Why don't you use just the code provided in the User's Guide?

It's easy to modify profit target to trailing stop working from Low.
Something like that:
Buy = Cross( MACD(), Signal() );
Sell=0;
Lowtrail=0;
for( i = 0; i < BarCount; i++ )
{
if( Lowtrail== 0 && Buy[ i ] )
Lowtrail= Low[ i ];
if( Lowtrail> 0 AND Low[ i ] > Lowtrail )
{
Lowtrail = Low[ i ]; // move trailing level higher if current low is
higher
}
if( Lowtrail > 0 AND Low[ i ] < Lowtrail )
{
Sell[ i ] = 1;
SellPrice[ i ] = Lowtrail;
Lowtrail = 0;
}
else
Sell[ i ] = 0;
}
