Converting TVJS overlay to NavyJs with ChatGPT-4 (approx). Prompt Template.

gistfile1.txt

I need to convert trading-vue-js overlay to my new .navy language. Let me show how it should look:

```navyjs
// Navy ~ 0.1-lite
// <ds>Description</ds>
[OVERLAY name=OverlayName, ctx=Canvas, verion=1.0.0, author=GPT4]
// Define new props (types: number, string, boolean, object ...), e.g.:
prop('color', { type: 'color', def: '#31ce31' })

// Local Variables (those defined in data() function), e.g.:
let A = null 

// Draw function 
draw(ctx) {
    // this.$props.layout => $core.layout
    // this.$props.data => $core.dataSubset
    // t2screen => time2x(t) 
    // $2screen => value2y($) 
    // Access props: $props.color
   
}

// mouseup, keydown, keypress, etc.
mousedown(event) { }

// Returns array of [value, color] pairs
legend() => []

```

The overlay i need to port: 

```tvjs
<Your TVJS overlay>
```

All computed stuff should be converted to props. Ignore `use_for` and `calc`. `sett` is a reference to props object, ignore it too. It's a hypothetical script, but try to implement all methods. Please don't explain, focus on code.
