BARSTATE_NEWBAR vs bar index

[AssetHound]

Right now, I have EOD but am moving to real-time later. I have setPriceStudy(true) and setComputeOnClose(), and realized that for studies using an interval of less than daily, getCurrentBarIndex() never gets to zero. It stops at -1. It does result in zero for daily, weekly and monthly charts. The popup on the price chart, however, does show the first bar to have an index of zero regardless of interval, and high(...) does return a value for the "zero" bar.

With BARSTATE_NEWBAR, I have to check for interval first and then the bar index equal 0 or -1 before executing some code after the chart is initially loaded and after subsequent new bars. Is this correct? Something doesn't seem right.

Thanks.

Hello AssetHound,

The setComputeOnClose() function does not take affect on daily, weekly or monthly intervals. If you are using a formula on both daily and intraday intervals you can check for the daily and higher intervals with isDWM().

You should be able to look at bar index of 0, for example close(0), regardless of the use of setComputeOnClose(). close(0) etc will refer to the current bar that is being processed. When setComputeOnClose() is used the formula does not process bar 0 because bar 0 is not a completed bar until it becomes the new bar -1. Hope this helps.

That explains it and matches what I found out. Thanks for letting me know about isDWM(). That's helpful and I missed it.
