newbie needs urgently help with inputs

[Franzl]

hey,
i have a big problem, if i am in the OnBarUpdate() how exactly do i get here my prices? is currentbar the current prize? Can somebody exactly explain what is happening in the code below? I know its a simple moving average and see that also roughly but i dont know what the value-array is and the input array (what is in these arrays?)

 protected override void OnBarUpdate()
        {
            // Use this method for calculating your indicator values. Assign a value to each
            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));
            }

Would be really nice if u could help me with this.

Franzl, Value references the first, main indicator value series - http://www.ninjatrader-support.com/H...AndValues.html

Of course an indicator be hold multiple ones, those would stored in the Values array - http://www.ninjatrader-support.com/H...V6/Values.html

Input references the data source the indicator uses, you can enable this to be user configurable if setting PriceTypeSupported = true in the Initialize() -

hey, thanks for your fast reply, i tried now by myself with creating a new indicator and got this piece of code

 protected override void OnBarUpdate()
        {
            // Calculate the volume average
            double smavol = SMA(VOL(), Period)[0];
            //smavol = 0.9*smavol + Vol[0]*0.1;
            
            // Set the calculated value to the plot
            Plot0.Set(smavol);

it's actually working out, but if i increase the value behind period by 1 to get one bar ago then i dont get a graph if i try to apply that on chart, but actually it should only shift the average back by one or not?
And my next line the Vol[0] should give me the volume of my current bar or not?
