The MarketAxe indicator is one of the most POWERFUL and PRECISE indicators available. Its base is derived from linear regression. Once you start seeing the small vertical lines plotting, it is signaling that the market is coming close to its bottom. Once you notice the vertical lines becoming smaller than the preceding lines, it is signaling that the bottom has taken place. As you can see by the chart below, the MarketAxe has precisely caught every bottom of the Dow ETF (DIA) over the past several months.
