Rmi

no i got it from standard indicators RMI = Relative Momentum Indicator
but here are the guts of the code

protected override void Initialize()
{
Add(new Plot(Color.Lime, "RMI"));

Add(new Line(System.Drawing.Color.Green, 30, "Lower"));
Add(new Line(System.Drawing.Color.Black, 50, "Center"));
Add(new Line(System.Drawing.Color.Red, 70, "Upper"));

avgUp = new DataSeries(this);
avgDown = new DataSeries(this);


PriceTypeSupported = true;
}

/// <summary>
/// Calculates the indicator value(s) at the current index.
/// </summary>
protected override void OnBarUpdate()
{
double amountUp = 0;
double amountDown = 0;
double rmi = 0;

if (CurrentBar ==0)
{
avgUp.Set(0);
avgDown.Set(0);

return;

}

if (CurrentBar < (Period + Shift))
{
return;
}
else if (CurrentBar == (Period + Shift))
{
double sumUp = 0;
double sumDown = 0;

for (int barsAgo = 0; barsAgo < Period; barsAgo++)
{
amountUp = Input[barsAgo] - Input[barsAgo + Shift];
if (amountUp >= 0)
{
amountDown = 0;
}
else
{
amountDown = -amountUp;
amountUp = 0;
}
sumUp = sumUp + amountUp;
sumDown = sumDown + amountDown;
}
avgUp.Set( sumUp / Period);
avgDown.Set( sumDown / Period);
}
else
{
amountUp = Input[0] - Input[Shift];
if (amountUp >= 0)
{
amountDown = 0;
}
else
{
amountDown = -amountUp;
amountUp = 0;
}
avgUp.Set((avgUp[1] * (Period - 1) + amountUp) / Period);
avgDown.Set((avgDown[1] * (Period - 1) + amountDown) / Period);
}

if ((avgUp[0] + avgDown[0]) != 0)
{
rmi = 100 * avgUp[0] / (avgUp[0] + avgDown[0]);
}
else rmi = 0;


Value.Set(rmi);
}

Hello RicRules,

Thank you for providing some of the RMI code. You would likely add the following code:

[COLOR="DarkGreen"]//....
else rmi = 0;[/COLOR]

[B]if(rmi > 50) { PlotColors[0][0] = Color.Red; }
else { PlotColors[0][0] = Color.Green; }
[/B]
[COLOR="DarkGreen"]Value.Set(rmi);
//...[/COLOR]

in the OnBarUpdate() method.

Please let me know if you have any questions or if I may be of further assistance.

[RicRules]

here is what i came up with that compiles (by itself with everything else commented out)
{
if(RMI(14,4)[0] > 50) { PlotColors[0][0] = Color.Red; }
else { PlotColors[0][0] = Color.Green; }
}

no cause nt to not open

Hello RicRules,

Please delete the code that causes NinjaTrader to not open and try the code I have provided for your RMI indicator instead.

The steps are as follows:
1. Navigate to Tools -> Edit NinjaScript -> Indicator
2. Select the RMI indicator
3. Scroll down to the following code:

if ((avgUp[0] + avgDown[0]) != 0)
{
rmi = 100 * avgUp[0] / (avgUp[0] + avgDown[0]);
}
else rmi = 0;


Value.Set(rmi);

4. Change it to look like the following:

if ((avgUp[0] + avgDown[0]) != 0)
{
rmi = 100 * avgUp[0] / (avgUp[0] + avgDown[0]);
}
else rmi = 0;
if(rmi > 50) { PlotColors[0][0] = Color.Red; }
else { PlotColors[0][0] = Color.Green; }
Value.Set(rmi);

5. Press F5 on your keyboard to recompile.
6. Add the RMI indicator to a chart.

Please let me know if you have any further questions.
