datenum() returns an array so you have to use
lastvalue or selectedvalue of currentdate (e.g., dateyearago =
lastvalue(currentdate) - 10000).

Subject: [amibroker] BarsSince function returning
"Empty"

Hi,

DateNum ();

CurrentTime = TimeNum();

dateYearAgo AND TimeNum() ==

> VolumeYearAgo = Ref
(V,-numBars);

dateYearAgo AND TimeNum() ==
> CurrentTime, V, 1);

However, numBars is always empty and when I use the ValueWhen

it also returns "Empty".

help!
