[amibroker] Help: How to determine a future bar is available, i.e. ref(c,5)

["clement" <clement@xxxxxxxxxx>]

Hi,

How to determine a future bar is available? i.e. 4 days from today?

If I use ref(c,5) to get value, it is 0 if is not available. Can I use it to determine whether the bar is available? Or there is a better solution?

I would like to do some calculations if a few future bars are available. Or else, I will stop the calculations. How to determine that?

Thank you in advance.

Clement
