Multi-timeframe indicator referencing

[LazKz]

Hello,
i am trying to build a multi-time frame strategy processing in real-time with setting
'CalculateOnBarClose = false'

The primary bars are 10min while secondary bars object is Add(PeriodType.Tick, 10);

My question is the following:
If I would like to initiate something on the secondary bars object with condition examined on the primary bars, can I reference the MACD on the primary bar to trigger conditional action on the secondary bar with...

if( MACD(BarsArray[0],8, 21, 10).Diff[0]) > 0 )
{
if(Highs[1][0] > Highs[1][1])
{
EnterLong("","")
}
}

...or the 'if (BarsInProgress == 0)' and 'if (BarsInProgress == 1)' conditions are necessary to reference the correct bars object?

Thank you

Hi LazKz, welcome to the NinjaTrader support forums! Both methods are fine - either use the BarsArray and point to the correct bars object with the index value or call the methods in reference to the BarsInProgress and which bars object is calling the OnBarUpdate().

Thanks Bertrand,

There is one thing I am still not sure of. When checking which bars object is calling the OnBarUpdate() method with the following code

if (BarsInProgress == 1)
{
MACD(8, 21, 10).Diff[0] > 0
}

the MACD().Diff[0] without the BarsArray[1] defining the Inputdata would it refer to the secondary Bars object or to the primary bars object?

When in BIP=1, a regular call would refer to the secondary bar object.
