I pull TR.TotalReturn 4w forward return numbers from the API but they are all in local/native currency. How would I convert this number to a USD number. For example when using the RICCode SBKJ.J, the 4w forward return From 2019-07-26 To 2019-08-23 is -6.6597, I've looked on Bloomberg and the equivalent in USD is -12.6257. How do I produce this number in Eikon Refinitiv, I've tried using USD closing price (TR.PriceClose) and ZAR closing prices on 2019-08-23 and 2019-07-26 but cannot produce the resulting number in USD
