Future value indicator

[gviand]

Hello,
How could I know the value of any indicator if the price of the current bar closed, for example, with a value of 20 ticks higher? Example: what would be the value of ema(close, 14) if the price of the current candle was 20 ticks higher? Is there a way to program it in ninjascript?

Hello gviand,

Thanks for your post.

You could consider creating a Series<double> variable named something like myDouble and assign the Close[0] price plus 20 Ticks to this variable.

Then, you could pass this variable in for the Series<double> input argument when calling the EMA() method and assign this value to a plot.

//class level variable
private Series<double> myDouble;

//OnStateChange
if (State == State.SetDefaults)
{
    AddPlot(Brushes.DodgerBlue, "Plot1");
}
else if (State == State.DataLoaded)
{
    myDouble = new Series<double>(this);
}

//OnBarUpdate
protected override void OnBarUpdate()
{
    myDouble[0] = Close[0] + 20 * TickSize;

    Values[0][0] = EMA(myDouble, 14)[0];
}

See the attached reference sample demonstrating this.

And, see the help guide documentation below for more information.

Let me know if I may assist further.

Thanks for your reply. What I need is something different. I need to calculate what would be the value of EMA(Close, 14) considering only that the current candle was 20 ticks higher, leaving the previous candles with their original close. That is, I need to simulate the value of candle number 0.

Hello gviand,

Thanks for your note.

This would go beyond what we would be able to provide support for. It would require you to program your own custom calculations within the script to determine what the EMA value might be if only the currently forming bar is 20 ticks higher. A Series<double> input must be used when calling EMA() as seen in post #2. It would not be possible to change a single candle's value for the EMA indicator to calculate.

This forum thread will be open for other community members to share their insights on possible custom calculations to accomplish this.

Let me know if I may assist further.
