Bollinger Squeeze 3


This study calculates and displays a Bollinger Squeeze of the Third Type for the data specified by the Input Data Input.

Let \(X\), \(n\), \(v_{MA}\), and \(v_{\sigma}\) denote the Input Data, Study Length, Moving Average Multiplier, and Standard Deviation Multiplier Inputs, respectively.

This study displays two Subgraphs for \(t \geq 0\): The Ratio and the Squeeze Indicator.

The Ratio at Index \(t\) is denoted as \(R_t(X,n,n_{MA},n_{\sigma})\), and we compute it in terms of the Standard Deviation and the Average True Range as follows.

\(\displaystyle{R_t(X,n,v_{MA},v_{\sigma}) = \frac{v_{\sigma}\cdot\sigma_t(X,n)}{v_{MA}\cdot ATR_t(n)}}\)

The moving average type for the Average True Range is controlled via the Moving Average Type for Calculation Input. By default, the Ratio is displayed as a bar graph.

  • \(R_t(X,n,n_{MA},n_{\sigma}) \geq 1 \Rightarrow\) Green
  • \(R_t(X,n,n_{MA},n_{\sigma}) < 1 \Rightarrow\) Red
