Gann grind is a set of 45 degree lines plotted over a price chart for an instrument. Whenever the price stays above one of these ascending lines (better if it touches it in one or more points) the instrument is on a strong bullish movement. And whenever the price stays below one of these descending lines the instrument is on a bearish movement. When intersection of one line occurs it is considered that the basic trend is broken, and when the price intersects more than one line it is considered as the beginning of a new trend.
