real-time external value as indicator

[MaxMnn]

Suppose I've got an external program returning something I want to use as a real-time indicator. Black-box if you want. Let it be sun or moon positions on the sky or the frequency of certain words in social media.

What are feasible ways to make an indicator out of this, without having to re-code it in ninja? One way I can think of is creating a pseudo-symbol and feeding it via NtDirect.dll by calling Bid() in external program whenever the value changes. Are there more "natural" ways? Can an indicator listen on a socket or TCP port?

Hello MaxMnn,

Thank you for your post.

As NinjaScript is C# based, most libraries can be used in order to perform various tasks. You have detailed a few ideas in your note. I would leave this open to any one else who would like to comment.
