Currently, trading uses the value in target currency (e.g. USD for pair EUR_USD) to make trades. It would be more natural to define the number of units in the source currency (e.g. EUR) when trading from EUR. This is also more natural in working with Oanda, since the units are requested in the source currency anyway.
[ ] Use source currency for definition of amount in Interpreter if source currency is EUR
[ ] If source currency is other than EUR, convert to EUR to determine amount.
