Only one symbol is available for each currency pair, for ex. EUR.USD is available but not USD.EUR. Available currency pairs can be found on the Product Listings page of our website, clicking on IDEAL PRO.
You can use the action Buy or Sell to decide which currency you want to go long (i.e. buy) or short (sell). The action is always referred to the first currency of the pair.
Order quantity is by default in terms of units of the first currency of the pair.
However, TWS allows to input order quantity in terms of the second currency of the pair.
