How does one request multiple contracts together?
{“symbol”: “ABC”}
{“symbol”: “EFG”}
does not seem to work.
Also is there a mapping between contractID and name? (ES == 2345678)
Thanks.

You’d have to send multiple getChart
requests from the Market Data socket you are connected to. One for each contract. Then you’d need to filter the responses, most likely by contractId
, or realtimeId
from the getChart
response.
Yes, there is a mapping between contractId
and name
. You can use /contract/find?name=ABCx1
or /contract/item?id=2345678
based on what information you have. You can use /product/find?name=ABC
to get the product information for a given symbol as well.
The method I’ve described assumes you use the REST API to make those requests, but you could adapt those requests to our websocket protocol quite easily (eg. contract/find\n8\nname=ABCx1
). You can read about the websocket request protocol here.
