No matter how you choose to trade, manually or automated, a winning strategy is vital. Trading without a clear set-up will lead sooner or later, but most of the times sooner, to financial losses. Even if your preference is to execute your trades based on expert advisers, you still have to use a strategy and be aware of the parameters that rule behind these automated applications. There are other options, of course, like buying a trading system and use it blindly, but is an opportunity I dont consider reasonable for the simple motive, that finally this choice will cost you much more than you are willing to pay and for sure your benefices will convert into losses.
