["Paul Ho" <paul.tsho@xxxxxxxxx>]

try this

d = dayssince1900();

say event = cross(c, ema(c, 50);

ayearago = valuewhen(event, d - 365);

to translate it to datetime

dt = valuewhen(d == ayearago, datetime());

Subject: [amibroker] How to relate a date to barindex

I am trying to find the date for 252 bar ago. I have written the
following code. However, it does not work! any suggestion is much
appreciated. TIA

SetBarsRequired(10000);
BarIndx = BarIndex();
aYearAgo = BarIndx - 252;

AYearAgoDate = LastValue(ValueWhen ( BarIndx <= aYearAgo ,DateTime()));
_TRACE("AYearAgoDate: " + NumToStr( AYearAgoDate));

Title =
"BarIndex: " + BarIndx
+ " \n" + "aYearAgoBar: " + aYearAgo
+ " \n" + "A Year Ago Date: " + WriteVal( AYearAgoDate , formatDateTime)
+ " \n" + Interval(2) + " - " + Date() ;
