How I can figure out Chart start a new bar

[vlad2017]

I setup NinjaScript.Calculation property to onEachTick or onPriceChange.
so inside the method OnBarUpdate() how I could know when a new bar started?
Thanks.

Hello,

You could know when the First tick of a new bar occurs using IsFirstTickOfBar. This denotes a new bar has started/the prior bar has closed.

I look forward to being of further assistance.

another question

Hi Jesse,
Sorry, somehow i miss this property in help guides. i just started study ninja8 a month ago.

So as i understand if "IsFirstTickOfBar"==true we got the first tick of the bar.
Is any possibility to miss this first tick i mean in case my computer was busy at this moment doing something like putting an order or processing another chart?

does the ninja8 create a fifo stack of chart ticks being waiting to process and i never miss
the first tick?

Thanks,\
Vlad

Hello Vlad,

Yes, if the processor is busy any incoming ticks will be queued and will still be processed.

If you are disconnected, these ticks would not be received and would not be queued.
