MACDBBLines

[NinjaTrader_Ray]

I see. Unfortunately this indicator you speak of is not a NinjaTrader indicator so I can't provide support for it since I don't know how this indicator operates and if you can even check for the condition you speak of. You would need to go back to the author of the indicator and ask them.

thanks Ray for looking at it, for more infor please look at eSignal Central Forum. that was written using the Formula Wizard.

When I was trying to figure out how MACDBBLines worked, I added a few, sparse comments to it that may help.

It's not up to my usual level of commenting, but it still may help.

I've attached a copy for your perusal.

How do I access the comments as they only show a snippet on the indicator?

I'm not sure I understand the question.

The comments I was talking about are embedded in the source code. A source code comment in C# (or NinjaScript) begins with "//" and runs to the end of the line.

For instance, the following line shows one of the comments that I added to MACDBBLines.cs:

// Draw a big yellow dot over the zero line intersection.

A comment is not understood by the source code compiler and is ignored (has no effect on the operation of the program.)

A comment's only use is for notations by the programmer for later reference by himself/herself or others who are trying to understand the code.

To view the code and see these comments you will need to open up the indicator source file. This can be done by going through the NinjaScript editor.

Tools->Edit NinjaScript->Indicator->select the indicator file->Open

Hi Josh
I have a no programming experience could you provide a sample script or code with “BB Macd”, so I can incorporate it into my script for backtesting . I tried the wizard with no results.
I would greatly appreciate it

[NinjaTrader_JoshP]

Sorry gary9. I am unfamiliar with how a trader would use the MACDBB to trade so I would not be able to generate a worthwhile sample for its utilization.

Here are some brief examples of how you would call Gumphrie's MACDBBLines indicator though. You will need to figure out workable trading conditions on your own.

if (CrossAbove(MACDBBLines(12, 10, 26, 5, 1).BB_UpperBand, 0, 1))
{
     // Do something
}

MACDBBLines(12, 10, 26, 5, 1).BB_UpperBand

is one of the lines and the other line is [/code]MACDBBLines(12, 10, 26, 5, 1).BB_LowerBand[/code]
To get their individual values and compare them to something you could do something like

if (MACDBBLines(12, 10, 26, 5, 1).BB_UpperBand[0] > someThresholdValue)
{
     // Do something
}

Hope that helps.

I think the code here is virtually identical, if not the same, to the code I used to create MACDBBLines.

Josh or Gumphrie,

How would I code the MACD (dots) for when they were (started) inside the upper and lower bands and then closed above the .BB_UpperBands? to enter a long and then exit the long when it closed back inside the .BB_UpperBands?. Visa versa for a short?
I tried using your examples below but just cant figure out how to code the MACD cross above/below or the greater/less than the BB_UpperBands or BB_LowerBands.

if (CrossAbove(MACDBBLines(12, 10, 26, 5, 1).BB_UpperBand, 0, 1))
{
// Do something
}

OR

if (MACDBBLines(12, 10, 26, 5, 1).BB_UpperBand[0] > someThresholdValue)
{
// Do something
}

I tried some things like:
if (bbMacd[0] > MACDBBLines(12, 10, 26, 5, 1).BB_UpperBand[0])
{
// Do something
}

and cant get anything to compile.
Any help would be apreciated.

Thanks

{

and cant get anything to compile.

bbMacd is an internal Dataseries variable to the indicator, to get that value in your code you would call the MACD directly.

[KBJ]

And here's how you'd do that.

Try this equivalent code...

double UpperBand = EMA(MACD(10,26,5),12)[0] 
              + StdDev(MACD(10,26,5),12)[0];

if (MACD(10, 26, 5)[0] > UpperBand)
{
   // Do something
}

My apologies, I was a little too quick with the solution there.

Check it again, I've corrected the error in my earlier post. (And this time I test-compiled it.)

Hi KBJ

Thanks for the code.
I'm trying to duplicate the MACDBB in the MACDBBLines indicator.
i added
&& MACD(10, 26, 5)[1] < UpperBand)
but the action was off. Apreciate further progress in making this a automated trading strategy.
