For manual trading I prefer SMA. But it is also related to the system.
As to EAs so MA crossing (or EMA crossing) EAs are good to have some profit. But those kind EAs are not as "set-and-forget" ones: it is necessary to check the settings, optimize the settings regularly, check market condition and so on.

For example, you know good setting for IBFX for some EMA crossing EA you are using. And if I use Alpari broker so I will have to optimize your settings with Alpari to get my settings. And performance of those kind of EAs are depending on market condition as well.

Basicly there are two groups of traders: 'Ichimoku indicator' traders and 'MA indicators' traders. They are in competition between each other. So, the performance of MA (or EMA) crossing systems are similar with Ichimoku systems and that is why those groups of traders will always be in competition discussing what is the best or better to use.

MA (or EMA) crossing EAs are not "set-and-forget" EAs concerning the settings and everything and it is too many exercises for me as I always do not have any time at all so I am looking for something more simple: just to attach to the chart and forget for 1 week for example.
EMA crossing EAs or systems are not so simple to trade as people are thinking about.
