Get bar interval automatically

[redsignal]

In my EFS, I like to get the price for some
symbols besides the one being displayed. And when I switch the chart
to different intervals, e. g, daily to 5 min,
I like the EFS be able to figure out the
bar interval being used for these symbols
automatically.

I thought the following line would do it:
myPrice = close(0, sym("IBM"), getInterval());

However, I got an error message saying the
second parameter for close() is not valid.

Thanks.

In order to use the getInterval() method the variable needs to be a series and not a value as in the case of your example ie
var myPrice = close(sym("symbol, interval"));
Once you have the series you can then use the .getInterval() method to retrieve the interval ie
myPrice.getInterval();
For the description and syntax of the series object see this article in the EFS KnowledgeBase
