Drawing a line

[kiro1000]

Hello,

I'm trying to draw a line as outlined in the NinjaTrader manual https://ninjatrader.com/support/helpGuides/nt8/NT%20HelpGuide%20English.html?draw_line.htm

However, when I attempted to compile the code, I encountered errors stating : "resource does not contain a definition for NinjaScriptIndicatorDescriptionONELINE" and "resource does not contain a definition for NinjaScriptIndicatorNameONELINE."

Any assistance in resolving this issue would be greatly appreciated

Thank you

Hello kiro1000,

The language resource dictionaries are used to translate to other languages.

The resource dictionary does not have key for NinjaScriptIndicatorDescriptionONELINE or NinjaScriptIndicatorNameONELINE.

You will need to use your own string instead.

Hello Chelsea,

Thank you for your guidance. I followed your instructions, but unfortunately, I'm still encountering the same errors. Appreciate your assistance.

here the updated code

Hello kiro1000,

The effected code is the same in post # 3 as it is in post # 1 and the direction was not followed.

Description = NinjaTrader.Custom.Resource.NinjaScriptIndicatorDe scriptionMYOWNSTRING;
Name = NinjaTrader.Custom.Resource.NinjaScriptIndicatorNa meMYOWNSTRING;

NinjaTrader.Custom.Resource.NinjaScriptIndicatorDe scriptionMYOWNSTRING doesn't exist.
NinjaTrader.Custom.Resource.NinjaScriptIndicatorNa meMYOWNSTRING doesn't exist.

Use your own string as directed in post # 2.


Description = "My description here";
Name = "Name of my script here";

[kiro1000]

Hello Chelsea,

I appreciate your guidance on using my own string for the indicator description and name. However, I encountered a challenge while updating the code. All the indicators I've come across in the NinjaTrader Library follow a specific naming convention, as shown in the examples below:

SUM indicator
public class SUM : Indicator
    {
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description                    = NinjaTrader.Custom.Resource.NinjaScriptIndicatorDescriptionSUM;
                Name                        = NinjaTrader.Custom.Resource.


**********
VOL Indicator
public class VOL : Indicator
    {
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description                    = Custom.Resource.NinjaScriptIndicatorDescriptionVOL;
                Name                        = Custom.Resource.NinjaScriptIndicatorNameVOL;

*************​

I've updated the code as per your instructions, modifying the name because I couldn't find information about the description in the NinjaTrader manual. However, I encountered an error: "Cannot convert method group 'ONELINE' to non-delegated type 'string'. Did you intend to invoke the method?"

Any assistance in resolving this issue would be greatly appreciated.

Thank you.

Hello kiro1000,

As mentioned in post # 2, NinjaTrader has a resource dictionary to translate our system indicator names and descriptions to other languages. Our resource dictionary does not have your custom translations.

Your class is ONELINE. This is not a string.

A string is text between quotation marks.

See post # 4 where I have suggested using strings (not the class object).

Description = "My description here";
Name = "Name of my script here";

[kiro1000]

Hello Chelsea,

I apologize for any confusion earlier. I've successfully compiled the code after implementing your suggestions and using strings for the Description and Name. However, I've encountered an issue where the dotted line is not being plotted as expected.

Hello kiro1000,

On each new bar the object is moved to the last bar (as you are not using unique tag names.

The line is being drawn at a price of 1000 which is not in range of the price scale. I recommend you set isAutoScale to true so that you can see where this is being drawn.

However, despite these changes, I'm still unable to see the line being drawn on the chart.
Thank you for your continued support.

Hello kiro1000,

After making changes may I confirm you have compiled and reloaded the script?

May I have an updated screenshot with the chart showing the last bar on the chart?

[kiro1000]

Hello Chelsea,

Yes, I have compiled the script and reloaded it into NinjaTrader. Here is the updated screenshot with the chart:

[NinjaTrader_ChelseaB]

Hello kiro1000,

The line is drawn at 17800 and is below the price range of the chart.

Click the F to return to autoscaling and it should be at the bottom of the chart.

[kiro1000]

Hello Chelsea,

Thank you for your continued assistance. I recompiled the code, added it to the chart, and clicked on the F to return to autoscaling, but unfortunately, the line is still not appearing at 17800.

Here is the updated screenshot with the chart:

Hello kiro1000,

May I have an export of the test script to test on my end?

Once exported, please attach the file as an attachment to your reply.

[kiro1000]

Hello Chelsea,

Certainly, I appreciate your willingness to assist. I have exported the test script as instructed. Here is the attached file named "OneLine.zip"
