What are the important apps that I can download for trading?
After you choose the Broker that you are going to trade through - you just use the trade terminal that your Broker supports. Like MetaTrader 4 or 5 - they have got everything you need to start. And later on - you might want to add some custom expert advisers, that could be programmed yourself or downloaded from Internet.
