Re: [amibroker] Re: Reference first signal

["Tomasz Janeczko" <amibroker@xxxxxx>]

Hello,

You should simply use max loss stop.

Buy = Cross(C,bbandtop(c,20,2));
sell= 0;

ApplyStop(stoptypeprofit,stopmodepercent,5,true);
ApplyStop(stoptypeloss, stopmodepoint, BuyPrice - L, true ); // stop is at the level of LOW price of buy bar

If you don't want to use ApplyStop (for some strange reason :-)) you can loop
to implement your own stops directly in the code as shown in the bottom of
http://www.amibroker.com/guide/whatsnew.html

/* 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;
}
