Your DAX renko chart looks really clean, what settings and indicator are you using to generate it?
that one was the MathsTrader7 ea (see post above), set on 'non-gap' 3 tick (30 point) so the reversal bars are twice that (6 tick). Might be a bit too fast for some, the chart above only covers 30 minutes though it was during very high volatility on the London open today.
The levels are #SpudFibo, I also use Auto Pivot2 and Fractal S/R.
The RSI MA I'm just experimenting with.
