在出现在图MQL5上之前预测分形

Question

I am trying to predict the fractal values before they appear on the chart so that I can apply other algorithms. I have tried the following but is of no use as it is giving the false positive to me.:

int fractalStore;
int OnInit()
{
   fractalStore = iFractals( _Symbol, _Period );
   ArraySetAsSeries( UpFrac,  false );
   ArraySetAsSeries( DownFrac,false );

   return( INIT_SUCCEEDED );
}

void OnTick()
{
     CopyBuffer( fractalStore, 0, 0, 5, UpFrac   );
     CopyBuffer( fractalStore, 1, 0, 5, DownFrac );

     if (  ( UpFrac[  0] != UpFrac[  1] )
        && ( DownFrac[0] == DownFrac[1] )
        && ( UpFrac[  0] == DownFrac[1] )
        && ( UpFrac[  0] == DownFrac[0] )
           )
     {
         trade.Buy( 0.1 );
         if ( !ArrowBuyCreate( 0, "Arrow Buy" + IntegerToString( count ) ) )
               Print( "Cannot sell" );              
     }

     if (  ( DownFrac[0] != DownFrac[1] )
        && ( UpFrac[  0] == UpFrac[  1] )
        && ( UpFrac[  1] == DownFrac[0] )
        && ( UpFrac[  0] == DownFrac[0] )
           )
     {
           trade.Sell( 0.1 );
           ArrowUpCreate();

           if (  !ArrowSellCreate( 0, "Arrow Sell" + IntegerToString( count ) ) )
                  Print( "Cannot sell" );

           Comment( "Sell" );
       }
}

I am trying to predict the values of Fractal arrows and display them. But getting very different values and placing the arrows else where.

Kindly, help me and let me know how I can predict the arrows of the fractal before actual indicator placing the arrow.

Answer 1

One who has read a definition of Fractal knows this will never fly

By design, there is at least a 3 Bar principal detection lag, before one can confirm a presence of Fractal-based signal.

As simple as this.
