Renko with Dynamic Support and Resistance

Renko candles are a type of chart used to filter out minor price movements, focusing on more significant trends. Unlike traditional candlestick charts, Renko charts do not use time as the primary unit but instead focus on price movements, with each brick representing a certain amount of price movement, or a "brick size." When the price moves by the predefined brick size in a given direction, a new Renko brick is created.

Renko charts are useful for identifying trends and key support/resistance levels, and they help eliminate market noise. Here's a brief explanation of how Renko works:
How Renko Charts Work:

Brick Size (Box Size): The user sets a fixed value (in terms of price) that determines when a new brick will form. For example, if the brick size is 10, a new brick will appear every time the price moves up or down by 10 units.
Direction of Bricks:
If the price moves up by the brick size, a new brick is added in the up direction.
If the price moves down by the brick size, a new brick is added in the down direction.
If the price doesn't move enough to form a new brick, no new brick is created.
No Time Element: Unlike traditional candlesticks, there is no time involved in Renko charts, meaning that bricks can be formed over any period depending on the price movements.

However, since Renko is a price-based chart type and not a time-based one, the actual Renko candles are not directly supported as a visual element in Pine Script. But you can replicate the behavior by plotting the price series based on the conditions for Renko.

Renko Charts Use Case:

Trend Identification: If you see multiple consecutive green bricks, it indicates an uptrend. Similarly, multiple red bricks indicate a downtrend.
Support/Resistance Levels: Renko charts can highlight important levels where price may reverse, as significant changes in direction are visible.
