At the moment get_timeseries method can only provide adjusted price history. This is a known issue that's been reported previously on this forum
https://community.developers.refinitiv.com/questions/17906/corporate-action-unadjusted-prices.html
What you retrieved is the adjusted prices, however it looks like you may have a different definition from the market convention of what you consider adjusted prices. Most market data vendors including exchanges and aggregators such as Thomson Reuters automatically adjust stocks' prices histories for capital changes. However the practice of what to consider a capital change event requiring stock price adjustment differs by market. E.g. in Brazil the market practice is to adjust stocks' prices histories for dividends whereas in the US the practice is to exclude dividends from capital changes requiring adjustment of a stock price history. I'm not a market specialist, but by the looks of it Norwegian stocks are not adjusted for dividends. You can check the price history for Marine Harvest on Oslo Bors' Web site and see that the closing price for 01-Nov-17 is 159.9.
https://www.oslobors.no/ob_eng/markedsaktivitet/#/details/MHG.OSE/overview
The last capital change adjustment for this stock was on 20-Jan-14 when there was a 10:1 consolidation for this stock. The unadjusted and adjusted close prices for this stock on 20-Jan-14 were 7.695 and 76.95.

Thanks for your answer. Stock prices need to be adjusted for dividends/splits to be able to use them to accurately calculate returns or compare time series.

On this page you can see adjusted/unadjusted prices for Marine Harvest

https://investor.dn.no/#!/Aksje/S137/MHG/MarineHarvest

(Under graph -> Kursjustering)

Do you know if this is something that will become available in the near future?

Adjusting for splits and dividend is absolute necessary if you want to use the prices for quantitative analysis. Yahoo finance had option to do this, so I think this is quite basic feature.

I'm not aware of any plans to introduce any types of stock price history adjustment in addition to already available adjustment that follows standard market data practice. If for your analysis you need to adjust Norwegian stocks prices histories for dividends following the methodology of your choosing, you can do it yourself: retrieve the price history, the dividend history and do the adjustment. The site you referenced appears to simply subtract dividend amounts from stock prices, though I might be wrong about that.
