Relative strength and breadth analysis are less explored methods in trading. However, a combination of these two tools can complement any price-based trading system and help improve the overall profitability of the system.

This book explains an entirely different way of looking at the markets. You will also learn objective methods that will assist in achieving returns that is better than the broader market.
