I am searching 2 days for high timeframe darwins that are good. I need that diversification as well. I have found OCD and PFZ but for different reasons I have put them aside atm.
PFZ has an ugly graph and more importanly it has different amount of assets in the last year (7 vs 11 for the year prior) so in my mind I see a darwin that has 12 months of history. In any case I have it on my radar as it satisfies the criterion i like (<1d average duration in all trading assets).
OCD looks very good so far but the lack of more history and the fact that it has some assets that are trading in hours it kind of defeats the purpose.
The only I found today are.. ZXW (apart from 2 assets out of 30..) and ... YZZ. I was surprised and not surprised if you know what I mean.
