Dynamic Exchange Rate architecture and DAX calculation in Power BI

I want to get my amount to change as per currency code selected dynamically.

 

In my FactSales table I have currency and Amount. If user want to see that amount in any currency he select the currency from slicer and my excahnge rate will apply to that amount.

 

I tried below DAX to get dynamic Exchange Rate but no luck:

 

 

ExchangeRate = CALCULATE(MIN(ExchangeRate[ExcahngeRate]), FILTER(ExchangeRate, AND(AND(AND(MIN(FactSales[TransDate])>=MIN(ExchangeRate[ValidFrom]), MIN(FactSales[TransDate])<=IF(ISBLANK(MIN(ExchangeRate[ValidTo])), DATEVALUE("01-01-2070"), MIN(ExchangeRate[ValidTo]))), MIN(ExchangeRate[FromCurrencyCode]) = MIN(FactSales[CurrencyCode])), MIN(ExchangeRate[ToCurrencyCode]) = FIRSTNONBLANK(ExchangeRate[ToCurrencyCode],1))))

 

ExchangeRate = CALCULATE(MIN(ExchangeRate[ExcahngeRate]), FILTER(ExchangeRate, AND(AND(AND(MIN(FactSales[TransDate])>=MIN(ExchangeRate[ValidFrom]), MIN(FactSales[TransDate])<=IF(ISBLANK(MIN(ExchangeRate[ValidTo])), DATEVALUE("01-01-2070"), MIN(ExchangeRate[ValidTo]))), MIN(ExchangeRate[FromCurrencyCode]) = MIN(FactSales[CurrencyCode])), MIN(ExchangeRate[ToCurrencyCode]) = FIRSTNONBLANK(ExchangeRate[ToCurrencyCode],1))))

If we have Exchange rate on daily basis then we can go for below solution:

If we have Exchange Rate as date range then use dynamic DAX:

ExchangeRate = 
IF(ISBLANK
	(
		CALCULATE(MIN(ExchangeRate[ExcahngeRate]), 
		FILTER(FILTER(ExchangeRate, AND(AND(ExchangeRate[FromCurrencyCode] = MIN(FactSales[TransactionCurrencyCode]), ExchangeRate[ToCurrencyCode] = FIRSTNONBLANK(ExchangeRate[ToCurrencyCode],1))
		, MIN(FactSales[TransDate])<=IF(ISBLANK(ExchangeRate[ValidTo].[Date]), DATEVALUE("2070-01-01"), ExchangeRate[ValidTo]))), MIN(FactSales[TransDate])>= ExchangeRate[ValidFrom]))
	)
	, 1
	, CALCULATE(MIN(ExchangeRate[ExcahngeRate]), 
		FILTER(FILTER(ExchangeRate, AND(AND(ExchangeRate[FromCurrencyCode] = MIN(FactSales[TransactionCurrencyCode])
		, ExchangeRate[ToCurrencyCode] = FIRSTNONBLANK(ExchangeRate[ToCurrencyCode],1))
		, MIN(FactSales[TransDate])<=IF(ISBLANK(ExchangeRate[ValidTo].[Date]), DATEVALUE("2070-01-01"), ExchangeRate[ValidTo])))
		, MIN(FactSales[TransDate])>= ExchangeRate[ValidFrom]))
)
