Barstate_newbar

[AssetHound]

Just to clarify . . . for calculations inside a loop using this bar state, do they execute on the first tick of a new bar and that's all? And, what happens when the next new bar is formed?

I'm thinking that all ticks in a bar other than the first one would be ignored. It's not clear to me in reading the KB materials.

Thanks.

Hi AssetHound,

You are correct, this conditional is met on the first tick of a new bar. You must be careful because the last tick before a new bar is the end of that bar. You can have issues with historical data loading and the technical indicator looking different between live conditions and the historical data if you are not careful...

Thanks, Steve. Always good to make sure things are operating as you think they are operating.

Hi Steve,

What would be the best way to prevent the issues with the historical data?

Hi Wayne,

I believe this is covered in the tutorials, I'm not sure about the specific link, but I'm sure you could find it if you would like to pursue the subject area further. Regardless, what I was trying to do was to quickly confirm AssetHound's understanding of the different getBarState() return flags and their relationship with price behavior intra-bar.


When live, BARSTATE_NEWBAR condition is met the first tick of a bar (ONLY once per bar), and close(0) tracks tick price intra-bar and represents the tick price which can change value every tick intra-bar. close(0) is not finalized until the last tick in the bar, at which time it represents the close of the bar (one tick before a BARSTATE_NEWBAR condition). Historical data is fixed and when a BARSTATE_NEWBAR condition is met, close(0) represents the closing price which is the value that corresponded to the last tick of the live data of the bar.

Hope this helps.
