My 2c, but going on the hunt to find uncorrelated trades is perhaps unproductive?
Here's the reasoning behind this....
Correlated trades imo assist to make trading easier via the fact that other correlations will flag clues as to direction, eg right at this moment USD index hit highs on a strong run up, now sitting on $99.
Gold which often has opposite correlation looks to me to be ready to move higher.
Silver too moving up. Copper and Lithium looking strong......etc
All these clues assist to make decisions on your trades.
Therefore, when hunting for uncorrelated trades, you are hunting for something which is leaving no clues.
Imo, correlations assist, 'strike while the iron is hot' in other words, one could be diversified in gold, silver, USD, copper, Lithium, all correlated but diversified.
Uncorrelation imo makes your work harder and less profitable would be my assumption.
