Ergodic Oscillator & Center of Gravity
The Ergodic Oscillator is a technical indicator used to identify trend reversals in financial markets. It's calculated by taking the ratio between two moving averages of the price, and then smoothing the result with an additional moving average.
The Center of Gravity indicator is another technical indicator that attempts to identify potential turning points in the market. It uses a weighted moving average to determine the center of gravity for a given period, and then plots the difference between price and the center of gravity.
By combining these two indicators, a trading strategy can be designed to generate entry and exit signals.
This example strategy is machine generated using Gunbot AI. Review its behavior carefully in a simulated bot instance before using parts of this code in production.
