Hello,
You will need to make a copy of the TSI that you can edit first. You can do this by going to Tools >Edit NinjaScript > Indicator > TSI > press OK> Right Click> Select Save As.. and name your indicator.

Then you can add a line within the Initialize() method. Please see the following link on how to add a line: http://ninjatrader.com/support/helpGuides/nt7/add.htm

If we can be of any other assistance please let us know.

Thanks Cody,
i know that but what i mean is adding a trace-line together with the tsi-line, see screenshot.

Hello,
You would need to add a plot that is based off of the same calculations as the signal line that you are referring to.
Please see the following link on plots: http://ninjatrader.com/support/helpGuides/nt7/plots.htm

VALUE problem ??

protected override void OnBarUpdate()
{
if (CurrentBar == 0)
{
fastAbsEma.Set(0);
fastEma.Set(0);
slowAbsEma.Set(0);
slowEma.Set(0);
Value.Set(0);

}
else
{

double momentum = Input[0] - Input[1];
slowEma.Set(momentum * (2.0 / (1 + Slow)) + (1 - (2.0 / (1 + Slow))) * slowEma[1]);
fastEma.Set(slowEma[0] * (2.0 / (1 + Fast)) + (1 - (2.0 / (1 + Fast))) * fastEma[1]);
slowAbsEma.Set(Math.Abs(momentum) * (2.0 / (1 + Slow)) + (1 - (2.0 / (1 + Slow)))* slowAbsEma[1]);
fastAbsEma.Set(slowAbsEma[0] * (2.0 / (1 + Fast)) + (1 - (2.0 / (1 + Fast))) * fastAbsEma[1]);
Value.Set(fastAbsEma[0] == 0 ? 0 : 100 * fastEma[0] / fastAbsEma[0]);
// Value.Set(slowAbsEma[0] == 0 ? 0 : 100 * slowEma[0] / slowAbsEma[0]); // don't work !!

}

Hello,
Can you clarify if you are trying to set a separate Value data series when you are doing Value.Set a second time or are you seeing that specific Value.Set overload does not work?

See variables & Initialize:

public class TSInew : Indicator
    {
        #region Variables
        private int                    fast    = 3;
        private int                    slow    = 14;

        DataSeries                fastEma;
        DataSeries                fastAbsEma;
        DataSeries                slowEma;
        DataSeries                slowAbsEma;
        #endregion

        /// <summary>
        /// This method is used to configure the indicator and is called once before any bar data is loaded.
        /// </summary>
        protected override void Initialize()
        {
            Add(new Plot(Color.Green, "TSInew"));
           [COLOR=Red] Add(new Plot(Color.Red, "TSIsign"));[/COLOR]
            Add(new Line(System.Drawing.Color.DarkViolet, -50, "Lower"));
            Add(new Line(System.Drawing.Color.DarkViolet, 50, "Upper"));
            Add(new Line(System.Drawing.Color.Red, 0, "Zero"));
            fastAbsEma    = new DataSeries(this);
            fastEma        = new DataSeries(this);
            slowAbsEma    = new DataSeries(this);
            slowEma        = new DataSeries(this);
        }

I need the signal line (fast=3) with the TSI line.
What i do, no luck.

Hello,
If you are wanting to set the second plot you would need to use Values[1].Set(). Value.Set would take over the TSI plot.
You will also need to do Values[1].Set(0) in the if(CurrenBar ==0) block.
For more information on Values please see the following link: http://ninjatrader.com/support/helpG...nt7/values.htm
