Use renko graph with the options:
Creates from: Tick
Show wicks: True
New box when breaking: false
The problem is that if you select 5 days ago and compare with 20 days ago the graphic is with different boxes. This occurs in the Brazilian market; Using WINJ18.
Another problem that also occurs even with a database downloaded ticks is that it does not load the backtest with renko created from: Tick.
I await a solution!
