Costs of conversion of non-dollar forex account

[dobrek]

Hello,

I am new to Forex, so please don't execute me if the following

question is naive.

Losses or profits in pips are converted into dollars according to

certain formulas. If my account is not in dollars, but, say, in euros

or Swiss francs, these dollars are converted to euros or Swiss

francs. Is there something like a spread in this conversion from

dollars to the account currency? I.e. is it a disadvantage to have a

forex trading account in a currency other than US dollar (all other

things being equal)?
