### Inside or Equals Bar

This study will color bars that have an Inside or Equals Bar pattern. An Inside or Equals Bar is a bar that has a High that is no greater than that of the previous bar, and a Low that is no smaller than that of the previous bar.

Let $$H$$ and $$L$$ be random variables denoting the High and Low prices, respectively, and let $$H_t$$ and $$L_t$$ be their respective values at Index $$t$$. Then we denote the Inside or Equals Bar at Index $$t$$ as $$IEB_t$$, and we compute it for $$t \geq 0$$ as follows.

$$\displaystyle{IEB_t = \left\{\begin{matrix} 1 & H_t \leq H_{t - 1} \space and \space L_t \geq L_{t - 1} \\ 0 & H_t > H_{t - 1} \space or \space L_t < L_{t - 1} \end{matrix}\right .}$$

The Inside or Equals Bars are the bars for which $$IEB_t = 1$$.
