How to make reference to a second data series

[Asahi]

Hi,

I'd like to know how to make reference to a second data series. For example, when the trading instrument is SPY , I make reference to the ROC of VIX.
Thanks.

@Asahi Your request is somewhat vague... Are you looking to reference another chart, or just reference trade data from another symbol... If you would take some time to further explain your vision we will be better able to help...

That being said, trade fundamentals like open, close, high, low can be accessed for any symbol by using close(symbol = "SPY"), for example...

Hi rad,
Thanks for your info.
So you mean when I trade SPY, my trading strategy can make reference to the indicator value of other symbol, such as VIX index, by specifying something like this,

if ROC (Symbol = "VIX") > 0.3 ...

Thanks
