Tips for directional bias during Asian Session?

I have a price model I've been refining the last 2 quarters during the Asian session and my only drawback is that I don't have a predetermined directional bias during the Asian session (8pm eastern to 10pm Eastern) or I feel as if I don't.

I only use the 10year yield and the Dxy to help me and I trade solely Xauusd and have been gathering data for Audusd as of late.

Any tips would be greatly appreciated.

How is your pricing model travelling? Was it successful, have you made it work?
