A second thing your Forex trading software should be able to do is to allow you to place what are called "stop loss" orders. These are automated orders whereby your currency will be sold if it falls below a certain value that you have specified. This is important, because it keeps you from "losing your shirt" on a trade that is losing money. By defining your stop loss at specific values, you accomplish two things. First, doing so ensures that you don't have to be there in order to have the stop loss order implemented. You simply place it and it is implemented at the appropriate time, automatically, unless you cancel it. It helps keep you from experiencing additional loss.
The second thing placing a stop loss order does is that it negates any psychological factors that may actually help cause extreme losses. Let's say you're losing on a trade and you've placed a stop loss order so that the currency is sold once it drops to two dollars. By doing this, you prevent yourself from risking further loss by saying, "Well, maybe this currency will gain in value once again, so I'm going to stay in on the trade and see what happens." In effect, you are giving yourself an automatic "out" and taking yourself out of the process once that loss has occurred.
Remember that even the best Forex trading software can't do everything. Forex trading software is meant to be a tool to help streamline the Forex trading process for you so that it is automated to some extent. However, you still must have a good solid working knowledge of the Forex system and how it works in order to be able to use your Forex trading software effectively.
