SampleMultiInstrument

[fle__]

Hi,
I try to develop a multi instrument strategy (an indicator, in fact) but I am having the following problem that I don't understand :

I modified SampleMultiInstrument strategy by doing the following :

            if (BarsInProgress != 0)
                return;
            tmp = ADX(BarsArray[1], 14)[0];
            // Checks if the 14 period ADX on both instruments are trending (above a value of 30)
            if (ADX(14)[0] > 30 && ADX(BarsArray[1], 14)[0] > 30)

As you can see, I just added the tmp variable (defined as private double).

This result in the "Error on calling 'OnBarUpdate' method fro strategy 'SampleMultiInstrument': ADX[barsAgo] out of valid range 0 through -1 was 0"

PS1: I did other modifications : the contract is now "ES 06-09" with PeriodType.Second=30, and I renamed the indicator as the original is read only.
PS2: If I comment the "tmp = ADX(BarsArray[1], 14)[0];" line, then I don't get the error

Thank you for your help.

Please try adding the timeframes in ascending order, i.e. if you want to add a 30 second timeframes as second bars object, then let the primay be a smaller one i.e. 15 seconds.

Thanks for the quick reply.
I will try it now.

For the record, both timeframe were equal at 30 sec.

I've done the test, using 15sec for the primary data and 30 sec for the second.

It does not change anything.

Do you have another suggestion ?

Thanks.

I tried reproducing this, too and it worked as expected on my end - can you please send me the exact code and setup you used to support at ninjatrader dot com Attn Bertrand, then I can take a look and review. Thanks!
