# Flare

🔶 METHODS

• Pine Script™ introduces methods (1, 2)! Much kuddos for the developers, Tradingview, and all who has worked on it!
• This educational script will show the simplified way of writing built-in methods, not to create a new method.

🔹 Simplified way of writing built-in methods:

```
newArray = array.new<int>()
array.unshift(newArray, 1)

lin = line.new(na, na, na, na)
line.set_xy1(lin, bar_index     , close)
line.set_xy2(lin, bar_index + 10, close)

label newLabel = label.new(bar_index, high)
if barstate.islast
label.delete(newLabel)```

· We now can write it like this:
```
newArray = array.new<int>()
newArray.unshift(1)

lin = line.new(na, na, na, na)
lin.set_xy1(bar_index     , close)
lin.set_xy2(bar_index + 10, close)

label newLabel = label.new(bar_index, high)
if barstate.islast
newLabel.delete()```

——————————————————————————————————————————————————————————

· When using [1] sometimes brackets are necessary:
```
label lab = label.new(bar_index, high)
if barstate.islast
label.set_color(lab, color.red)
label.delete(lab[1])```
· ->
```
label lab = label.new(bar_index, high)
if barstate.islast
lab.set_color(color.red)
(lab[1]).delete() // lab[1].delete() doesn't compile at the moment```

🔶 OVERVIEW OF SCRIPT

• The basic principles are:
· Find 1 point (close) x bars back from current bar (settings: 'x close back').

· Create a 'Flare' shaped object from that point to current bar or further (dependable of "Width of Flare").
· Calculate where current close is located versus the Flare lines.
· On that bases, change colour and draw plotshapes.
· Below bar if current close is located in the upper part of the Flare
· Above bar if current close is located in the lower part of the Flare
· Above & Below if located in the middle part of the Flare
-> Above & Below colours has 3 different colours (adjustable), dependable on the position

🔶 EXAMPLES

· Neutral zone:

· Light Bullish zone:

· Bullish zone:

· Very Bullish / Overbought zone:

· Light Bearish zone:

· Bearish zone:

· Very Bearish / Oversold zone:

🔶 TECHNIQUES

🔹 I. Make a User Defined Type (UDT) Flare, with:

· 5x linefill - array of linefill
· int iDir, which captures the direction (current location of close in Flare)
· color cCol, this is a colour variable in relation to the direction.

🔹 II. Different functions will add a new Flare object, and update the values on each bar.

· Explanation of each function can be found in the script.

🔶 EXTRA's

· The input.color() is located in the function set_flare_B(flare obj)
· Best to put the inputs at the beginning of the script, I included this alternative just to show it is possible (but mostly not ideal)
· Background colour (settings: Bgcolor) can be enabled for better visibility of colours
