EA-Wizard: how modify Indicator?

[David Ben Svaiter]

Hi,

I'm starting studing EA and after create a Moving Average EA I'm really lost how to modify the MA lines to start new signals or change lines properties (like color, width and so forth).

Or, in other words: how can I change the code created to allow me make changes without impact the "default" MetaTrader-5 source libraries?

Thank you!
