[amibroker] question on i-j; in a loop

[zeek ing]

Hello all,
So I have been studying this loop over and over again and have a problem. It
is used for sigscaleout. I am not sure what i=j does in the code. I should
say why it does what it does. When I remove the i=j in the code, then the
chart plots multiple short signals for that short. WHen the i=j is
put back in the code then only one signal is plotted. Kind of like what
EXREM does. MY question is WHY????
can anyone help??



if ( Short [ i ]  )

    {

        priceatshort = ShortPrice[ i ];

        LowsinceShort = 0;

        lowsinceshort = Min( Low[ i ], lowsinceshort );

         shortAdjusted[ i ] = 1;

        shortPriceAdjusted[ i ] = ShortPrice[ i ];

        FirstProfitTargetArrayS[ i ] =  priceatshort - FirstProfitTargetS;



        for (j = i + delay; j < BarCount; j++)

        {  LowsinceShort  = Min( Low[ j ], LowsinceShort  );

            lowSinceshortArray[ j ] = lowsinceshort;

            FirstProfitTargetArrayS[ j ] =  priceatshort -
FirstProfitTargetS;



            if( High[ j ] >= TrailStopArrayS[ j ] )

            { Cover[ j ] = 1;

                CoverPrice[ j ] = Max( Open[ j ], TrailStopArrayS[ j ] );



                i = j;

                break;   }



            if( exitType == 0 AND Low[ j ]<= (priceatshort -
FirstProfitTargetS) )

            {

              // first profit target hit - scale-out

                exitType = 1;

                ShortAdjustedScale[ j ] = sigScaleOut;

                ShortPriceAdjusted[ j ] = Min( Open[ j ], (priceatshort -
FirstProfitTargets) );

                        }



              if (j == BarCount - 1)

            { i = BarCount; }



        }

    }
