This is a standard 'Bulls and Bears Power" Oscillator, how ever,...
There are two different formulas for calculating bulls and bears, the standard version, uses Highest and Lowest of prices in a given period, BUT, the version we have in meta trader platform, uses the current high and current low for each bar.
Within this indicator, you can use the standard version or the meta trader version, it will draw both bulls and bears and you can turn each one on and off in the style section.
