I'm try to translate this formula(Metastock) in Amibroker(AB)
(C>HautP AND C>BasP,5, If(C<BasP,0,PREV))
A guy from AB said to use the loop.
I'm use a formula on site Internet of AB(Percentage Trail Stop)
Why when I'm use my Formula, I'm obtain :
Error 6. Condition in IF, WHILE, FOR statements has to be Numeric or Boolean
type. You can not use array here, please use [] (array subscript operator) to
access array elements
And when I'm use the formula Percentage Trail Stop,
I don't obtain ERROR 6 ?????????????
WHY ???????
Thank

Percentage Trail Stop
My Formula
StopLevel =Param("Percentage Trail Stop",0.05, 0.01, 0.6, 0.01 );
LK=50;
FF=10;
A1= IIf( L> Ref(HHV( Close,LK),-5), 1, 0);
A2= Sum( A1, LK ) ;
A3= IIf(C>0, FF, 0);
Buy = Cross(A2,A3);
Sell = 0;
trailARRAY = Null;
trailstop = 0;
for( i = 1; i < BarCount; i++ )
{
if( trailstop == 0 AND Buy[ i ] )
{
trailstop = High[ i ] * (1-stoplevel);
}
else Buy[ i ] = 0; // remove excess buy signals
if( trailstop > 0 )
{
trailstop = Max( High[ i ] * (1-stoplevel), trailstop );
trailARRAY[ i ] = trailstop;
}
if( trailstop > 0 AND Low[ i ] < trailstop )
{
Sell[ i ] = 1;
SellPrice[ i ] = trailstop;
trailstop=0;
}
}
PlotShapes(Buy*shapeUpArrow,colorBlue,0,Low);
PlotShapes(Sell*shapeDownArrow,colorRed,0,High);
Plot( Close,"Price",colorBlack,styleBar);
Plot( trailARRAY,"trailing stop level", colorRed );
_SECTION_BEGIN("Cr.HautP.");
TimeFrameSet( inDaily ); // switch now to Daily
HautP= Ref(H,-1) ;
BasP= Ref(L,-1) ;
TimeFrameRestore(); // restore time frame to original
StopLevel = BasP ;
Buy = Cross(C,HautP) ;
Sell = 0 ;
trailARRAY = Null;
trailstop = 0;
for( i = 1; i < BarCount; i++ )
{
if( trailstop == 0 AND Buy[ i ] )
{
trailstop = HautP ;
}
else Buy[ i ] = 0; // remove excess buy signals
if( trailstop > 0 )
{
trailstop = Max( HautP, trailstop );
trailARRAY[ i ] = trailstop;
}
if( trailstop > 0 AND Low[ i ] < trailstop )
{
Sell[ i ] = 1;
SellPrice[ i ] = trailstop;
trailstop=0;
}
}
PlotShapes(Buy*shapeUpArrow,colorBlue,0,Low);
