The tutorial program use BN points to set  the start and end points of the rectangles. The rectangle class is used together with several of its properties and the create class. The tutorial uses a method to create the rectangles, which is called from several places in the program. Tutorial 114 can create 5 rectangles.

The tutorial has been kept intentionally simple.

The program is available for download for a small cost or for FREE to Gold Pass members.

This tutorial was developed using TradeStation 9.5
Version: 9.5 (Update 15). I had major problems with update 14 running under Windows 10 (totally unrelated to this tutorial), with TradeStation continually crashing whenever I tried to open a workspace or to create a chart.
This tutorial uses the ExtRight property of the Rectangle class. This only became available in release 14 of TradeStation 9.5. In the video, I describe a workaround if ExtRight is not available.

Inputs

double Zone1_Lo( 2167.8), // The price level of the lower edge of the rectangle for the first rectangle
string Zone1_Color( “Blue”), // The color of the first rectangle
int Zone1_Shading( 0), // The shading pattern of the first rectangle
int Zone1_Transparency( 100), // The alpha value of the first rectangle (between 0 and 255)
