Pine Script - 价格/ATR 不正确

Question

问题一 我正在尝试用股票收盘价除以 ATR 来表示自己的比率。 手算显示一个数字，但代码中的数学显示另一个数字。

显然我遗漏了一些东西，但我不知道是什么。 可能真的很简单，但我是新手，正在努力通过。

Price / ATR = Var1

Hand calc Ex: 
NVDA on Fri Mar 17, 2023 
Price = 257.25
ATR = 10.02
Var1 = 25.6

The script is showing Var1 = 12.86

（不是我的剧本，而是改变别人没有的东西。站在他们的肩膀上）

Improvement 1:
After the math is figured out, I'd like to add an If Then statements.

Output < 20 = color1
Output > 20 and Output < 30 = color 2
Output > 30 and Output < 40 = color 3
Output > 40 = color 4
