I am about to subscribe for a month so I can build some portfolio robots. I have previously done a 15-day trial of Forex Robot Factory and built some EAs, so I am broadly familiar with the process.

Do I need to show all the indicators used by a strategy or portfolio? I can do this relatively easily when using a single-strategy EA, but I imagine that when using portfolio robots, the screen will get crowded with indicators and becomes unmanageable.

Are the EAs capable of working without the indicators displayed on the chart? That would make it much easier.
