defining FIDs in websocket API for streaming prices
I use the Python example : market_price_edpgw_authentication
I can run the example but I want to optimize the solution. There is no need to get in the initialization all the available FIDs. I only want to see with the initialization 10-15 FIDs and only want to receive updates for these FIDS. How do I define the FIDS in the request . In the demo video "view" was used but that isn't supported in the Python example.
Hello @wim.ooms
You can add 'View' in the request to specify your preference fields. The example below show how to request BID(FID 22) and ASK(FID 25) field below:
mp_req_json = {
'ID': 2,
'Key': {
'Name': ric_name,
'Service': service
},
'View': [
22,
25
]
}
The example output:
SENT:
{
"ID":2,
"Key":{
"Name":"JPY=",
"Service":"ELEKTRON_DD"
},
"View":[
22,
25
]
}
RECEIVED:
[
{
"Fields":{
"ASK":106.86,
"BID":106.83
},
"ID":2,
"Key":{
"Name":"JPY=",
"Service":"ELEKTRON_DD"
},
"PermData":"AwEBUmw=",
"Qos":{
"Rate":"JitConflated",
"Timeliness":"Realtime"
},
"SeqNumber":9406,
"State":{
"Data":"Ok",
"Stream":"Open",
"Text":"*All is well"
},
"Type":"Refresh"
}
]
You can find view Python example in market_price_batch_view.py shipped with WebSocket API Sample Applications
