NTb7 FirstTickOfBar

[tquinn]

After loading beta7 some of my indicators seemed to quit working. Doing some research I find that FirstTickOfBar is not working as before. I use FirstTickOfBar to reset some variables which initialize the values in OnMarketData().

OnBarUpdate()
{
if ( FirstTickOfBar)
Print(Time[0]);
}

The above code produces a time print each tick. Is this new to beta7, or am I missing something?

- what timeframe is this? 1 minute?
- which instrument?
- CalculateOnBarClose true/false?
- realtime/historical?

Thanks

The Indicator is designed to only work with RealTime data

- what timeframe is this? 1 minute?
I have tried multiple Volume periods(1000,25000,7000), and multiple time periods (1,5,10)
- which instrument?
ES 03-10
- CalculateOnBarClose true/false?
true
- realtime/historical?
realtime

- CalculateOnBarClose true/false?
true

Hmm .. am I missing something? This would make OnBarUpdate only triggers once per bar right? Meaning, I saw an output in every new bar of my test on 1 min ES.

This code works OK in a new indicator. Yet the same structure in a b6 indicator worked fine, in b7 it does not. And no info in the Log. ???

I don't know. I'm still trying to narrow it down.

protected override void OnBarUpdate()
{
if( ! Historical)
{
if(FirstTickOfBar) Print(Time[0]+" ");
}

}

I see. Strange. May be stripping down your B6 indicator to isolate the culprit helps..

I answered wrong earlier. This is set to CalculateOnBarClose=false, not true. The following code in a new indicator is producing a time print each tick. Should it not just be once per bar?

namespace NinjaTrader.Indicator
{
[Description("Enter the description of your new custom indicator here")]
public class QTFTOB : Indicator
{

protected override void Initialize()
{
CalculateOnBarClose = false;
}

protected override void OnBarUpdate()
{
if( ! Historical)
{
if(FirstTickOfBar)
{
Print(Time[0]);
}
}
}

}
}

Looks like a bug. We'll look into. Thanks for reporting.

[tquinn]

Is there a way I can roll back to b6?

Could you please fire me a mail to "dierk AT ninjatrader DOT com"? Thanks

[tquinn]

Done! thanks.

So, is FirstTickOfBar not working correctly for V7B7?

And if so, is there a workaround on this?

If not, I'm dead in the water with my testing, as several of my indicators rely on this feature.

>> So, is FirstTickOfBar not working correctly for V7B7?
Unfortuantely that is the case. I'm not aware of a work around.

KBJ,

Workaround = check CurrentBar # and the first time it changes, have your own bool that switches to false.

Dierk: Thanks for your speedy answer.

Since this is such a core-functionality of the product, can we hope for a rapid, next beta release with this fixed?
