Trendline LE Alert

I am trying to modify the default Trendline LE signal to become an alert when the price crosses above the manually drawn Trendline se code below. Although it compiles I get a message "Error in study Trying access at data to future. Bars reference valu: -1" ...Please help. Thanks

I am trying to modify the default Trendline LE signal to become an alert when the price crosses above the manually drawn Trendline se code below. Although it compiles I get a message "Error in study Trying access at data to future. Bars reference valu: -1" ...Please help. Thanks

Code: Select all

[IntrabarOrderGeneration = false]
inputs:
TLRef( 1 ) ;


variables:
var0( TL_GetBeginDate( TLRef ) ),
var1( TL_GetBeginTime( TLRef ) ),
var2( false ) ;

var2 = ( Date = var0 and ( BarType = 2 or ( BarType = 1 and Time >= var1 ) ) )
or Date > var0 ;

condition1 = var2 and High < TL_GetValue( TLRef, Date, Time ) ;
if condition1 and close crosses over TL_GetValue( TLRef, Date next bar, Time next bar ) then
Alert ;

is it possible to

close crosses over Date next bar, Time next bar?

is it possible to

close crosses over Date next bar, Time next bar?

I believe it needs to be according to the reserved word if I'm not mistaken....

TL_GetValue( TLRef, Date, Time )
