Compiling error - "Cannot simplicity convert type..."

[GARZONJ]

I have two user input properties: _smooth to smoothen moving average and MovingAverageTypeLOV enum as the different moving average types a user can select.

I want to add logic that if _smooth = 1, then there will NO smoothing regardless of the moving average type the user selects and _avg = Input. Input comes from the Indicator's Input Series - Price Type parameter.

This is the code that I have in State == State.DataLoaded

else if (State == State.DataLoaded)

            {


                //Initialize class level variable including custom Series<>

                _trend = new Series<bool>(this);

                _avg = new Series<double>(this);



                if(_smooth == 1)

                {

                    _avg = Input;

                }

                else

                {

                    switch (_maType)

                    {

                        case MovingAverageTypeLOV.SMA:

                            _avg = SMA(Input, _smooth).Value;

                            break;

    //                        case MovingAverageType.SMMA:                // Not available at time of Beta 5

    //                            _avg = SMMA(Input, _smooth).Value;

    //                            break;

                        case MovingAverageTypeLOV.TMA:

                            _avg = TMA(Input, _smooth).Value;

                            break;

                        case MovingAverageTypeLOV.WMA:

                            _avg = WMA(Input, _smooth).Value;

                            break;

                        case MovingAverageTypeLOV.VWMA:

                            _avg = VWMA(Input, _smooth).Value;

                            break;

                        case MovingAverageTypeLOV.TEMA:

                            _avg = TEMA(Input, _smooth).Value;

                            break;

                        case MovingAverageTypeLOV.HMA:

                            _avg = HMA(Input, _smooth).Value;

                            break;

                        case MovingAverageTypeLOV.VMA:

                            _avg = VMA(Input, _smooth, _smooth).Value;

                            break;

                        default:

                            _avg = EMA(Input, _smooth).Value;

                            break;

                    }

                }

The error that I am getting is "Cannot simplicity convert type 'NinjaTrader.ninjaScript.ISeries<double>' to 'NinjaTrader.ninjaScript.Series<double>'. An explicit conversion exists (are you missing a cast?)".

I know that this error is do to this line:

_avg = Input;

It is got to be something simple that I am not seeing. Please help.

Thanks.

Hello [email protected],

Thanks for your post.

The error would be expected due to the separate type objects.

You would want to assign in OnBarUpdate() with

if (smooth == 1)
{
_avg[0] = Input[0];
}

You can keep your other assignments in State.DataLoaded, just change the conditional to account for smooth > 1

Note: A new series will be limited to a look back a maximum of 256 from the current bar. If you need a larger lookback you can define the series with MaximumBarsLookBack.Infinite.
