FirstTickofBar for Volume

[geekodude]

Hello NinjaTrader!

For the life of me I cannot firgure out how to get the first tick of bar for volume chart(s). I've read the tip in the NinjaTrader 8 documentation:

Tip: In NinjaTrader's event driven framework, bar closures are signaled by the tick that opens the next bar. The price of the last tick of a bar can be referenced by checking Close[1] on IsFirstTickOfBar. For volume and tick based bars, Bars.TickCount and Volume[0] can be referenced to see if the number of ticks / volume meet the criteria to build a new bar.

I need help issuing the correct command to get the first tick of Volume Bar. Any help would be appreciated.

Thank you

Hello geekodude,

Rather than using the items from that description you could do the same concept as the BuySellVolume indicator which uses the CurrentBar index to know when a new bar is created. The first tick which is received that creates a new bar will increment the CurrentBar index. A simple condition can be used to check if the index of the CurrentBar is greater than a stored variable. The script would need to be run OnEachTick in realtime.

private int activeBar = 0;
protected override void OnBarUpdate()
{​
   if (CurrentBar != activeBar)
   {
      //your first tick of bar logic here
      activeBar = CurrentBar;
   }​
}
