indicator string output

[voyager]

Hallo to everyone

I have a question.

Is there a way to pass string output(not plot) created by an indicator, to a strategy ?

[NinjaTrader_Bertrand]

voyager, it should be possible as long as the string variable is exposed to be accessed from the strategy (public property).

Thanks Bertrand

You're right

Hallo again

Continuing the above, i have a custom array created by a public class with a public constructor. When i declare the custom array as public, ninjatrader creates serialization error.

What is wrong ?

voyager,

Please be aware that this is beyond the level of support we can offer as this is much more advanced C# concepts.

Please post exact code with the exact error message. Thank you.

Here is a simple and ready to use example.

If this is working with ninjatrader 7 then there is no need to bother more.

As i don't have ninjatrader 7 i would appreciate if anyone could check it out.

Thanks

If you compile with name "JTest"
and insert it on a chart
and then try to save workspace,

it creates an error:
indicator .... could not be serialized. Please refer help ... e.t.c

Unfortunately this is beyond what we provide support for. However, here is a hint: XML serialization is a .NET standard technology which comes with some clear restrictions on your code (please see MS docs). Also: you should be able to find lots of references on this issue on the forum.

Thank you. I'll check it
