Cannot apply indexing with [] to an expression of type "double"

[bltdavid]

You cannot index a double, since this makes no sense.

You can index a Series<double>, which is a big difference.

A double and a Series<double> are not the same thing.

How is Hist defined?
From the code, it looks like it better be a Series<double>.
Is it?

How is Histog defined?
Ok, I see this one, it is a double.

How is priorHistog defined?
From the code, it looks like you're using it as a double
but then you also use it a Series<double>.
Which is it?

I agree you need help.

But I don't think you've provided enough code for me to
divine an answer -- can you attach your entire script?

It looks like you're confused about the differences between
double variables and Series<double> variables.

What are you trying to do, exactly?

Hello 0x7e2,

Thanks for your notes.

bltdavid has provided some great information on the topic..

You would have to use a Series<double> variable instead of a double variable if you want to be able to access values using an index.

See this help guide page about creating Series<T> variables: https://ninjatrader.com/support/help...t8/seriest.htm
