In line with industry standard Refinitiv does not adjust stock price history for cash dividends in most markets. You can use get_timeseries method with fields 'OPEN','HIGH','LOW','CLOSE':

ek.get_timeseries(['TRI.N'],['OPEN','HIGH','LOW','CLOSE'])

Or you can use get_data method with fields 'TR.PriceOpen', 'TR.PriceHigh', 'TR.PriceLow', 'TR.PriceClose', e.g.

ek.get_data('TRI.N',
            ['TR.PriceClose.date','TR.PriceOpen','TR.PriceHigh',
             'TR.PriceLow','TR.PriceClose'],
            {'SDate':'-1M','EDate':'0D'})

For more details see the documentation for Eikon Data APIs. In particular I suggest you check out this tutorial, that talks at length about metadata discovery (finding field names and parameters) for use with Eikon Data APIs.

@Alex, What are the Eikon fields for Open, HIGH, LOW, CLOSE for daily OHLC?

Can you send a link to an python example which pulls this data from EIKON API?

I noticed on the links you sent that your adjusted prices do not contain cash dividends, is that still the case?
