The indicator helps:

• Buy at swing-lows of the uptrend
• Sell at swing-highs of a falling trend

The indicator draws three elements on the chart. Trend, extremes, and notification arrows.

The trend and extremes are equal to values from -100 to 100, depending on the indicators of the combination of indicators.

The values show how strong these two elements are.

The notification arrows are shown when Trend and Wave are opposite, indicating the possibility of trading.

• Down trend: red, negative values

Extremes: shown with “x” characters. Shows how much the instrument is oversold/overbought

• Overbought: red color, positive values, a good opportunity to make a sale, at this time it is not worth buying
