NT8 - Horizontal line label with sound alert function

January 23rd, 2018, 01:30 PM

Hi all,

I recently switched to NT8 and I've been trying to mess with the code of an indicator I found to label the value on the horizontal line drawing tool (F6). The indicator works perfect, however I'm trying to add a function when price crosses that horizontal line that it plays a sound file (.wav file from my NT8 folder).

I've attached the NT8 version as zip and the NT7 version as the .cs file which I was using and worked well.

Here is the NT8 code and any suggestion would be highly appreciated, thanks in advance:

I'm not a coder

Perhaps you can just use these two (ported from NT7 to NT8) and add both to your chart.
of course it may be you've tried this already. :-)

Hello.
The indicator works. It indicates the price level but does not play sound. This is not yet implemented.

September 30th, 2020, 03:28 PM

The documentation has an example of how to do this. Of note, indicators handle the call to PlaySound method a bit differently so watch out for that. Here is the link.

Essentially, you define your logic, such as with if statements, then if your criteria is met, put your call to PlaySound in that conditional logic block.

Remember, it won't work during a backtest or when you're loading data. (State.Historical)
