Get exchange rate on a specific date from GoogleFinance

Question

I\'m having trouble stopping the googlefinance function on a specific date to use \"that\" specific exchange rate to convert currency from GBP to EUR.

Here is my formula

Answer 1

Here's my version of this formula.

Where B3 should be valid date.

=index(GOOGLEFINANCE("CURRENCY:USDCNY", "price", B3), 2, 2)

PS. I'm not sure why, but when I specify the 15-Dec-2018 the formula shows me an error. All other dates are work correct.
