Multi-Series Indicator Ploting problem

[ivanov_c]

Hi I am trying to develop a Multi-Series indicator to plot MAs from two diferent time frames but the high timeframe EMA does not plot a line, it has some gaps on it.

I understand that I am using different time frames but is there anyway to plot a line without gaps?

The timeframes I am using is range bars (8) and 30 mins.

I know range bars make the X axis dinamic but I am wondering If I can have a continuos line for the 30 mins timeframe EMA plot.

Thank you

ivanov_c, welcome to our forums - could you please post a screenshot of the behavior you see?

You likely would see a so called stepping effect for the higher timeframe MA value, as there's just an updated value each 30 min bar, this then visualized on a finer frame looks like a stairstep then...thanks.

Now that you ask me for a picture I just noticed that if I try to plot a line I miss a lot of data instead of having just some gaps, I am attaching 2 graphs, one using dots and the other one using a line.

Hey ivanov,

I suspect you are trying to plot while the wrong bar is in progress or using the wrong bars series.

To get a feel for the order of the bars series do this:

protected override void OnBarUpdate()
{
if (BarsInProgress == 0)
{
Print("0");
}
else if (BarsInProgress== 1)
{
Print("1");
}
else if(......etc....

}

And look at your output window (tools>output). I found the link below confusing and the method above easeir to wrap my head around:

Thank you for your reply mountainclimber but no, I do not think that is the problem.

here is a piece of my code, I only have 2 time series, the second series is the one configured on 30 mins, the first one is the default for range 8.

protected override void OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
if (BarsInProgress == 1)
{
EMA20.Set(EMA(Close,20)[0]);
}
else
{
SlowHMA.Set(HMA(Close,slowMAPeriod)[0]);

I was expecting a continuos line but the software does not even paint a line sometimes. I just want to know if that is the expected behavior in case I cannot connect the dots with I line when some bars are missing, because of the multiple time series or if it is a bug, or a workaround.

Can you include your Initialization() block as well? If so, I'll take a closer look at it.

[ivanov_c]

Here it is:

protected override void Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Lime), PlotStyle.Line, "SlowHMA"));
...
Add(new Plot(Color.FromKnownColor(KnownColor.Brown), PlotStyle.Line, "EMA20"));
Add(PeriodType.Minute,30);
...
}

Hello,

So you are trying to plot the 30 min ema on a smaller timeframe? This worked on a 1 min. time frame, but didn't test it much and did it in 5 min's:
if(BarsInProgress == 0)
{
SlowHMA.Set(HMA(Close,10)[0]);
EMA20.Set(EMA20[1]);
}
elseif(BarsInProgress == 1)
{
EMA20.Set(EMA(Close,20)[0]);
}

In the screen shot you will see the orange lines are plotted on the chart via the chart UI for verification that the value I am plotting is accurate...and it seems to be.
