My theory of iSAR and iAO in a custom indicator but I cant get it to work as an EA

New comment
 

Hello,

I have written a custom indicator that uses the switch of parabolic sar and awesome indicator to show me when to enter a trade, I have been trying to put the code into a EA with no luck, any help would be most appreciated.

I have tried a few ways of putting it into an EA, by copying and pasting the code while changing ExtVigTheoryBuffer to a buy orderSend command but it ends up buying multiple times on the same candle. When i try calling the custom indicator, it slows down to a snail and never enters.

How would you suggest that I test my theory? Also any criticism of the actual theory are welcome.

#property indicator_separate_window

// Set static height of indicator graph
#property indicator_minimum -1.2
#property indicator_maximum 1.2

// Set colors for two indicators
#property indicator_color1 Red

extern double Step =0.09; //Parabolic setting
extern double Maximum =0.2; //Parabolic setting

double ExtVigTheoryBuffer[];

//+------------------------------------------------------------------+
//| Custom indicator initialization function |
//+------------------------------------------------------------------+
int init()
{
//---- indicators
SetIndexStyle(0,DRAW_ARROW);
SetIndexArrow(0,115);
SetIndexBuffer(0,ExtVigTheoryBuffer);
//----
return(0);
}

//+------------------------------------------------------------------+
//| Custom indicator iteration function |
//+------------------------------------------------------------------+
int start()
{

// Go through all the candlesticks, determine whether to buy, sell or do nothing
// at each point
for (int i = 0; i < Bars; i++){

// Get difference in Awesomeness for current and previous values
double aoDiff = iAO(NULL, 0, i) - iAO(NULL, 0, i+1);

// If Stop and Reverse changes from above curve to below curve,
// and awesomeness is "green", start buying
if (iSAR(NULL, 0,Step,Maximum, i) < iLow(NULL,0,i)
&& iSAR(NULL, 0, Step, Maximum, i+1) > iHigh(NULL, 0, i+1)
&& aoDiff >= 0)
{
ExtVigTheoryBuffer[i] = 1.0;
}

// if Stop and Reverse is changes from below the curve to above the curve
// and awesomeness is "red", start selling
else if (iSAR(NULL, 0,Step,Maximum, i) > iHigh(NULL,0,i)
&& iSAR(NULL, 0,Step,Maximum, i+1) < iLow(NULL,0,i+1)
&& aoDiff <= 0 )

{
ExtVigTheoryBuffer[i] = -1.0;
}

}

return(0);
}

  2. I have written a custom indicator that uses the switch of parabolic sar and awesome indicator to show me when to enter a trade, I have been trying to put the code into a EA with no luck, any help would be most appreciated.

    The indicator recalculates every pixel for each tick - use IndicatorCounted Multiple Null Bar Re-Count in Some Indicators

  3. Where's your EA code. Did you use Icustom or did you paste the code, forget to remove the i<Bars loop with i=0
 

Thank you William for such a quick reply.

I tried putting this into an EA which fails miserably :

#property indicator_separate_window

// Set static height of indicator graph
#property indicator_minimum -1.2
#property indicator_maximum 1.2

// Set colors for two indicators
#property indicator_color1 Red

extern double Step    =0.09;   //Parabolic setting
extern double Maximum =0.2;    //Parabolic setting

double ExtVigTheoryBuffer[];

//+------------------------------------------------------------------+

//+------------------------------------------------------------------+
int init()
  {
//---- indicators
   SetIndexStyle(0,DRAW_ARROW);

//----
   return(0);
  }
//+------------------------------------------------------------------+

int start()
 
 {

      int MaxBar, limit, counted_bars = IndicatorCounted();
//---- check for possible errors
   if(counted_bars < 0)
       return(-1);
//---- the last counted bar must be re-counted
   if(counted_bars > 0) 
       counted_bars--;

//     all bars will be re-counted

//---- determining of the oldest bar number, starting from which

     {
       for(int bar = Bars - 1; bar >= limit; bar--)
           MapBuffer[bar] = 0.0;
       limit = MaxBar; 
     }
*/
      // Get difference in Awesomeness for current and previous values
      double aoDiff = iAO(NULL, 0, 0) - iAO(NULL, 0, 1);
      
      // If Stop and Reverse changes from above curve to below curve,

            int buy = OrderSend(Symbol(),OP_BUY,1,Ask,5,Ask-30*Point,Ask+50*Point,0,0,0,Green);
            return;
          }
      
      // if Stop and Reverse is changes from below the curve to above the curve
      // and awesomeness is "red", start selling
      else if (iSAR(NULL, 0,Step,Maximum, 0) > iHigh(NULL,0,0)
               && iSAR(NULL, 0,Step,Maximum, 1) < iLow(NULL,0,1)
               && aoDiff <= 0 )
      
         {
            int red = OrderSend(Symbol(),OP_SELL,1,Bid,5,Bid+30*Point,Bid-50*Point,0,0,0,Red);
           return;
         }
      
   

return(0);
}

I tried to add the code from the Multiple Null Bar Re-counted with no luck so i /* */ that code as i didn't totally understand how the code worked. I feel that I have made a really basic mistake but I just can't see it.

Thanks again William

1) Your code is a indicators, and indicators are not allowed to trade.

2) the start() function is called every tick. so when your conditions are true, every tick a new order is sendet.

open editor, create a empty Expert Advisor.

-search here in the forum on how to limit the EA to trade only once per Bar.

-search how to modify the EA that it supports 4/5 digit brokers

this are the main mistakes you have made, i have not looked in detail at your code, so there maybe some other logical error, for now try to build a very basic EA, not a Indicator
