Get_Symbology from ISIN to RIC with currency
Royal Dutch Shell has a dual listing with the same ISIN on both LSE (GBX) and on AEX Amsterdam (EUR). The ISIN is the same but the currency is different. When carelessly converting symbology with this information for timeseries/portfolio value calculation can be very dangerous.
As shown below doing a lookup from ISIN to RIC with symbology can get the wrong currency listing. As I have lots of information from third parties from which I don't get a RIC. I am looking for a way to translate an ISIN and an ISOCURRENCY into the right RIC. This issue does not only occur at RDSa but also at many ETFS that are listed with the same ISIN on many different exchanges. How can I best tackle this?
get_symbology( symbol = ["GB00B03MLX29"]
, from_symbol_type = ["ISIN"]
, to_symbol_type = ["RIC"]
)
[[1]]
RIC
GB00B03MLX29 RDSa.AS
As shown below the transformation in the other direction goes ok.
get_symbology( symbol = ["RDSa.AS"]
, from_symbol_type = ["RIC"]
, to_symbol_type = ["ISIN"]
)
[[1]]
ISIN
RDSa.AS GB00B03MLX29
get_symbology( symbol = ["RDSa.L"]
, from_symbol_type = ["RIC"]
, to_symbol_type = ["ISIN"]
)
[[1]]
ISIN
RDSa.L GB00B03MLX29
Hello @laurens,
Now that I better understand what you are trying to do, identify the RIC for specific currency, how about :
- Get all RICs:
df = ek.get_symbology( symbol = ["GB00B03MLX29"] , from_symbol_type = "ISIN" , to_symbol_type = "RIC" , bestMatch = False) ricList = df['RICs'].tolist()
- Get currency per RIC
ek.get_data(ricList[0],['CURRENCY'])
- Pick the RIC with the appropriate currency from the received
Does this work for your use case?
Hello @laurens,
I think using:
ek.get_symbology( symbol = ["GB00B03MLX29"] , from_symbol_type = "ISIN" , to_symbol_type = "RIC" , bestMatch = True)
Is one way to avoid any difference, per Eikon Data API Reference this parameter will yield only primary RIC, of which there can be only one.
Will this help?
Dear @zoya.farberov,
Thank you very much for your fast response. Much appreciated. I am aware of the BestMatch option. Unfortunately, if I have a list of portfolio stocks with an ISIN and ISOcur. it is not so helpful which stock is considered the primary ric. Calculating the portfolio value is not possible without being able to pinpoint the value of the stock in the correct currency. If I own RDSa stock in GBP currency I believe that I am unable to calculate the correct portfolio value if I have an ISIN and isocur.
