xvalue error

[mballagan]

The following line of code is producing a negative value of xvalue is this possible or an error?

double xvalue = chartControl.GetXByBarIndex(ChartBars, idx);

So for example

int idx = 22861

double xvalue = -15929

Hello, thanks for writing in.

You must make sure the index is displayed on the render view. Most will use the FromIndex and ToIndex to iterate through all the visible bars:

It's returning a negative number because this bar index is lower on the X axis of the render view.

Thanks for your reply. The issue seems to occur when I add an additional timeframe to the strategy doing the rendering The additional timeframe is not used for plottting )

else if (State == State.Configure)
{
Signals = new ConcurrentBag<Signal>();

//three renko ES chart
AddDataSeries("ES 06-21", new BarsPeriod() { BarsPeriodType = (BarsPeriodType)12345, Value = 3, Value2 = 1 });
}

Are there possible issues with OnRender() with multitimeframes? I wish to plot based on the base timeframe (BarsinProgress==0)

Hello, thanks for your reply.

The ChartBars object is the primary bars series, so the second time frame should not have an effect on this. GetXByBarIndex will return negative values if the bar index is not visible on the chart at the time it is called.

Best regards.
