New and Fun error code

[bobby1001]

// plot below by replacing 'Close[0]' with your own formula.
myDataSeries.Set(((High[0] - Low[0])/2) + Low[0]);
myDataSeries1.Set((High[0] - Low[0]) + High[0]);
myDataSeries2.Set(Low[0] - (High[0] - Low[0]));
Plot0.Set(SMA(myDataSeries[0], myInput0));
Plot1.Set(Close[0]);
Plot2.Set(Close[0]);

What is the problem with this? This is the error code I'm getting.
The best overloaded method match for 'NinjaTrader.Indicator.SMA(NinjaTrader.Data.IDataS eries, Int) has some invalid arguments, specifically Argument 1 cannot covert form Double to IDataseries. What is double? What does that mean? How is it used? The online manual is, at best, vague.

Hi bobby1001,

This line Plot0.Set(SMA(myDataSeries[0], myInput0));should be Plot0.Set(SMA(myDataSeries, myInput0)[0]);A double is basically a number with decimal points. The first parameter when you call SMA() is suppose to be a DataSeries object not a double object. To get the DataSeries object you can remove the [0] indexing. In this case, you will also need to add an index reference at the end of SMA(). Make sure myInput0 is an int and it should compile after that.

It worked fine. I think I understand why, but wanted to check to make sure. The [0] we added refers to the SMA for the plot, correct?

Thanks again.

Correct. It refers the latest SMA() value to the plot.
