Try to optimize the periods of EMAs.

Besides as we know any EAs based on MA or EMA crossing can not be stable with profit with the same settings. It means that you will need to change the settings to new settings every half a year, or every month - depends on timeframe you are using. But it is optional. I mean the following: it is very difficult for find good settings for EMA crossing EA to be the same one for 2 years for example. ! year may be enough. But it depends on timeframe also.
