Running out of resources for measure

[PBI-BOLA]

Hi I have a DAX measure which works fine in a visualshowing the position of a single month but I get a message saying my visual has run out of resources when adding multiple months to the visual. Is this the most efficient formula below and are there ways I can make this same calculation less resource intensive?

Essentially I am converting a measure to a single currency. I have split the measure into multiple sections as there are multiple currencies. The exchange rate is calculated by taking the average from the present month (max month in filters). 
It's divided by 1000 at the end as numbers are to be represented in 1000s

up to line 55 I am converting to the currency of the exchange rate table

56-66 converts the result to USD

67-74 adds data that already exists in USD

Thanks! Had to make a minor change as a filter was missing in ConvertedToUSD, it's working in the service now.
