Is there already script somewhere here for 2 EMA crossovers?

So title yours how you want them to be in Properties. What ever you name it in the line I have highlighted in Properties is what you have to call for the .Set.

This is how properties now reads, but I get an error that '}' expected on the line in red below in col 16 but it doesnt fix it when added :
#region Properties
///<summary>
///</summary>
[Browsable(false)]
[XmlIgnore()]
public DataSeries Fast
{
get { return Values[1]; }
}
///<summary>
///</summary>
[Browsable(false)]
[XmlIgnore()]
public DataSeries Slow
{
get { return Values[0]; }
}

#endregion

[simpletrades]

this how variables reads:
#region Variables
privateint fast = 5;
privateint slow = 6;

#endregion

and this is above properties:
Value.Set(CurrentBar == 0 ? Close[0] : Close[0] * (2.0 / (1 + fast)) + (1 - (2.0 / (1 + fast))) * Value[1]);
Value.Set(CurrentBar == 0 ? Open[0] : Open[0] * (2.0 / (1 + slow)) + (1 - (2.0 / (1 + slow))) * Value[1]);

simpletrades,

You likely have some missing parenthesis or curly brackets above that line somewhere which makes all downstream editing erroneous.

Again, you should NOT be using Value.Set. You need to call .Set on the actual plot names that you have defined. Please look at the relationship between all the parts at play in MACD. Look at the Initialize() how the Add() creates the plots. Look in the Properties how the plots names are created. Then look in OnBarUpdate() for how .Set is actually used on each one of them.

I had replaced Value with Fast and Slow but got more errors so I switched back to Value, but I'll redo it again and try to find the unmatched }

[simpletrades]

still stuck. I tried to copy what looked like it was needed out of MACD.
I get an error now that there is no definition for plots (as shown below):

fastEMA.Plots[0].Pen.Color = Color.Orange; slowEMA.Plots[0].Pen.Color = Color.Blue;

Here's my current code:

simpletrades, you have commented out 'Add Plots' section in your Initialize(), so you can't customize those later - you would also need to refer to both plots individually to change the colors as you like to...

 
Add(new Plot(Color.Orange, "Fast")); 
Add(new Plot(Color.Blue, "Slow"));
 
Plots[0].Pen.Color = Color.Orange; //EMA(Fast)
Plots[1].Pen.Color = Color.Blue;//EMA(Slow)

I thought the pairs were mutually exclusive--one pair of orange-blue or the other.
i'll try it. thanks.

I had an Indie Ninja provided me with an EMA crossover, that also painted the bars. Cyan or Lime if 5 ema crossed above 89 ema, or red if 5ema crossed below ema. With new version of Ninja 7 I can not find it. does anyone have the .zip indie file?? Thanks!

Hello Scottiep,

I'm not familiar with this indicator and does not sound like one that is on our forums or included with NinjaTrader.

Can you remember the name of the indicator so that I may search for it?
