CurrentBid of multiple instruments?

[FireFly]

Can I access the CurrentBid of multiple instruments within a strategy?

I see that I can access the CurrentBid with "Bars.CurrentBid", but can I do that for multiple instruments within a strategy, like I can access the close, high, low etc of multimple instruments?

>>> but can I do that for multiple instruments within a strategy
BarsArray[<seriesNumber>].CurrentBid

>>> close, high, low etc of multimple instruments
Closes[[<seriesNumber>][<barsAgo>]

Multiple instruments can only be used in a strategy, not in an indicator.
Correct?

That is correct
