### Range Bar Predictor

This study calculates and displays the projected High and Low for Range Bars. The Range Bar types are selected via Chart >> Chart Settings >> Main Settings >> Bar Period Type. The Renko Bar types are listed below. They can only be used on Intraday Charts.

Let $$H_t$$ and $$L_t$$ denote the High and Low Prices, respectively, at Index $$t$$. Let $$r$$ denote the Setting for the Range Bar (controlled via Chart >> Chart Settings >> Main Settings >> Setting) and let $$s$$ denote the Tick Size.

We denote the Predicted High and Predicted Low Prices at Index $$t$$ as $$H_t^{(P)}(r,s)$$ and $$L_t^{(P)}(r,s)$$, respectively. These are calculated for the last chart bar only as follows.

$$H_t^{(P)}(r,s) = L_t + r \cdot s$$
$$L_t^{(P)}(r,s) = H_t - r \cdot s$$
