I really like the SHI Channel indicator and I think it could be very useful as part of an EA. I'm not sure if it is right for the daytrading2 EA though since the daytrading2 EA relies on opposite signals to close trades (instead of a stop loss). These opposite signals would probably often be counter to the slope of SHI.

I think it would work best on an EA that was specifically designed for the 15M timeframe, since SHI is designed for 15M charts. I would love to see it.
