This post is a video post on the Optimized Renko Study that has just been released. This study lets you change your current chart to a Renko chart with the most effective brick size, with just the click of a button! You can get the study here.
Update (not in video)
For the Flex Renko chart type, there is now two ways to set the Flex Renko Trend Offset. One is fixed and the second one is using the calculation BrickSize - n; the n-value can be set.
