EA not working

 
Hello lads, could somebody help me? I am totally novice with this.
I am just trying with tester this code and it is not working 100%, not every possible trade is executed. (I hope u can see, that I want to buy/sell when current price reaches min/max). Should I write some other conditions or something, or why it is not doing every trade?

void OnTick()
  {

   openOrder = false;
   
   //monitor open trades & place trailing stops
   for(counter=0;counter<OrdersTotal();counter++)   
   {
      OrderSelect(counter, SELECT_BY_POS, MODE_TRADES);     
      if (OrderMagicNumber() == magicNumber)
      {
         openOrder = true;
      }
   }


   if (!openOrder && Time[0] != previousSignal)
   {
      generateSignals();
      
      if (buySignal)
         placeBuy();
      else if (sellSignal)
         placeSell();
         
      previousSignal = Time[0];
   }

   
  }
//+------------------------------------------------------------------+


void generateSignals()
{
   buySignal = false;
   sellSignal = false;   
   
   min = NormalizeDouble(iLow(NULL,0,1),Digits);
   max = NormalizeDouble(iHigh(NULL,0,1),Digits);
   current = NormalizeDouble(MarketInfo(NULL,MODE_BID),Digits);
   
   if (min == current)
      buySignal = true;
   else if (max == current)
      sellSignal = true;
}

void placeBuy()
{
   RefreshRates();            
   ticket=OrderSend(Symbol(),OP_BUY,lots,Ask,slippage,NormalizeDouble(Bid - SL,Digits),NormalizeDouble(Ask + TP,Digits),"buy",magicNumber,0,Green);  
   if(ticket<0)
   {
      Print("BUY failed with error #",GetLastError()," at ",Ask);
      return;
   }
}

void placeSell()
{
   RefreshRates();            
   ticket=OrderSend(Symbol(),OP_SELL,lots,Bid,slippage,NormalizeDouble(Ask + SL,Digits),NormalizeDouble(Bid - TP,Digits),"sell",magicNumber,0,Red);  
   if(ticket<0)
   {
      Print("SELL failed with error #",GetLastError()," at ",Bid);
      return;
   }

Bid or Ask may not be exactly equal to the trigger price and may just jump over it.

So don't use

if (min == current)

use

if (min <= current)

or

if (min - current >=0 && min - current < x)

Exactly. The == operand. - MQL4 forum
