Historical closing price of stocks using API

Hemant · 2025-04-01T09:56:47+00:00

There was an error rendering this rich post.

I have a dynamic set of stocks (RICs) for which I want to get the closing price data from say last 6 years on daily weekly and monthly level in USD. How Do I do that using LSEG APIs.

Thank you for reaching out to us.

You can use the get_history method in the LSEG Data Library for Python to retrieve historical data.

For example:

df = ld.get_history(
    universe = ["IBM.N","MSFT.O","GOOG.O"],   
    start= "2024-01-01",
    end = "2025-03-01",
    interval="daily")

df

If you don't specify the fields parameter, it will return all available fields. Otherwise, you can specify the required fields in fields parameter, such as TRDPRC_1.

df = ld.get_history(
    universe = ["IBM.N","MSFT.O","GOOG.O"],
    fields = ["TRDPRC_1"],
    start= "2024-01-01",
    end = "2025-03-01",
    interval="daily")

df

You can change the start, end, and interval parameters and use the help command to list all parameters.

help(ld.get_history)

The examples are also available on GitHub.

Thanks for the response @jirapongse. How do I make sure these closing prices are in USD?

I forgot about the currency. In this case, you can use the TR.ClosePrice field.

df = ld.get_history(
    universe = ["IBM.N","MSFT.O","GOOG.O","PTT.BK"],
    fields = ["TR.ClosePrice(Curn=USD)"],
    start= "2024-01-01",
    end = "2025-03-01",
    interval="daily")

df

Thanks again @Jirapongse .

We are not there yet.
The following 2 are the excel formulas that I am using so far and want to now use APIs to get these data points.
———————————-——
1) DSGRID(MASTER_LIST!$A3:$B3000,"1000*X(RI)~U$/MSACWF$(RI)","2022-01-01","","D","CustomHeader=true;CustHeaderDatatypes=RIC;RowHeader=true;ColHeader=true;DispSeriesDescription=false;YearlyTSFormat=false;QuarterlyTSFormat=false;Sym=RIC;MonthlyTSFormat=True","")

2) @DSGRID(MASTER_LIST!$A3:$B3000,"X(RI)~U$","2022-01-01","","D","CustomHeader=true;CustHeaderDatatypes=RIC;RowHeader=true;ColHeader=true;DispSeriesDescription=false;YearlyTSFormat=false;QuarterlyTSFormat=false;Sym=RIC;MonthlyTSFormat=False","")
———————————-——

With respect to the above two
a) 1000*X(RI)~U$/MSACWF$(RI) : Here I believe we are trying to get a relative price of the constituents (in master_list a3-b3000) against an index.

b) X(RI)~U$ : Here the absolute prices for the same instruments.

This is exactly what I am looking for.

My thought was

df = ld.get_history(    universe = ["IBM.N","MSFT.O","GOOG.O","PTT.BK"],    fields = ["TR.ClosePrice(Curn=USD)"],    start= "2024-01-01",    end = "2025-03-01",    interval="daily")df

For example will yield the answer atleast for the point I mentioned above in 2nd, but It wasnt really matching up.

Can we try to convert 1) and 2) i.e. mentioned excel formulas into python code?

DSGRID is a Datastream product. You can use the Datastream Web Service to retrieve data.

The DatastreamPy Python library is available on Pypi.

The code looks like this:

df = ds.get_data(tickers="@GOOGL,U:IBM", 
                 fields = [
                     "1000*X(RI)~U$/MSACWF$(RI)",
                     "X(RI)~U$"],
                 kind=1,
                 freq='D',
                 start="2022-01-01")
df
