I wouldn't use Dynamic for that. Do should suffice:

Do[Pause[5]; If[FinancialData["EUR/USD"] > 1.35, sm[FinancialData["EUR/
USD"]]; Abort[]], {i, Infinity}]

so after the first instance of a true test you stop the run (I'm
assuming that is what you want to do?).

...but you need to check that Wolfram update their financial data on
that sort of timescale.
