How can I get price history for all dats in a range

I have a REST request that uses the price history Extraction request template to return historical price for an asset/ric.

However, it only returns the price for the last date in the range.


This is despite the template setting a start and end date of the range.

Also - I have set the following template fields:


"QueryStartDate": "2015-12-01T00:00:00.000Z",
"QueryEndDate": "2018-12-03T00:00:00.000Z",
"AdjustedPrices": false,
"LastEntityOnly": false,
"ReportDateRangeType": "Range"


How can I get all prices for the date range specified?

P.S. I have also tried 'DaysAgo' = 30 with "ReportDateRangeType": "Delta" - this does exactly the same thing.

I need data for multiple years.

Thanks

Kashif.

This was a Python code issue, solved outside of the community forum. Thanks to Gareth.

Hi @kashif.sherwany,

Could you share your entire request message? I am able to retrieve data for the specific range using your provided condition. Below is my request.

{

    "ContentFieldNames": [
      "RIC",
      "Trade Date",
      "Official Close Price",
      "High Price",
      "Low Price",
      "Open Price",
      "Universal Close Price",
      "Exchange Code",
      "Currency Code"          
    ],
    "IdentifierList": {
      "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",  
      "InstrumentIdentifiers": [
          { "Identifier": "IBM.N", "IdentifierType": "Ric" }
      ]
    },
    "Condition": {
      "QueryStartDate": "2015-12-01T00:00:00.000Z",
        "QueryEndDate": "2018-12-03T00:00:00.000Z",

Hi @kashif.sherwany,

            "IdentifierType": "Ric",

The code is in python and I am using requests library - like this:


requests.post(url, json=json_object, headers=headers, proxies=self.proxy)

where the json_object is the template I pasted above, and the header just has my token info etc..


could this be a permissions issue?

Hi Kashif,

I have modified an example request for Price History in Python and sent via email. Please let us know if the example On Demand Price History (Range) works for you.

Based on an extraction Notes file I think it unlikely to be a permission issue.

Best regards,

Gareth
