Help Guide says Don't do it

[JerryWar]

I would like to Add() two DataSeries to an indicator/Strategy. But I want to do it as a multiple
of the compression of the Primary Data series. Example if the primary was 1 min I want the code to add in multiples of 7 times that or a 7 min and 49 min. The issue I see is that in Initialize where the add()'s would be, according to the help guide you are not supposed to access BarsPeriods[0].Value. which is the only way I see to get the primary data value the chart was created with.

Does anyone know how this might be accomplished?
Thanks

Hello JerryWar,

Thanks for your post.

That is correct. It is not supported to add data series like this on the fly. I'm am not aware of a work around.

You can do this and it may work, but please note that it is not supported to do so.

Also, you would want to use BarsPeriod and not BarsPeriods[0].

For example:

Add(BarsPeriod.Id, BarsPeriod.Value*7);

Thanks especially for the suggestion. Its easy enough to give it a try. My only hesitation was that it might actually work but cause seemingly unrelated issues later on.

Jerry,

Really its not supported because its really easy to get in to trouble when doing things with this.

What you are asking for is fairly straight forward and should work fine and continue to work fine as long as you are only doing this.

Using multiple data series and trying to use BarsPeriods[1] or doing incrementing or trying to use an if statement to decide how many data series to use can cause NinjaTrader to out right crash.

Chelsea,
It does appear to work great. It makes my life much simpler. I will stay away from the conditional statements. I can see where I might have tried it.

Thanks
Jerry
