In this version, I have greatly improved the interface to make it more user friendly. Previously, it had separate buttons for closing or partially closing buys and sells. Now, this is done with only one set of buttons instead of two.
Also, in the previous version, you could only move the interface around through the use of tabs on each edge. This was very cumbersome. In this version you can actually drag and drop each of the four canvases to move the interface around on the chart and locate them where you like. Furthermore, I have made it record the last location in Global variables so that when you start the tester again, it will have the interface arranged the way that you left it.

I had a canvas rectangle behind the buttons that was on the same zorder as the buttons and was causing some selectibility conflicts. Also the canvas rectangle was selectable so I set it's selectability to false.

Some were having trouble seeing the text on the chart because they were using a black chart and the default black text.. I put a check in the program to detect when the chart background was black as well as the text. If the text was still black on a black chart, it will change the text to white.
