How to update the data series of an indicator

[7robert]

Hello, the best way is to explain by an example.

I have a strategy that uses an SMA as an indicator, taking the VX 11-19 data series.
I update the data series to VX 12-19, however the indicator still uses the original VX 11-19 data series. so the results would be wrong...

How can I update the indicator data series to VX 12-19 inside the code?

Thanks!

Hello 7robert,

Thanks for your post.

Please update the AddDataSeries call in OnStateChange under State.Configure to reference the new expiry. Please then recompile your script and after NinjaScripts are recompiled, please remove your strategy and re-add it to ensure State.Configure gets called again to add the new data series.

        private SMA SMA1;
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description                                    = @"Enter the description for your new custom Strategy here.";
                Name                                        = "MyCustomStrategy12";
            }
            else if (State == State.Configure)
            {
                AddDataSeries("VX 12-19");
            }
            else if (State == State.DataLoaded)
            {
                SMA1 = SMA(Closes[1], 20);
            }
        }
