Bar shift issue, why this happen?

New comment

In the first code the condition open_b is verified, in the second never. The only difference is the bar shift, I need one more condition on the 0 bar so I incremented the bar by 1. Why this happen?


CODE 1:
//--------------Trading criteria------------------------------------------------- 5 --
  
    double open0 = iOpen(NULL,0,0);
    double close0 = iClose(NULL,0,0);
    double high0 = iHigh(NULL,0,0);
    double low0 = iLow(NULL,0,0);
    
    double open1 = iOpen(NULL,0,1);
    double close1 = iClose(NULL,0,1);
    
    double open2 = iOpen(NULL,0,2);
    double close2 = iClose(NULL,0,2);

    double open3 = iOpen(NULL,0,3);
    double close3 = iClose(NULL,0,3);
    
    double open4 = iOpen(NULL,0,4);
    double close4 = iClose(NULL,0,4);
    
    double open5 = iOpen(NULL,0,5);
    double close5 = iClose(NULL,0,5);

if (
    Ask<iBands(NULL,0,20,2,0,PRICE_MEDIAN,MODE_MAIN,0) &&   // price minore di linea media bollinger
    close4 < open4 &&                                       // down bar 4
    close3 < open3 &&                                       // down bar 3
    close2 < open2 &&                                       // down bar 2
    close1 < open1 &&                                       // down bar 1
    close3 > close2 &&                                      // down trend
    close2 > close1 &&                                      // down trend
    MathAbs(close0 - open0) < VolumeDoji * Point &&         // DOJI minore di...
    (
        (close0 > open0 && open0 - low0 > OMBRAlow * Point && high0 - close0 < OMBRAhigh * Point && MathAbs(open0 - low0) > MathAbs(close0 - open0)) ||  // Candela verde (up), low grande, high piccolo, ombra piu lunga del corpo
        (close0 < open0 && close0 - low0 > OMBRAlow * Point && high0 - open0 < OMBRAhigh * Point && MathAbs(close0 - low0) > MathAbs(close0 - open0))    // Candela rossa (down), low grande, high piccolo, ombra piu lunga del corpo
    )
   )
{
    Opn_B = true;
}

    double open1 = iOpen(NULL,0,1);
    double close1 = iClose(NULL,0,1);
    double high1 = iHigh(NULL,0,1);
    double low1 = iLow(NULL,0,1);
    
    double open2 = iOpen(NULL,0,2);
    double close2 = iClose(NULL,0,2);

    double open3 = iOpen(NULL,0,3);
    double close3 = iClose(NULL,0,3);
    
    double open4 = iOpen(NULL,0,4);
    double close4 = iClose(NULL,0,4);
    
    double open5 = iOpen(NULL,0,5);
    double close5 = iClose(NULL,0,5);

    Ask < iBands(NULL,0,20,2,0,PRICE_MEDIAN,MODE_MAIN,1) &&   // price minore di linea media bollinger

    Opn_B = true;
