### Wide Range Bar

This study highlights chart bars that are wider than any of the prior bars in a specified lookback period.

Let the Open, High, Low, and Close Prices at Index \(t\) be denoted as \(O_t\), \(H_t\), \(L_t\), and \(C_t\), respectively. Then we denote the Range of Current Bar at Index \(t\) as \(RCB_t\). \(RCB_t\) is calculated for \(t \geq 0\), and the method for calculating it depends on the value of the Input **Use Open To Close Range Only**.

If **Use Open To Close Range Only** is set to Yes, then \(RCB_t = |O_t - C_t|\).

If **Use Open To Close Range Only** is set to No, then \(RCB_t = H_t - L_t\).

Let the Input **Number of Bars to Compare** be denoted as \(n\). This Input plays the role of a **Length**. Then we compute a value called Wide Range for each chart bar, and we denote its value for the given Input \(n\) at Index \(t\) as \(WR_t(n)\). We compute \(WR_t(n)\) for \(t \geq 0\) as follows.

For \(t = 0\): \(WR_0(n) = 1\)

For \(t \leq n - 1\): \(WR_t(n) = \left\{\begin{matrix} 1 & RCB_t > \max\{RCB_0,...,RCB_{t - 1}\} \\ 0 & RCB_t \leq \max\{RCB_0,...,RCB_{t - 1}\} \end{matrix}\right .\)

For \(t > n - 1\): \(WR_t(n) = \left\{\begin{matrix} 1 & RCB_t > \max\{RCB_{t - n},...,RCB_{t - 1}\} \\ 0 & RCB_t \leq \max\{RCB_{t - n},...,RCB_{t - 1}\} \end{matrix}\right .\)

The bar with Index \(t\) is highlighted if and only if \(WR_t(n) = 1\).
