Reload NinjaScript from within a script

[jculp]

Is there any way in NinjaScript to perform the same action as the F5 hotkey - Reload NinjaScript?
Without using the

SendKeys.SendWait("{F5}") approach?

I am looking for a more automated way to work-around the disconnect between a global line from a time-based chart with an end-of-session anchor point, and the way a tick chart implements the display of that line: the tick chart fails to update the anchor point correctly after initial plot.

The SendKeys approach is undesirable because it requires focus to shift to the time-based chart hosting the script that draws the global lines. If I have to shift focus to the time chart, I may as well continue to do so manually and press F5 manually, which is what I do currently to keep the lines in sync.

I would have liked for NT to keep the end-points in sync as part of the base functionality of global lines, but that is not what happens.

Hello jculp,

Thanks for your post.

No, there are no supported NinjaScript-specific methods or properties to reload Ninjascripts programmatically. You would have to use the SendKeys approach as you have noted.

We are tracking interest in the ability to programmatically reload NinjaScripts in an existing internal feature request ticket and I have added your vote. This request is being tracked under the number SFT-1579.

As with all feature requests, interest is tracked before implementation is considered, so we cannot offer an ETA or promise of fulfillment. If implemented, it will be noted on the Release Notes page of the Help Guide.

Further, here is a demonstration video showing that when a global line is drawn on a 1-minute chart, that line is also drawn on a 1000-tick chart with the same start/end values as the 1-minute chart: https://brandonh-ninjatrader.tinytak...Nl8yMjIzMzc1MA

Thanks for the info. I know that a global line will initially plot correctly on a tick chart. I am looking for the best way to keep the tick chart plot updated when I am using a line whose end-point anchor is end-of-session. I am plotting a single value for the duration of the session: both anchor points have the same y-value. I may switch over to a global ray, although that comes with an additional challenge for what I am doing.

Hello jculp,

Thanks for your notes.

Please share a screenshot showing the behavior you are reporting and what you are trying to accomplish so I may accurately assist.

• To send a screenshot with Windows 10 or newer I would recommend using the Windows Snipping Tool.
  • Click here for instructions
• Alternatively to send a screenshot press Alt + PRINT SCREEN to take a screenshot of the selected window. Then go to Start--> Accessories--> Paint, and press CTRL + V to paste the image. Lastly, save it as a jpeg file and send the file as an attachment.
  • Click here for detailed instruction

Also, send a reduced exported copy of a test script that reproduces the reported behavior so that I may test the script on my end. Note that a reduced copy refers to a copy of the script that contains the minimum amount of code needed to reproduce the issue. All other code is commented out or removed.

To create a copy of your script to modify, open a New > NinjaScript Editor, select your script, right-click in the Editor, select 'Save as', name the script, and click OK.

To export the script, go to Tools > Export > NinjaScript AddOn and ensure the 'Export as compiled assembly' checkbox is unchecked.

The disconnect between end-of-session anchor point and tick chart treatment of it, is a feature of NT lines, not a feature of a script. You can observe the same behavior by drawing a manual line on a time-based chart. Set the end anchor point to 4pm CDT today and make it global. Open a tick chart say, 500 ticks and observe the line. It will initially plot at the tick time scale equivalent to 4pm, but the end line often remains fixed at that same x-coordinate even when the tick time scale has changed or moved past it. See this thread for more detail: https://forum.ninjatrader.com/forum/...on-tick-charts

I am using a script to draw the lines because I use multiple lines, and reloading the script updates all the tick-chart lines. I would like to find a way to auto-reload the script.

Thanks for your notes.

Unfortunately, there are no supported NinjaScript methods or properties to auto reload Ninjascripts programmatically.

We are tracking interest for adding this feature and you vote has been added to the feature request as noted in post # 2.

When/if implemented, it will be noted on the Release Notes page of the Help Guide.
