Forex Sentiment Flip
Lists any major currency whose sentiment polarity flipped (positive ↔ negative dominant) since the prior reading.
// The Problem
What this recipe solves
Sentiment reversals on the majors often lead price around rate decisions, but watching seven currencies by hand is tedious. This script checks them all in one pass and only speaks up when one flips.
// The Script
