Ever heard traders throw around the word "Cable" when talking forex? Here's the story behind it. Back in the day, the first transatlantic communications cable—the one that literally ran under the ocean via Scotland—revolutionized how traders could execute deals on the USD/GBP cross. That undersea connection was the game-changer for rapid quote transmission and order execution between American and British markets. So when FX folks mention Cable, they're basically paying homage to the physical infrastructure that made modern currency trading possible. It's a reminder that financial markets have roots deeper than most realize—sometimes quite literally wired across continents.
