - unable...
it's receive index as debug output <tickPrice tickerId=16777217, field=4, price=15.78, canAutoExecute=0>

Could you please point me to any sample that access to any index ticker?

[Rami Ramich]

@backtrader, could you please help me with the issue?

[backtrader]

That only says that if the price is -1.0 the message has to be ignored. That's also for CASH (or CFD) markets (for example: Forex pairs like USD/JPY)

For an IND the subscription is for tickstring messages and not tickprice messages. And for real-time the code is waiting for a tickstring with price information and the message apparently ... doesn't arrive.

[Rami Ramich]

@backtrader thank you for quick answer.
Could you please advice how to fix or workaround it?
I need this IND for the algo.

I coded this - could you please tell if this OK?

@rami-ramich said in ibtest.py and vix?:

Could you please advice how to fix or workaround it?

VIX is not an index which has ever been accessed over here.

and get error... without --resample

@rami-ramich said in ibtest.py and vix?:

I coded this - could you please tell if this OK?

As expressed above. No access to your VIX.

@backtrader my code modification is working, i have access to VIX-IND-CBOE data, but from your point of view modifications are OK? can you merge into main branch?

the crash stack i provided happen inside of backtrader framework.
