Description
The RangeBars indicator should be attached to 1-minute charts for best historical candle accuracy.
It is displayed as an overlay on the main chart so, you may want to change the chart properties to "line chart" and the "Bear Outline" color to black for better clarity of displayed bars.
The chart contains OLHC reference points so other indicators such as moving averages can be attached directly to the range bar chart.
This is a 14-day trial version. Lifetime license can be purchased >> here <<
Available Inputs
- Bar Size (number of pips)
- Maximum Bars
- Reset Open on new trading day (Yes /No)
- Bullish Bar Color
- Bearish Bar Color

2) You can only attach indicators that let you choose the "source price" value they should reference for calculations.
you can't use then e.g.Parabolic SAR or Stochastic aso. That seems to me to be a BIG disadvantage. You are not able to play the strategies in which these indicators are involved. Right?
Sorry for the delay with my answers - unfortunately I do not get any notifications about new coments.
Anyway here are the answers to the two questions above:
1) You need to provide full access rights in your robot (AccessRights = AccessRights.FullAccess), because the indicator requires them to access functions of the .NET framework.
Failing to do so will block the indicator from initializing and you will have a NULL reference instead of a reference to the median renko indicator.
2) You can only attach indicators that let you choose the "source price" value they should reference for calculations.
Please see the image file for Renko charts with MAs applied - range bars also have reference points that can be used by indicators. You need to set the "source" as one of the range bars open,low,high or close, provided that the indicator you are using lets you set this.
Hi,
I purchased this indicator the other day and it is amazing.
I have been trying to attach a Dual Stochastic to the range bars but the highs and lows of the stochastic do not match up with the highs and lows of the range bars. I think the stochastis is actually matching up with price instead. Is there any way to correct this?
Thank you
J
Hi,
Nice indicator but just a couple of questions:
1) If I set the range to 50 it only has about 20 bars going backwards
2) I'm trying to create another indicator referencing yours but I can't seem to get it displaying any data.
rb = Indicators.GetIndicator<RangeBars>(10, 100, "Green", "Red");
GoLong[index - 1] = rb.Open.Last(1);
What am I doing wrong in referencing as there are no build errors, just no data is being returned.
Thanks
