There is the "Exchange Code List" field in TermAndConditions report which returns a list of exchange code the security is traded on. The list of exchange codes can be found in this table.
Below is the sample of On Demand extraction request.

{
"ExtractionRequest": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.TermsAndConditionsExtractionRequest",
"ContentFieldNames": [
"Exchange Code List"
],
"IdentifierList": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
"InstrumentIdentifiers": [
{
"Identifier": "BH4HKS3",
"IdentifierType": "Sedol"
},
{
"Identifier": "US4592001014",
"IdentifierType": "Isin"
}
],
"ValidationOptions": null,
"UseUserPreferencesForValidationOptions": false
},
"Condition": null
}
}
This method of using TermsAndConditions to return the exchange list returns too many exchanges when requesting with a sedol identifier. (Using the InstrumentSearch the correct number of exchanges are returned, but InstrumentSearch is too slow.) For example sedol 2140863 returns the following list:
ADC,AEX,BAT,BCO,BER,BOS,BTY,CIN,DEA,DEX,IEX,LMA,MEX,MID,NBA,PCQ,PPB,PSE,SES,SIG,TDG,THM,XPH
But the above is the ISIN list, and the sedol list should only have:
ADC,BAT,BOS,BTY,CIN,DEA,DEX,IEX,MID,PCQ,PSE,THM,XPH
How can I use TermsAndConditions to get the correct list based on the sedol identifier?
It seems that the "Exchange Code List" field provides exchange codes for all cross references including extensive instrument identifiers such as Sedol: 5661855, 7681022, 6350776 and B1G7Z62.
Below are the list of symbols in the Cross reference for Sedol: 2140863.
