Last Bar on Chart OnBarUpdate not firing

[habibalex]

I have a 2 minute chart for ES futures with CME US INDEX FUTURES RTH session selected. The RTH close is at 1:15 PM PST. I see this OnBarUpdate fire for every day end except the last bar on the chart. Today is 10/25/2020, the last RTH bar is on 10/23/2020 and I only see an OBU 10/23/2020 1:14:00 PM, but not for 10/23/2020 1:15:00. When I load multiple days I can see that the 1:15:00 PM bar is processed (for example 10/22/2020 1:15:00 PM). Is this a bug?

Hello habibalex,

The last bar on the chart closes when a new bar opens.

Is this Calculate.OnPriceChange or .OnEachTick?

If not, are you waiting until a new bar is created?

[habibalex]

it is set to Calculate.OnBarClose, I guess I misunderstood what onbarclose meant. My problem is that when i am between sessions (ie: Sunday evening) my indicators are not updating RTH values for Friday volume profiles because the last bar on the chart's OBU is not being called. How would I solve this?

Hello habibalex,

You could run the script with Calculate.OnPriceChange so you are not waiting for the bar to close for the values to update.

[habibalex]

The profiles are based on the bar close and only the last bar on the chart is messed up. I might try to include some logic in State == State.Transition to check , although this would mean that OBU probably gets called again for the previous session's last bar when the next RTH session starts?

Hello habibalex,

You can have logic that runs when a bar closes and a new bar opens by checking IsFirstTickOfBar to be true, and then allow everything else to update in real-time.

Yes, the last bar of session closes as a new session opens and opens a new bar.

The State.Transition is when a strategy has finished processing historical data in State.Historical, and is transitioning to State.Realtime and is getting real-time orders and actions ready.

How do I update the last bar on the chart in this variable? using -1 used to work in NT7

dsMSopen = new Series<double>(this, MaximumBarsLookBack.Infinite);

if(State == State.Historical){//once indicator is loaded will not continue to update profiles
if(CurrentBar >= Time.Count - 2){//do for last bars

int i = -1;//ninja doesn't call OBU for last bar, so update it here
try{    
    dsMSopen[i] = Open[i] + priceoffset;
    dsMShigh[i] = High[i] + priceoffset;
    dsMSlow[i] = Low[i] + priceoffset;
    dsMSclose[i] = Close[i] + priceoffset;
    //Values[0][i] = Close[i];
    if(negative && dsMSopen[i] > 0){
        dsMSopen[i] *= -1;
        dsMShigh[i] *= -1;
        dsMSlow[i] *= -1;
        dsMSclose[i] *= -1;
    //Values[0][i] *= -1;
    }
}catch(Exception ex){}
}

Hello habibalex,

When Calculate is OnPriceChange or OnEachTick the currently updating bar will be 0 bars ago. For example Open[0].
