Renko Chart MT4
Renko Chart MT4 creates an autonomous Renko chart where all bars are shown as Renko "bricks" with no wicks. The size of the "bricks" is specified in the settings.
The autonomous Renko chart is displayed not only on history, but also online. The chart is updated at least every three seconds.
