Read values from third party indicators

[facuevasm]

Hello guys!

I wonder how I should read an external indicator inside my strategy, depending that this indicator is from a third party vendor that I purchased and not the ones that comes with Ninja. ¿Do I need to create a private instance of the indicator, then pass input values to it? Do you have any code example?

Thank you!

Hello facuevasm,

Thanks for your post.

I see that you mention an 'external' indicator.

To clarify, is this an indicator that runs externally (outside) of NinjaTrader?

Or, is this a third-party indicator that was imported into and runs in NinjaTrader?

If this is a third-party indicator that is imported into and runs in NinjaTrader, you could create a private instance of the indicator in your strategy as you have described.

See this help guide page for adding indicators to strategies: https://ninjatrader.com/support/help..._strategie.htm

You could also use the Strategy Builder to create a condition based on an indicator (such as SMA) and click the 'View code' button to see the generated syntax for an example of how indicators are added to strategies.

It really depends on the third-party vendor.

What I mean is ...
The indicator author has the ability to expose (or hide) information
from the strategy author -- which means the strategy author needs
to be aware of what methods and properties the indicator makes
public. Documentation usually comes with third-party indicators,
precisely to describe these kinds of programming details.

Some vendors do a better job of this than others. I've seen the
same indicator sold as a basic version and a more expensive pro
version. The only difference was the pro version exposed the
methods and properties needed by a strategy, where as the
basic version hid these things on purpose. Not all vendors do
this -- I'm just saying the choice is theirs to make. It is intrinsic
to the indicator what is public and what is private, you won't be
able to get around that.

You really need to contact the third-party vendor and ask them
your questions. They should be able to give you examples of
how your strategy can interact with their indicator.

Good luck!
