what is Input - Input[0]

[afshinmoshrefi]

I'm very new to NT8.

I have seen Input[0] in several NT8 indicators such as SMA and SUM.
I checked the definition in reference :

"Holds an array of ISeries<double> objects holding the main data input. A ISeries<double> object is added to this array when calling the AddDataSeries() method. Its purpose is to provide access to the main input all Bars objects in a multi-instrument or multi-time frame script."

I am confused with this explanation. can you explain what Input[0] refers to in SMA or SUM? What is the equivalent to "Input[0]" in NT7 ?

Hello afshinmoshrefi,

The equivalent of Input in NinjaTrader 7 is input.

The input is the input series for the script.
If you select the High as the Input series for a script, the Input[0] will return the most recent high for the bar.
If you select another indicator as the Input series for a script, the Input[0] will return the most recent value of that indicator, calculated with input series for that script.
