Modify a utility to my needs

Hello,

I would need the following indicator/utility to be modified. I do not know if certain things are possible or not.

Please let me know.

Here is the base utility: https://www.mql5.com/en/code/8016

What I would need:

Additional lines that are offset to the inside on both sides by an ATR period (300) multiplied by X in points. These values should be accessible via the inputs tab.

(See the attached screenshot. I marked an example by hand with thicker lines).

Now the tricky part:

When the "channel" is lower than a certain angle, let us say we are in an uptrend, but the angle of the channel is less than 30°, all lines

are drawn in a different style. Same for the sell side. If the angle is larger than -30° all lines are drawn in a different style.

I would like to have the ability to define this angles range within the inputs tab. Maybe something like Start and End range in degrees. For the above

example the input would be like Start->30° End->-30°. Let me know if it is possible. I would like to hear your direct opinion during the application

for this topic. (See the attached example that I put in by hand as well.)

Last but not least. All parameters like visibility, color, style for each line should be accessible via the inputs tab.
