The Stowell three-bar line indicator. In this indicator, the number of bars on which the lines are determined can be changed through the settings. With the default settings, the indicator draws arrows in the places where the line breaks. The lines themselves with the default settings are not displayed on the chart, but can be included.

• Alerts-enables alerts when the arrows appear. The arrows appear on the forming bar and may disappear as the bar is formed, so it is recommended to wait for the closing of the bar with the arrow to be sure that the breakout actually occurred. Accordingly, an alert can be issued for the forming bar (Alerts_Bar0) and for the first formed one (Alerts_Bar1).
• N – the number of bars by which the levels are determined.
• ShowLevels-display levels.
