How do I change historical data in a series?

October 27th, 2021, 06:57 AM

Hi all!
I am writing an indicator in MultiCharts and ran into such a problem.
I declare the series "private VariableSeries <Double> v1;".
I write the data "v1.Value = 100;"
I want to change the history data "v1 [10] = 50;"
The program swears. He says that you can only read.

If on the current bar you say v1=50 then 10 bars from now, if you reference v1[10] it will equal 50.

The history is created as each bar passes, and you cannot go back and change that.

Or maybe I misunderstood your question.

Rusti,

you could for example use a List instead of VariableSeries. This would allow you to change values at an index.

Thanks for the tip.
Can't find List. Can you tell us in more detail? What is this variable? What is her name in the MCH? And then I myself.
Thanks in advance!!!
