The Highest and Lowest indicators return the highest/lowest values in a data series over the specified period.
Highest highest20BarHigh = new Highest(bars.High, 20);
Highest highest200BarHigh = Highest.Series(bars.High, 200);
Lowest lowest20BarLow = new Lowest(bars.Low, 20);
Lowest lowest200BarLow = Lowest.Series(bars.Low, 200);
For each trading period, the Highest indicator returns the highest data point in the specified period, while the Lowest indicator returns the lowest data point. Like any Quantacula indicator, you can pass any BarHistory component such as Open, High, Low, Close or Volume as your source parameter. You could also pass another indicator or TimeSeries instance as the source.
Use the slider to change the period that the Highest and Lowest determination is based on. The chart will update dynamically as you slide the slider.
