Floating tick counter

[oshri17]

Is there any way to fix this indicator to work on NT8?
I keep getting errors and I'm still learning ninjascript.

Thanks in advance

Hello oshri17,

What errors are you seeing when using the script?

[oshri17]

Please see attached picture

Hello oshri17,

It looks like you are missing most of the standard references at the top of the script. Please open the ADL indicator and copy the using statements from that script and replace the using statements you have in your script, then recompile. You may still have additional errors but that would be a starting point toward working through the errors. You generally need all of the standard using statements so it is not suggested to edit the using statements in the region Using declarations.

Thanks for the reply.
after doing that I got a lot more errors, most of them are the same.
please let me know how to fix those

Hello oshri17,

It looks like the code you originally posted is for NT7, you would have to convert each of the items that are having errors to nt8 equivalent code. You can find a lot of these items on the code breaking changes guide: https://ninjatrader.com/support/help...ng_changes.htm

I would suggest to remove this indicator and get back to a compiled state then create a new empty indicator using the NinjaScript editor. From there you can go line by line and copy 1 line at a time into the new script resolving each error as you go. One item to note is NT8 does not use the initialize override, that is replaced with OnStateChange and is listed in the code breaking changes guide. Another note is that Color.Black would be Brushes.Black.

Drawing objects are also different now, it would be best to get the syntax from the help guide for the object in question and re code those parts.

https://ninjatrader.com/support/helpGuides/nt8/draw_text.htm?zoom_highlightsub=draw.text

You can view NT8's built in TickCounter code for a lot of the other concepts that this is using.

Thank you. I got this to work
