might be a dumb question but im stuck

[duncanhoo]

trying to do a simple MTF indicator.

I understand how to add a new period to the script and have that compiling:
Add (PeriodType.Ticks,Ticks);

I am trying to add a comparison of CCI on that second period to a prior period (ie, if CCI is higher this bar vs. previous bar then do something).

How do i reference say a 14 period CCI on that second period?

I believe CCI(14)[1] refers to the 14 period cci of the second period type i added to the script....but then how to i compare that to a prior bar?

CCI(14)[1][1]?

thanks

Hello,

Thanks for the forum post glad to help.

Multi-time frame works in NinjaTrader is based on whats known as BarsInProgress. The BarsInProgress is the bar that OnBarUpdate() is currently running on. OnBarUpdate() will get called for each Multi Time Frame you add in.

You can access values of each BarsInProgress individually like so:

//Primary Series 1 bar ago
CCI(BarsArray[0], 15)[1];

//Secondary Series 1 bar ago
CCI(BarsArray[1], 15)[1];


However you do not always need to use the BarsArray. As if you use the filter at the start of OnBarUpdate() if (BarsInProgress == 0) { this is primary series and you can use standard indicator call CCI(15)[1];}

Please see this guide for more information.
