Address the most righ in historical data

[savekad]

Is it possible to write a condition that will execute a code only when reaching the last bar, when all data is historical?

The goal is to avoid unnecessary evaluations when OBU starts iterating from the first bar and have it evaluating only when reaching the last bar.

It's like the if (Historical) return; thing, but when working with historical I need a different attribute that distinguishes the last bar.

savekad, yes you could work with CurrentBar and Count in combination with the Historical property to determine this. I would start with testing something like -

if (Count -1 == CurrentBar && Historical)

Nice.

Is it possible that Count will return something other than CurrentBar + 1 ?

Didn't fully understand the inflight ticks thing from the article.

[NinjaTrader_Bertrand]

NinjaTrader is an event based and multithreaded architecture, so while the OnBarUpdate() CurrentBar is processed, inflight ticks coming into the system could be seen - for example on shortterm tick based charts and a high volume event occurring.

But I assume that as OBU has started its execution, the Count value won't change in the middle of the process, right?

In other words, as far as OBU cares, Count will always be CurrentBar + 1 when OBU starts evaluating the last bar, even if rapid data arrived before the evaluation completed. Correct?

You are correct in understand, provided CalculateOnBarClose is 'true'.
