How can I apply the period to this indicator that I am creating?


protected override void OnBarUpdate()
{
//Value[0] = CurrentBar == 0 ? 0 : Input[0] - Input[Math.Min(CurrentBar, Perido)];

double O = Open[0];
double H = High[0];
double C = Close[0];
double L = Low[0];
double V = Volume[0];
double Buying = V * (C - L) / (H - L);
double Selling = V * (H - C) / (H - L);
double Delt = Buying - Selling;


Value[0] = Delt;

if (Delt > 0) {
PlotBrushes[0][0] = BrushUpEnd;
} else {
PlotBrushes[0][0] = BrushDownBegin;
}

Hello fitmar2525,

The SMA included with NinjaTrader is a great example of using a period.

The public input is declared on lines 84 to 87, the default value for this is set on line 46, and the value used for calculations and barsAgo values in the logic on lines 65 through 79.
