Re: [amibroker] Re: Help on Debugging this If-Else Loop

I am not sure you require loops to do what you are looking for.

SlowMA = MA(C,20);

FastMA = MA(C,5);

Buy = FastMA > SlowMA ;

Sell = Cross(SlowMA , FastMA) OR SellPrice > (BuyPrice + 10);

Short = FastMA < SlowMA;

Cover = Cross(FastMA, SlowMA) OR CoverPrice < (ShortPrice - 10);

Instead of AND, I have used OR since both Crossover and Price being above 10 
pips cannot happen simultaneously.

Cheers

  Still toying around with this and still can't get it to work. I just can't 
seem to figure out how to specify the current price.  Thought that the 
ValueWhen function might be able to help.

  All I'm trying to achieve is this very simple test system, for Forex Intraday:


  1.   Buy Long position when the fast MA is above the slow MA
  2.   Sell the Long position when the fast MA falls below the slow MA, AND the 
current price is at least 10 pips higher than the original entry price.

  3.   Enter Short position when fast MA is below the slow MA
  4.   Sell the Short position when the fast MA rises above the slow MA, AND 
the current price is at least 10 pips lower than the original entry price.

  Code below.  Anyone? 




  Buy =  (myMA1 > MyMA2);
  Short = (myMA1 < MyMA2);

  PriceAtBuy = 0; 
  PriceAtShort = 0;


  for( i = 0; i < BarCount; i++ ) 
  { 
       if( PriceAtBuy == 0 AND Buy[ i ] ) 
       {   
         PriceAtBuy = Buy[ i ];
         ValueAtBuy = ValueWhen(Buy[i]>0,C,1);
       }

       if( PriceAtShort == 0 AND Short[ i ] ) 
       {
       PriceAtShort = ShortPrice[ i ];
       ValueAtShort = ValueWhen(Short[i]>0,C,1);
       }
   

       if( 
           (myMA1[i] < MyMA2[i]) AND (PriceAtBuy > 0) AND (C[i] > 
(ValueAtBuy[i] + 0.0010))
         )
       {
         Sell[ i ] = 1; 
         PriceAtBuy = 0; 
        
       }
       else 
         Sell[ i ] = 0; 


       if( 
           (myMA1[i] > MyMA2[i])  AND (PriceAtShort > 0) AND (C[i] < 
(ValueAtShort[i] - 0.0010))
         )
      { 
         Cover[ i ] = 1; 
         PriceAtShort = 0; 
       } 
       else 
         Cover[ i ] = 0; 
      

  }
