I am using this API code for HistoricalChain Search but unable to get the Source/Exchange code. What is the reason? Product is Tick History
https://selectapi.datascope.refinitiv.com/RestApi/v1/Search/HistoricalChainResolution
{
"Request": {
"ChainRics": [
"0#.KQ150"
],
"Range": {
"Start": "2023-01-31T00:00:00.000Z",
"End": "2023-01-31T23:59:59.000Z"
}
}
}
Output:
