[amibroker] AmiBroker under attack :-)

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Hello,

One of AmiBroker users brought this to my attention:

http://forum.tssupport.com/viewtopic.php?t=6058

Rarely I see so much nonsense posted about AmiBroker.

Below is the AFL that does what MC people were thinking is "impossible" in AB:


SetPositionSize( 10000, spsValue ); // dollar value of each position 

Buy = True; // just open long trade at very first bar of test 
Sell = Short = Cover = False; // the rest done in custom backtester code. 

SetOption("MaxOpenPositions", 2 ); 

SetOption("UseCustomBacktestProc", True ); 

if( Status("action") == actionPortfolio ) 
{ 
  bo = GetBacktesterObject(); 

  bo.PreProcess(); // Initialize backtester 

  for(bar=0; bar < BarCount; bar++) 
  { 
   bo.ProcessTradeSignals( bar ); 
   
   totalprofit = 0; 
   for( pos = bo.GetFirstOpenPos(); pos; pos = bo.GetNextOpenPos() ) 
   { 
    totalprofit += pos.GetProfit(); 
   } 

   if( totalprofit > 2000 ) 
   { 
      for( pos = bo.GetFirstOpenPos(); pos;  ) 
         { 
          price = pos.GetPrice( bar + 1, "O" ); 
          symb = pos.Symbol; 

         pos = bo.GetNextOpenPos(); 
          
         bo.ExitTrade( bar + 1, symb, price ); // exit long 
          bo.EnterTrade( bar + 1, symb, False, price, 10000 ); // enter short 
       } 
   } 
  } 
  bo.PostProcess(); // Finalize backtester 
}
