Disliked...dynamic Renko Bars...idea of controlling the size of the bar with an ATR...Ignored
Consider the pic, even for historical blocks, everything is fine when the block is fixed size, but if the blocks are based on an atr(say period 1) value, then the blocks would be redrawn+resized to include or exclude any candle. The atr values in the pic have levels in multiples of 10pips, so you have 1x and *2x block heights, and the renko blocks are 20pip, Its constantly switching block height. Guessing what it may look like, redrawing them would probably make everything look erratic.
I'd rekon to get an idea of what some sort of atr based block thing would look like, load a supertrend indicator, or a step ma, both vary with atr.
