Multi TimeFrame Compile time error

[DaveS]

I'm wanting to use several time frames of the same instrument as input to indicators, but have fallen down at the first hurdle. In the help guide it says that a bars object for the same instrument as BarsArray[0] can be initialised by

protected override void Initialize()
{
Add(PeriodType.Minute, 3);
}

but when I try this I get compile time error CS1501, "No overload for method 'Add' takes 2 arguments"

Presumably a third argument is required, before PeriodType, indicating the instrument to be used? If so, is there an argument that I can use which indicates the BarsArray[0] instrument?

Hi DaveS,

Indicators based on mutiple time frames are not supported in NinjaTrader 6.5.

However in our upcoming NinjaTrader 7 this will be possible.

Hi Bertrand.
When I mailed your people about Multi Time Frame, they referred me to YOUR help Guide -

http://www.ninjatrader-support.com/HelpGuideV6/helpguide.html?MultiTimeFrameInstruments

Which is quite a long document explaining how to do it.
Are there two NinjaTraders? Or what?

Hi DaveS,
there's a big NinjaTrader family and growing steadily ...

This section from our help guide deals with Mutiple Time Frame strategies, not indicators.

OK, I was sent the link in an email and never bothered to trace it to its source, I should have done!
So, maybe I can get around this and still use NinjaTrader:-

1) Can 'Shared Drawing Methods' be used by Strategies AND Indicators?

2) If the answer to 1) is yes, is it OK to use a Strategy that does not submit any orders?

3) Are you able to say when NinjaTrader v7 will be available?

Thanks

Hi DaveS,

Yes, you can draw from within a strategy and you don't have to submit any orders.

We plan to release NinjaTrader 7 in the first quarter of 2009.
