Opening a single order

[Moses Mad]

Good day, I'm not a coder, I know nothing about coding but I've managed to scrap together this script.

its pretty simple, when price is above Parabolic SAR-Buy. When Price is below Parabolic Sar-Sell.

The problem is that it opens multiple orders on the same candle.(refer to image)

Can you please help, I need it to open a single order.

#define EXPERT_MAGIC 123456   // MagicNumber of the expert

void OnTick() 
  {
  
// Create an Array for several prices
  double mySARArray[];
  
   // define the properties of the SAR
   int SARDefinition = iSAR(NULL,0,0.02,0.20 );
   
   // sort the price array from the current candle downwards 
   ArraySetAsSeries(mySARArray, true) ;
   
   // Define EA, current candle, 3 candlea,store results
   CopyBuffer(SARDefinition,0,0,3,mySARArray) ;
   
   // calculate EA for the current  candle
   double SARValue0=NormalizeDouble(mySARArray[0],5);
   
   // calculate EA for the current  candle
   double SARValue1=NormalizeDouble(mySARArray[1],5);
