Hi all,

Sorry for the simplicity of my question. I am learning to code, and stuck with the first example I am reading: SMA.

protected override void OnBarUpdate()
{
if (CurrentBar == 0)
Value.Set(Input[0]);
else
{
double last = Value[1] * Math.Min(CurrentBar, Period);

if (CurrentBar >= Period)
Value.Set((last + Input[0] - Input[Period]) / Math.Min(CurrentBar, Period));
else
Value.Set((last + Input[0]) / (Math.Min(CurrentBar, Period) + 1));
}
}

It seems that Value[1] here should represent the median one bar ago, is this correct?

I tested the the "Value[0]" on a chart, but it shows that it is equal to Close[0].

Quite confused with how NinjaScript would process price data .

Value represents the numeric value of the primary (1st plot) of the indicator. By default, this is initialized to the close price of the underlying data series if your indicator does not set the value to something else.
