Test coherence results across independent data venues

Extend each asset-class panel to a second independently sourced venue to determine whether venue-specific quoting, liquidity, or market-microstructure artifacts contribute to the reported cross-panel differences.

Background

Only the two cryptocurrency panels are observed through independent data sources and agree in sign and approximate magnitude. Each remaining asset class is represented by a single provider, so provider-specific quoting and liquidity effects may contribute to the observed differences across asset classes.

A second independent venue for every panel would provide the most direct test of whether the reported coherence relationships and asset-class split are robust to data-source choice.

Finally, with the exception of the two independently-sourced cryptocurrency panels (Binance and the broker CFD feed, which agree in sign and rough magnitude), each asset class here is observed through a single provider, so venue-specific quoting or liquidity artifacts cannot be ruled out as a partial driver of the cross-panel differences reported; extending every panel to a second, independently-sourced venue, the way the cryptocurrency panel already is, would be the most direct way to close that gap.
