BARSTATE_NEWBAR Clarification Request

[jg]

Hi,

When using a minute based bar chart for stocks, the
getBarState() flag is set to BARSTATE_NEWBAR when a new bar comes in. My question is:

Does the barstate continue to get set to BARSTATE_NEWBAR for every tick in the bar? That seems to be happening to me and I only want the code to execute on the first tick of a bar. If yes can one code around this? Thanks for any help you may be able to provide.
Regards

Hi Alex,

Thank you very much for your clarification. Unfortunately I am more confused now. Your information leads me to understand that the BARSTATE_NEWBAR is set only on the first tick of a bar. So on a 5 min bar chart, the code should only get executed once per bar. This is not what I am observing. I have the code snippet

if(getBarState() == BARSTATE_NEWBAR) {
....
}

and from the performance monitor window I can see that the code above gets executed on every trade in the bar. I set up the code because I initially understood the barstate to be what you stated but that is not the behaviour I am seeing. I am very puzzled.

Regards,
Jane

The efs will be executed on every tick but the code enclosed in the BARSTATE_NEWBAR conditional statement will be executed only on the first tick of every bar. You can easily verify this by running a counter inside that condition

Hi Alex,

Thank you very much for your reply. As usual you are 100% correct. I in fact did the counter approach you suggested and it confirmed what you say. I was just confused by all the calls being made to the portion of code that computes my series values - as seen in the performance monitor window. Once again, very many thanks for your invaluable help.
Regards,
Jane
