how to call indicator from indicator

[cincai]

I know have some function like :
AddChartIndicator called in State == State.DataLoaded

However, this is only work for using strategy to call indicator.

What i want is called indicator from indicator.

Hello cincai,
You can do as below:

1. Before OnStateChange(), private SMA sma1;
2. In DataLoaded, sma1 = SMA(Period);
3. In OnBarUpdate(), now you can use as required. Example - Plot1[0] = sma1[0]; // this will plot SMA

Hope it helps!

Hello cincai,

Thanks for your post.

For indicators, there is not an AddChartIndicator() method. Just to clarify, AddChartIndicator() is a convenience method for the purpose of adding indicators to a chart when a strategy is loaded. The strategy does not have to use the indicator within the strategy (typically they do).

As forum member s.Kinra advised, in order to see a plot from another indicator, in an indicator, you would have to create a plot for it and assign the indicator value to it. You would create a private instance of the indicator, initialize the indicator in state.DataLoaded and in OnBarUpdate() assign the indicator value to the plot you created.
