What is Bear Power(Bulls Power) indicator, the instructions of Bear Power(Bulls Power) and how to use the Bear Power(Bulls Power) indicator, the calculation of Bear Power(Bulls Power) indicator and the Bear Power(Bulls Power) indicator main parameters

## Introduction

Elder-Rays Technical Indicator combine the properties of trend following indicators and oscillators. They use Exponential Moving Average indicator (EMA, the best period is 13) as a tracing indicator. The oscillators reflect the power of bulls and bears.To plot the Elder-Rays three charts should be used: on one side, the price chart and Exponential Moving Average will be plotted, on two other sides bulls power oscillator (Bulls Power) and bears power oscillator (Bears Power) will be plotted.

Elder-rays are used both individually and together with other methods. If using them individually, one should take into account that the Exponential Moving Average slope determines the trend movement, and position should be opened in its direction. Bulls and bears power oscillators are applied for defining the moment of positions opening/closing.

## Trading rule

Buy if:

- there is an increasing trend (determined with the Exponential Moving Average movement);
- the Bears Power oscillator is negative, but increasing at the same time;
- the last peak of the Bulls Power oscillator is higher than the previous one;
- the Bears Power oscillator increases after the Bulls divergence.

At the positive values of the Bears Power oscillator, it is better to keep back.

Sell if:

- there is a decreasing trend (determined with the Exponential Moving Average movement);
- the Bulls Power oscillator is positive, but decreases gradually;
- the last trough of the Bulls Power oscillator is lower than the previous one;
- the Bulls Power oscillator decreases leaving the Bears’ divergence.

Do not open short positions when the Bulls Power oscillator is negative. Divergence between the Bulls and Bears Power and prices is the best time for trading.
