CalculateOnBarClose

[futurenets]

Am I right that the last closing tick event of a bar is also the first opening tick of the next bar?

So if OnBarUpdate() is triggered on the bar close (if CalculateOnBarClose = True)
should FirstTickofBar be true?

futurenets, you are correct in understanding - in out event based architecture the bars are not considered closed until the open tick of the new bar is seen, so opening tick and closing tick are essentially the same.

ok thanks

but I don't think FirstTickofBar is true when this happens?

so if CalculateOnBarClose = True then the script will be executed on the closing tick of the bar Close[0]

if CalculateOnBarClose = False then the script will be executed on all ticks
and FirstTickOfBar = True on the opening tick of the bar Close[0] (this is the bar after the above)?

It would be, it's the same (closing) tick.

ok thanks.

Just getting a bit confused on which bar Close[0] refers to when FirstTickOfBar = True

e.g. if last tick on last bar of week closes on Friday then the same tick can't open the next bar until Monday?

The bar would not be closed on Friday, it would close as you saw the first tick on Monday (CalculateOnBarClose given true in this example)
