I was wondering if anybody has created a data connection provider for NT
What i want to do, is to inject real time synthetic data (data that i have calculated outside NT,
as a result of different processes) back into NT, like a normal instrument.
Preferably in parallel with my existing IQfeed connection.
Is that possible ?
Anybody done any research on this ?
Can you help answer these questions from other members on NexusFi?
You can do this using the External connector, but it won't allow another regular data feed.
If you want a custom data feed to run in parallel with a regular one an option would be create a fake IB connector for example, instead of using the external connector. As the IB API is well documented I assume it won't be too painful to create a service/daemon which will reply to NT requests in a coherent format.
Are you sure this is still possible with NT8? For some reason I had it in my mind they removed that, I thought I saw a post about it maybe a year ago or so.
If NT is running with 2 data feed connections, what decides when I open a chart with an instrument (which is supposed to be a stream of synthetic data i will calculate myself), on what connection the data will be requested ?
1. My plan is to have my broker connection
2. My IQ feed connection for my normal data feed
3. and to have a second data feed connection to my own server (that will clone one of the supported formats)
I create an instrument for my synthetic data, and then NT should request that live data from point 3.
all other things should keep working.
I didn't tested it but in theory:
- you create a synthetic instrument only mapped to your fake data server, let's say using IB API, and not mapped to IQFeed
- you then connect to your broker 1st, then IQFeed, then your fake IB server
- as your custom instrument won't be known by 1. and 2. NT should receive data for this symbol from 3.
I had created the instrument like you mentioned...
I have been looking at the connections...
I found 3 that have a configurable ip address....
The IB is the only running in 64 bit
But i read NT 8 has them all in 64 bit...
My plan is to install NT8 tomorrow
And try to build a small prototype using opensource FIX protocol
I only need history..... So,logon, heartbeat, history, logof...
