[amibroker] Re: Modified Trailing stop

[pmxgs]

Hi Howard,

 yes, na example would be nice.
 I've tried to modify this one (included in the users guide), but I'm
having trouble with referencing the entry price.

/* a sample low-level implementation of Profit-target stop in AFL: */

Buy = Cross( MACD(), Signal() );

priceatbuy=0;

for( i = 0; i < BarCount; i++ )
{
     if( priceatbuy == 0 && Buy[ i ] )
     priceatbuy = BuyPrice[ i ];

     if( priceatbuy > 0 && SellPrice[ i ] > 1.1 * priceatbuy )
     {
       Sell[ i ] = 1;
       SellPrice[ i ] = 1.1 * priceatbuy;
       priceatbuy = 0;
     }
     else
       Sell[ i ] = 0;
} 

 thanks
