Code for nice graphical panel displaying values of my custom indicators in the chart window

I need a developer to write the code for creating a nice visual panel on the chart to help while I’m conducting tests. The panel will display the values of my custom indicators in a box on the chart, so I will need you to integrate your code for developing the visual panel with my code which calculates the values of the indicators and stores them in variables of the type int, double or bool.

If you apply to do the job, please attach a visual example of the kind of panel you propose to develop for me.

I want a panel that is capable of hosting and displaying in an aesthetically appealing way around 20 indicators.

Important: the panel needs to work / display properly also in the Strategy Tester.

I do not need any alerts, I just the visual in the chart window.

I do not need to move the panel with the mouse, I just need the panel to occupy about 20-25% of the chart, and be placed on the left side of the chart.

I will need to add more indicators later, so you will have to make it flexible and explain to me (in good English) how I can easily add new indicators when I will need to do so, without complicating the code.

I will need this updated later on and integrated with other code, so if you do a good and quick job, we will have a longer collaboration.
