[amibroker] 3 in 1 trading system

[DrazenStricek12]

Hello,

Im building system:
1. that goes long only ie. buys  down bar in uptrend
2. that goes short only ie. shorts up bar in downtrend
3. goes  long and short when both trends are present   

The problem is that it signals error because IF  loop has to be numeric and not 
aray.
Could anyone point me to where I can find solution  for this problem ?



It goes like this

// CODE BEGINN ********** 3 in 1 EOD system

p=20;

uptrend=RSI(p) >55;
dwtrend=RSI(p) < 45;
DIR=IIf( uptrend,5 ,IIf( dwtrend,4 ,7)); // direction up down both

u1=C >O;// trigger
d1=C < O;

 
if( dir==5)
{
 // LONGS
Buy=d1* dir==5;
Sell=u1*dir==5;
Short=0;
Cover=0;
}

 if( dir==4)
 {
 // SHORTS
 Buy=0;
 Sell=0;
 Short=u1*dir==4;
 Cover=d1*dir==4;
 }
  if( dir==7)
  {
  // BOTH
  Buy=d1* dir==7;
  Sell=u1*dir==7;
  Short=u1*dir==7;
  Cover=d1*dir==7;
   } else;

// 
//  *****************END CODE


I tried this combination but  it is not working:


p=20;

uptrend=RSI(p) >55;
dwtrend=RSI(p) < 45;
DIR=IIf( uptrend,5 ,IIf( dwtrend,4 ,7)); // direction up down both

u1=C >O;// trigger
d1=C < O;

for(i=1;i<BarCount;i++)
  {
        if (dir[i]==5) 
Buy=d1* dir==5;
Sell=u1*dir==5;
Short=0;
Cover=0;

      

   if (dir[i]==4) 
         Buy=0;
         Sell=0;
         Short=u1*dir==4;
         Cover=d1*dir==4;

        if (dir[i]==7) 
             // BOTH
              Buy=d1* dir==7;
              Sell=u1*dir==7;
              Short=u1*dir==7;
              Cover=d1*dir==7;
}
