Bollinger Bands with Filled Areas and Two Deviation Methods
Summary
This indicator presents Bollinger Bands as a filled area and adds a choice between sample standard deviation and uncorrected standard deviation. It also offers the usual set of 22 price types as inputs. The central idea is to make the deviation calculation configurable while retaining the familiar band framework.
The document says the difference between the two deviation methods is usually small, though it can still affect the resulting bands. It provides no formula, chart examples, performance tests, or guidance on how to use the bands to enter or exit trades. Readers therefore learn about a calculation option and display variation, but not a trading strategy or evidence that either deviation choice performs better.

- The indicator displays Bollinger Bands as a filled area.
- It lets users choose sample or uncorrected standard deviation.
- The document says the choice usually makes a small but nonzero difference.
