In order to judge the performance of any forex software, you need to spend time with it. You should get the demo version of that software and should spend at least 15 days on that demo. Within this period of time you will be able to know all the good and bad things about the software. You do not need to worry about losing anything within this period of time as you will be using the software for free and will not be trading with the real currency. You will be using the virtual currency.
During this demo period, you should compare it with the other top forex software programs. You will have to see whether it trades profitably regularly or not. You will also have to look out for the drawbacks in the software. You should also work on the hidden and the advanced features of the software. Once you have used the demo version, you will be able to conclude the following things.
The performance of the software when short term strategy is used: This is the first thing that you will conclude. If the software gives solid performance in the short term strategy and delivers profits, then it has passed your first test.
The performance of forex software in the long term strategy: The second test that your forex software needs to pass is its performance during the long term strategy. If the software has given you profitable trades during the short term strategy as well as long term strategy, then you can call it reliable forex software. It has also passed the second test in that case.
The final test that your forex software needs to pass is safety test. The limits should be kept secret by the forex software. That means the software should be safe.
If it is not keeping the limits secret, then you will be giving a chance to the shady brokers to take advantage of that and hence reducing your chance of making profitable trades. If it has passed this test as well, then you can buy the full version of that forex software without any worries.
