About Net change

[NinjaTrader_ChelseaB]

Hello ラリー,

As a heads up, you cannot copy and paste code from a screenshot.

Copy and pasting the few lines of code or sharing an exported script allows the receiver to use the code.

To export a NinjaTrader 8 NinjaScript so this can be shared and imported by the recipient do the following:

1. Click Tools -> Export -> NinjaScript...
2. Click the 'add' link -> check the box(es) for the script(s) and reference(s) you want to include
3. Click the 'Export' button
4. Enter a unique name for the file in the value for 'File name:'
5. Choose a save location -> click Save
6. Click OK to clear the export location message

By default your exported file will be in the following location:

• (My) Documents/NinjaTrader 8/bin/Custom/ExportNinjaScript/<export_file_name.zip>

Below is a link to the help guide on Exporting NinjaScripts.

However, as you have specifically asked for a screenshot I have provided one.

Thank you for your reply.
It is very helpful that you sent us the screenshots.

When I added the code shown on line 68 of the attached screenshot, I got the error message ""System.DateTime does not have a constructor that allows 5 arguments to be specified".
How can I resolve this?

Also attached is the ninja script file.

Hello ラリー,

The script you have provided is an assembly dll, meaning you have checked the 'Export as assembly' checkbox (which is not in the instructions in post #16).

The code of a closed source assembly cannot be viewed or opened in the NinjaScript Editor, but the script can be run.

What is the specific line of code causing the error?


In the example I have provided you a hard coded new DateTime object is created. However, your logic would be setting the date and time to whatever you wanted to calculate, such as " one hour (8:00) before the market starts the next day after the Tokyo Stock Market closes that day"

If you are needing to know the session start time this can be found with a sessionIterator.

Thank you for your reply.
We apologize for any inadequacies.

What is the specific line of code causing the error?

The error is on line 71.
Also attached are screenshots and the ZiP file again.

Thank you.
The link you sent me has several more links, including the start of a performance session and the end of a performance session, but which one is appropriate for the question I have asked you this time?

[NinjaTrader_ChelseaB]

Hello ラリー,

Currently, I was only demonstrating how a variable works. The actual date time value you assign is up to you.
For this the links on the sessionIterator is not related.

That said, I left some mistakes in the screenshot.


Should you want to retrieve a time in historical data, and not just in real-time, this actually would need to be in OnBarUpdate() where historical data is processed.

Should you want to calculate a custom time, added or subtracted from the session start time, a sessionIterator would be necessary.

Thank you for your reply.

I have tried to add the ZiP file you sent me to the market analyzer, but nothing seems to be displayed.

I also tried to add it to the chart, but the
Net change display is there, but I could not find MyNetChange and could not add it.

Does this mean that I need some additional code in NinjaScript?

[NinjaTrader_ChelseaB]

Hello ラリー,

The column needs to add at least 3 days of data to ensure that the price at 090000 is found.

Set 'Load data based on' to Days, and set Days back to 3 or higher.

Below is a link to a video of testing the script.

Keep in mind this is for educational purposes only as I our policy does not allow me to write code for you. You will need to code the script to your needs.

[ラリー]

Thank you for your reply.

I have watched your video.
When I imported MyNetChange_Modified in my environment, it imported successfully and I was able to add it to the market analyzer.
However, the values are not displayed.
Why is this?

[NinjaTrader_Jim]

Hello ラリー,

Please be sure you have:

• The correct CalculationMode selected,
• That there are several days of data loaded,
• That you are currently seeing realtime data on that symbol,
• That you have historical bar data for that symbol (Can you open a chart?)
• Also make sure that the Data Series used is set to a time frame that will update myLastClosePrice

If you are still stuck, could you share screenshot if the MAColumn settings, as well as a chart showing you have the historical bar data?

[ラリー]

Thank you for your reply.

As you can see in the attached image, the number of days the data was loaded and also
It seems to be able to open the chart.
I also added the AUDUSD symbol and it seems to be displaying the values.
However, the Japanese market was closed yesterday for a holiday.
Is there any influence from that?

[NinjaTrader_ChelseaB]

Hello ラリー,

The script I provided was just an example, which pulls the price at the time of 9 am.

Having enough data would have an influence.

Use prints to debug and understand the issue.

Is there a value printing at 090000?

[ラリー]

Thank you for your reply.

I have added the print to NinjaScript and run it, but nothing is showing up in NinjaScript Output.
Is the print I added to my NinjaScript correct?

[NinjaTrader_ChelseaB]

Hello ラリー,

No, you would want to print in OnBarUpdate() below where myLastClosePrice is being assigned a value.

[ラリー]

Thank you for your reply.

I changed it to Print(myLastClosePrice); instead and ran it, but print (NinjaScript OutPut) nothing is showing up, am I wrong?

[NinjaTrader_ChelseaB]

Hello ラリー,

Because that part of the switch is not evaluating as true.

Why is this code in the switch? I have advised you in post Indicator Development to print this value after it set in OnBarUpdate().
