RE: [amibroker] Bar index of last visible bar

["William Peters" <williampeters@xxxxxxxxxxxx>]

Gordon,
 
This code plots the highest visible barindex. This is a zero 
based array so the last bar will be 1 less than the total number of 
quotes.
 
BV = <FONT 
color=#0000ff>Status(<FONT 
color=#ff00ff>"barvisible"<FONT 
size=2>); HVBIndex = <FONT 
color=#0000ff>LastValue( <FONT 
color=#0000ff>Highest( <FONT 
color=#0000ff>ValueWhen(BV,<FONT 
color=#0000ff>BarIndex()) 
), True<FONT 
face="Courier New">  ); 
Plot(HVBIndex 
,"HVBIndex",<FONT 
color=#ff00ff>1,<FONT 
color=#000000>styleLine);

[amibroker] Bar index of last visible barI'm writing an indicator. 
Searching the newsgroup archives, I found(posted 3/2/2003) what I thought 
was my answer to determining the barindex of the last visible 
bar:"Tomasz posted this to the member section a while 
ago......barvisible = Status("barvisible");r = RSI( 14 );maxr = 
LastValue( Highest( IIf( barvisible, r, 0 ) ) );"So it would seem 
that:aVisBars = Status("barvisible");nLastVisBar = 
LastValue(Highest(IIf(aVisBars, BarIndex(), 0)));should work, where 
nLastVisBar holds the barindex of the last visiblebar. However, nLastVisBar 
always has a value of 0 when I access it incode. Also, the help says that 
Highest returns a NUMBER, but it seemsto be an ARRAY. Without the use of the 
LastValue() function, I can'tuse nLastVisBar in an IF statement.That 
way I initialize nLastVisBar, btw, is at the top of anindicator. The value 
is then used to control a for loop.If anyone can see the error I must be 
missing, I would appreciate 
it.Gordon------------------------ Yahoo! Groups Sponsor
