The Universal indicator by John Ehlers plotted directly on the chart, for an immediate understanding of its state. It has been implemented with the moving average of the oscillator, the overbought and oversold areas, and the colors indicating the direction of the trend. Suitable for any chart and time frame.

Indicator interface

• OVERBOUGHT = change the level of the Overbough line;
• OVERSOLD = change the level of the Oversold line;
• UNIAVG = enables or disables the moving average applied to the value of the Universal oscillator;
• UNIAVGPERIOD = changes the period of the moving average applied to the Universal oscillator;
• UNIVERSALPERIOD = changes the oscillator period;
• UNIVERSALFILTER = change the indicator filter period;
• TIGHTENCHANNEL = change the channel width;
• ATRPERIOD = changes the calculation period of the ATR used for the formation of the channel, serves to optimize the channel size;
• AVERAGEPERIOD = changes the value of the moving average used for the formation of the channel;
• AVERAGEMETHOD = is used to select the type of moving media used for the formation of the channel.

How it can be used:

1. As a trend indicator;
2. For inversion strategies;
3. As a channel, to identify the range of market movement;
4. As an entry and exit signal, when the Universal value crosses the level 0, or crosses the overbought and oversold levels, or its moving average;
5. Within automatic trading strategies, such as entry, exit or as a filter.
