DataSeries in a strategy

[binwang2]

Hello, NT experts,
User manual says all indicator methods accept DataSeries objects as arguments.
Will DataSeries (like myDataSeries.Set(High[0] - Low[0]) created in a strategy work perperly?

Hello Binwang,

Yes, you should be able to pass this DataSeries into indicators that are looking for a dataseries input. While it should compile, it won't always make sense to use this for all indicators. Let us know if you're having difficulty with any particular implementation.

If i want to use multiple dataseries in a multiple instrument strategy, each dataseries matching one isntrument, should the initlization be all the same like this:
myDataSeries1 = new Dataseries(this);
myDataSeries2 = new Dataseries(this);
...
Or each one has to be specific to its corresponding instrument?

This will work, but you will also need to use Add statements for each instrument in the series.

You'll then have to be sure you're referencing the correct bar object when setting your DataSeries.

I found i can only add up to 6 instruments into a strategy.

If i put more then 6, the strategy will compile but data beyond 6th instrument won't load.

Should that be the case?

Hi Binwang,

No, you should be able to add more than 6 instruments to a strategy. Are you getting any error messages in the log tab of the control center?

[binwang2]

No, there is no error message.

I re-started NT and now the strategy loaded more than 6 instruments.

Please consider issue resolved. Thanks for yout attention.
