    Stacked 1 Range Chart Style as a 30 Minutes Bar

    I need to plot a 30-minute chart of the ES with range bars. My target is to break each 30-minute candle by the tick.
    The problem is that there is no such Chart Style, so I have to figure it out somehow.

    My goals is to apply this new Range Style to an ES 30-minute chart, but with eack range bar stacked upon each other until they complete the 30-minute timeframe instead of creating a new bar with a higher Time.

    I newer approached creating a new Chart Style, nor adapting an existing one. So, I cloned the PriceBox Chart Style for a start. I tried to see how to proceed, got stuck, messed it up, and finally left it alone. The internal code of a Chart Style seems to be far too advanced for my current coding skills.

    I understand that the Time value of each bar has a role in the final solution, but I don't understand how to fit the logic to control this. Let alone what logic.

    Any hint about how to approach such a task.?

    Hi Gianpiero, thanks for posting. If you want to create your own bar types or chart styles, I can only recommend fully understanding and studying the bar type and chart styles that are in the platform by default. This post will remain open for other forum members to contribute their ideas and experience on the subject.

    Kind regards,

      Hello ChrisL, Thanks for your reply. I looked more closely into the BoxStyle class code, and I guess I figured out where to update it.

      Just one more little help. This is a snippet of the actual @BoxStyle.cs:
      Code:
              protected override void OnStateChange()
              {
                  if (State == State.SetDefaults)
                  {
                      Name            = Custom.Resource.NinjaScriptChartStyleBox;
                      ChartStyleType  = ChartStyleType.Box;
                      BarWidth        = 1;
                  }
      ​
      I guess I have to set the ChartStyleType parameter to something else since I doubt I can mess with ChartStyleType.Box.

      Looking around, I found this kind of assignment, too, that I do not fully understand:
      Code:
                  if (State == State.SetDefaults)
                  {
                      Name = "TestStyle";
                      ChartStyleType = (ChartStyleType)58;​
      Is it the preferred way to declare ChartStyleType? What about the number 58? I surmise it has to do with an enumerated structure in NinjaScript. The only thing I know about it is to pick a high number to avoid collision with built-in values. Is that so?

        Hi Gianpiero, thanks for the follow up. It is recommended to just choose a high number that is far away from the 8 default chart style types. We have a related example here that identifies bars types:
