Looking reference for System

Hello,
i'm looking reference for a EA System that has one of the following strategies:
- Averaging
- Pyramiding
- Hedging
- Grid

I think Firebird is using Averaging system if i'm right.. and Turtle is using good Pyramiding for strong trend... Please let me know what you think a reliable system for above list.

Thanks

maybe this can help u
