Renko series in technical analysis is designed to filter out minor fluctuations in price data by focusing solely on significant price movements. Unlike typical charting methods that consider time and volume, Renko charts are only influenced by price changes. Each brick in a Renko chart represents a movement in price up or down by a predefined amount, known as the brick size or box size. Bricks are placed in the next column only when the movement in the price is opposite to the direction of the previous brick, effectively highlighting trends and reversals.

This series requires a `[Date, Close Price]` format data and all of the calculations are done under the hood.
