Bulls Power - traditional general approach

Bulls Power is used to estimate power of the Bulls (Buyers). Bulls Power estimates the balance of power between the bulls and bears. This indicator aims at identifying if a bullish trend will continue or if the price has reached a point where it might reverse. A buy signal is generated when the Bulls Power oscillator moves above Zero. In an up trend, the HIGH is higher than EMA, so the Bulls Power is above zero and Histogram/Oscillator is located above zero line. Exit Signal: if the HIGH falls under EMA then it means that price are starting to fall, the Bulls Power histogram fall below the zero line.
