Multi Time Frame/Multi Instrument?

[GreenTrade]

I am new to NT from TS w/ some programming experience. I would like to know how to set up a multiple time frame strategies with multiple instruments. i.e. 60 min and 30 min bars with multiple stocks. I have seen examples of each done seperately but not together and wonder how to differentiate between BarArray[1] time and BarsArray[1] stock? Thanks.

The following Help Guide reference should put you in the right direction.

Sorry, I should have read that more closely. So it does not differentiate between time series' or instruments. BarsArray[1] , BarsArray[2] . . . and so on just depend on which order the data series or instruments are added during initialization? Do I have to manually add new instruments if I later decide to apply the strategy to more symbols?

Correct, its based on the order in which the Add() method is called. If at a later time you wanted to add different symbols to the strategy you would have to programatically add them.
