I could use help for building my own

Yes, I could use help for building my own, take into consideration that my programing skills are not even basic.

Searching the internet i fount that there is one indicator with these characteristics, but is for metatrader.

Hello Joaqvil,

I've split your post into a new forum post where we can discuss indicator development.
The original thread is linked below.

Below I am providing a link to a forum post with helpful information on getting started with C# and NinjaScript.

By 'the max percentage distance from the MA to the price' you are wanting a variable that stores the greater of two values using Math.Max() either the value currently stored by the variable or the Math.Abs() of the MA minus the Close[0] price.

A similar approach is used in this example to store the highest value.

To make this a percent you could multiply by 100.

To make an average you could save the values to a Series<double>.

And use this as the Input series to the SMA.

Or List<double>.

And use list.Average().

Or you could loop through the collections and do custom calculations.
