When testing a currency exchange system, back testing is exceedingly important, however it is not the definitive test for any forex robot. While a backtest shows how the EA would have performed had it been running during the past, the data historic is not absolutely accurate. Similarly, the past performance doesn’t guarantee future results, so only a system that’s running live can be confirmed, and even then its future is not clear. What does that suggest for traders like you and me? It means that choosing a foreign exchange robot isn’t that straightforward and you have to take care. For instance, there’s a new expert advisor Forex Cash Rocket, and it also show back-testing results. As said before, that doesn’t suggest this system will be rewarding. The only way to make a decision is by monitoring its live performance.
