Access data from within my c# code of another indicator

[TraderChris123]

Hallo, assume you have a chart with an vwap and an sma on it, added via the usual way.
Now I want to program my own indicator in c# and have access to the values of vwap and sma for each bar within my oncalculate() method.
How can I access these values of other indicators, viusiosble on the chart, but not initiated in my own code ?

Not initiated in your own code?
Do you know what you're asking?

You mean you want to search through the current indicators
on the chart, identify the vwap and sma, and use the ones
you find on the chart?

You sure you want to do that?
Seems like a big pain to do it that way.

I think you should 'initiate' the indicators you want directly
inside your own code -- this is the normal way to do it.

Yes, that was the plan.

Take a look at this.

Thank you.
The disadvantage of initiating the indicator in my code is, from my point of view, that i have to either configure them hard coded or have to present all setting possibilities to the user from within my code. The other way around I could use the settings that already exists and I would only have to access the values of the indicators.

Maybe so, but your development path seemed
kinda odd to me.

I mean, vwap and sma are not very intensive
when it comes to user parameters.

And what if the vwap and sma are not on the chart?

You're making a lot of extra work for yourself (and
the user) to avoid some relatively trivial things.

Are you going to require the user to add the VWAP
and SMA to the chart before adding your indicator?
That's extra work for the user.

What about if they have 2 or more SMAs on the
chart, how will you know which one to use?

Your current approach will lead to madness.

Just my 2˘.

Thx for yout hint, maby you are right and saved me from lots of trouble ;-)

Hello, thanks for writing in. The only supported way for indicators to read other indicators is through "hosting" the indicator i.e. initializing an indicator object from within the host indicator. For an example of this, see the "SampleMACrossover" strategy.
