I can get RIC rename history using HistoricalSearch for a single RIC or ISIN
{ {protocol}}{ {host}}{ {api}}Search/HistoricalSearch
but I want to know a way to send single request for multiple symbols.
Basically, I have 30000 symbols and I want RIC rename history of each of them, what's the best way to go, as using HistoricalSearch route is quite costly.
Hello @ykr1314,
There is also a way to request various change events via TickHistoryTimeAndSales request. Please try this:
{
{protocol}}{
{host}}{
{api}}Extractions/ExtractRaw
{
"ExtractionRequest": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.TickHistoryTimeAndSalesExtractionRequest",
"ContentFieldNames": [
"Symbology Change - Change Type",
"Symbology Change - New Value",
"Symbology Change - Old Value",
"Reference Change - Change Type",
"Reference Change - New Value",
"Reference Change - Old Value"
],
"IdentifierList": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
"InstrumentIdentifiers": [{
"Identifier": "SUNW.O",
"IdentifierType": "Ric"
}],
"ValidationOptions": null,
"UseUserPreferencesForValidationOptions": false
},
"Condition": {
"MessageTimeStampIn": "GmtUtc",
"ApplyCorrectionsAndCancellations": false,
"ReportDateRangeType": "Range",
"QueryStartDate": "1990-09-29T00:00:00.000Z",
"QueryEndDate": "2017-11-28T12:00:00.000Z",
"DisplaySourceRIC": true
}
}
}
The result should contain all the renames
