Re: [amibroker] Help needed with simple Lowest or LLV afl code

[Graham <kavemanperth@xxxxxxxxx>]

try this to find the lowest close for entire history

Lowest_Close = lastvalue( Lowest(Close) );
L_date =lastvalue(  ValueWhen( Lowestbars(Close)==0, DateTime(), 1) );
Lowest_date = NumToStr( L_date, formatDateTime);
Title = Name() + ": Total bars " + BarCount + " Low = " + Lowest_Close
+ " on " + Lowest_date;
