This document describes a trading strategy called "Follow the Leader" that capitalizes on correlated currency pairs. It explains that some currency pairs, like the EUR/USD and GBP/USD, typically move in the same direction due to shared fundamentals. The strategy looks for times when one currency pair's price range lags behind the other, indicating they have fallen out of correlation temporarily. It then enters a trade, betting the pair with the smaller range will catch up to match the larger range of the other, resulting in profitable movement back into correlation.
