MultiCharts: Trading Software for Automated Trading and Backtesting

I wonder what function to use when to call for another security into a script.
In Metastock the funktion is, Security("Symbol", Data Array) , is there any funktion in EasyLanguage who is corresponding?

Thanks

From what I understand, you must place the security you wish to call as a data series on your chart, and then call it using the "data2" or "data3" qualifiers - like "Close of data2" where data2 is the second market you wish to follow. To the best of my knowledge, it is not possible to call data on a security that is not already placed on the chart.
