Absolutely, i would go for CCY and trading detail (time, lenght, PnL). Those are good representative variables to take a look to.
From a quantitative viewpoint, a good strategy on a given ccy is a stacked one which averages different views on the ccy, translated into a PnL (either materialiazed or marked-to-market). Such view is an aggregation of decisions that, backtested and regularized, proved to be better. Stacking is good for the trader because it could net offsetting positions, saving pips that would otherwise go to the broker.
Then, from a darwinex investor viewpoint, I would pay those pips for really diversifying my risk if that outweights the market risk of the selected darwins.
