Simple answer is yes. One of my EAs applies its buying and selling strategies to every currency pair in my watch list from the one instance. In coding terms, you need to start referring to specific currency pairs and not just the one in the current window. So, in MT4 for example, instead of using 'Ask' you would you use 'MarketInfo(...the currency pair...,MODE_ASK)' where you fill in the correct currency pair or symbol. HTH Alex
