rg83...the NT Support Forum is a good place to find help for ninjascript issues. Both the members and support staff are helpful. You do have to register in the Forum but you do not have to be an NT subscriber to participate.

Cheers!

You're welcome, mate. I see on the NT Forum that one of the CS techs has weighed-in.

 

Hopefully a user code guru will give you some help...either there or here.

 

Cheers!

 

Mick

 

By the way...what does the error code show when you try to compile...that screenshot of the error listing may motivate a code guru to jump in and assist (here and over there).

Thanks Mick,

 

I was trying to adjust the code from a gartley indicator but my force is **** when it comes to coding...no error when compiling it just wont plot the patterns when they show.

 

I see you are in the isle of man, in jersey myself. Do you know of any trading rooms, arcades in the islands?

Hi rg83, any luck with getting your indi working. Would like to check it out if/when you get it working.

Thanks in advance

[thaomoua]

rg83, I'm looking at your code and compilation complains that 'GartleyButterflyPatternType' does not exist. Did you leave out this enum?

[tryitagainmf]

thaouma...where would that expression of code be inserted? (since I am not a coder and do not understand what these various declarations mean)

 

Thanks, mate!

 

Cheers!

tryitagainmf, you can insert the code below line # 37 or anywhere as long as it is not inside another block of code. From the looks of the code, the missing 'GartleyButterflyPatternType' code is probably not an enum but a class that returns two properties.

 

When I created 'GartleyButterflyPatternType' as an enum, line 129, 130, 140, 141 failed because it is expecting an INT and not an enum. So what I'm thinking is 'GartleyButterflyPatternType' is probably provided by anothing indicator.

[tryitagainmf]

If I am understanding you correctly, thaomoua, we do not yet know what that line of code should look like since we would need the "other" indicator to tell this to call on?!

 

Thanks!

 

Cheers!

 

Mick

[thaomoua]

This is the code you need.

 

class GartleyButterflyPatternType {

public const int Bullish=1;

public const int Bearish=-1;

};

 

 

Place it before 'namespace NinjaTrader.Indicator'

[thaomoua]

The more I look at this code and its logic, it looks like something the indicator neoharmonic/midasTouch already do. I could be wrong though.
