Sentiment As an Indicator

[NinjaTrader_PatrickH]

Hello randl,

Thank you for your response.

Can you provide your updated code so I may investigate this matter further?

I look forward to your response.

Thank you Patrick and thank you for your patience (believe it or not, I am taking the Script Education from Ninja, but it is slow going I guess). What you gave me worked but I cold not get it to plot. This is what I was doing for plotting:

Add(new Plot(Color.White, "MTEMA"));

But then, I had a similar statement for plotting MT and, I dont know how the interpreter can tell the difference or assign on or the other.

Add(new Plot(Color.Red, "MT"));

See the attached plot and Properties figure.

The compiler does not assign values to Plots: you do. The computer merely does whatever you ask. You assign the value to the Plot in the code, and the computer plots it.

Sentiment as an Indicator

Here is the code Patrick.

[NinjaTrader_PatrickH]

Hello randl,

Thank you for your response.

Please remove this line from the Initialize() method and re-compile your indicator:

Add(new Plot(Color.White, "MTEMA"));

[randl]

I took the line out and recompiled but no change. The first and only Parameter is "EMA 8" but there are no choices for colors or anything which is sort of strange. The only change was, the last line of the Properties window (in my previous attachment) is no longer there.

Randl,

Thank you for the reply.

Just to clarify, you are wanting to plot the MTEMA on the chart correct?

[randl]

I want to plot 2 things on the indicator:
1. The market thrust which is plotting already (in Red)
2. The Exponential Moving Average of the Market Thrust (8 being the default)
Thanks

Randl,

Thank you for the info.

You will need to set the MTEMA how you want it plot on the chart -

MTEMA.Set(EMA(mT, 10)[0]);

This will take the EMA 10 period of the Market Thrust Data Series and plot it on the chart.

You will need to also add a properties for the Plot of the MTEMA

Add this line to the Properties region of the code -

[Browsable(false)]
[XmlIgnore()]
public DataSeries MTEMA
        {
            get { return Values[1]; }
        }

This will allow you to have them setup as properties to adjust color and size in the indicators parameters window.

Let me know if this is the answer you are looking for

[randl]

Patrick, clarify for me. What are you referring to as "mT"?

The EMA URL says:

Syntax
EMA(int period)
EMA(IDataSeries input, int period)

Returns default value
EMA(int period)[int barsAgo]
EMA(IDataSeries input, int period)[int barsAgo]

So mT is probably a DataSeries, but I dont have one with that name.
Thanks for all your help.

[NinjaTrader_CalH]

Apologies, the correct one is called Values.

You would change the mT to Values[1][0]

Should look like this -

MTEMA.Set(EMA(Values[1][0], 10));

The Values will access the first plot set that you call MT or Value.Set() in the OnBarUpdate.

[randl]

Here is the code in that area:

protected override void OnBarUpdate()
{

// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
if(CurrentBars[0] <= BarsRequired || CurrentBars[1] <= BarsRequired || CurrentBars[2] <= BarsRequired || CurrentBars[3] <= BarsRequired || CurrentBars[4] <= BarsRequired)
return;
Value.Set((Closes[1][0] * Closes[3][0]) - (Closes[2][0] * Closes[4][0]));
Print(Value[0].ToString());

mTEMA.Set(EMA(Values[1][0],8)); //This is Line 61

mTEMA was defined in Variable: private DataSeries mTEMA;

And this is in the middle:
protected override void Initialize()
{

Add("^ADV", PeriodType.Minute, 1);
Add("^DECL", PeriodType.Minute, 1);
Add("^UVOL", PeriodType.Minute, 1);
Add("^DVOL", PeriodType.Minute, 1);
mTEMA = new DataSeries(this);
Add(new Plot(Color.Red, "MT"));
BarsRequired = 1;
Add(new Line(Color.Yellow, 0, "Lower"));
Overlay = false;


Here are the errors: All are from this - "Indicator\MarketThrust.cs" delete below for clarity.

1. The best overloaded method match for 'NinjaTrader.Indicator.Indicator.EMA(NinjaTrader.D ata.IDataSeries, int)' has some invalid arguments CS1502 - Line 61 Column 23

[NinjaTrader_CalH]

You won't need the [0] in the Values[1].

[randl]

Good guess but I still get:

1. The best overloaded method match for 'NinjaTrader.Indicator.Indicator.EMA(NinjaTrader.D ata.IDataSeries, int)' has some invalid arguments CS1502 - Line 61 Column 23

2. Argument '1': cannot convert from 'double' to 'NinjaTrader.Data.IDataSeries' NT1503 - Line 61 Column 27

Any other ideas?

Again, the errors tell the story. Line 61 should read:

mTEMA.Set(EMA(Values[1],8)[0]); [B][COLOR=Red]//This is Line 61[/COLOR][/B]

The Set statement requires a double; you fed it with a DataSeries.

[randl]

what does it mean "you fed it with a DataSeries."? Is that a region? if so where is it?
