Renko charts have their origins in Japan where they were used during the 19th century. A Renko chart is categorised as noiseless because it eliminates insignificant price action. Also, the Renko chart is a one-dimensional chart because its plotting only takes price into account. Simplicity and objectivity are the major advantages of Renko charts. Renko is a complete charting system that is objective in nature and applicable on all types of financial instruments and over all time frames.
