You need to write loop using PositionsTotal() and then examine the position type of each position, depending whether it is buy or sell you can add them up.

void OnTick()
  {
  
   Comment("Buy Count : ", buy_count , "\n",
           "Sell Count : ", sell_count , "\n" );
   
   for(int i=PositionsTotal()-1 ; i <= 0 ; i-- )
     {

      if( PositionSelect(_Symbol) == POSITION_TYPE_BUY )
        {
         buy_count++;
        }
      if( PositionSelect(_Symbol) == POSITION_TYPE_SELL)
        {
         sell_count++;
        }

 Thank You... sir (+1 Respect From Me To You)

still i have some questions sir  Can You Please clear my doubts??

Q.1 > why did you again initialize buy_count =0; sell_count=0;  inside the ontick funtions??? how its effecting ?? 

Q.2 >  when i comment out PositionGetTicket(i); it don't work, how its contributing here?? is it someting line ArraySetAsSeries()??

Please Suggest Me Some books ?? and good beginers/intermediat mql5 articles and books which i should definitely read

A1. Comment them out and see the result - you will get ever increasing incorrect numbers with each new tick

A2. Read the documentation - this function must be used to select a ticket's data so it can be read correctly

PositionGetTicket(i);  doubt is clear now, it's selecting the i 'th no. of open positions and getting ticket no. of that i and auto selecting and keeping it for next operating to done with it.. 

but.. i have still some doubt relating to variables like how its working ??

like first it initialized in globally right..

int buy_count = 0;
int sell_count = 0;

then why i reinitialized it inside the ontick function?? 

void OnTick()
  {
   buy_count = 0;   sell_count = 0;      // 

and when the for loop is running ... its adding to local variable or global variable???

for(int i = PositionsTotal() - 1 ; i >= 0 ; i--)   //#2 not i <= 0 
     {
     PositionGetTicket(i);                            //#3 Missing PositionGetTicket(i);    
     
      if(PositionGetInteger(POSITION_TYPE) == POSITION_TYPE_BUY) //#4 not PositionSelect(_Symbol)
        {
         buy_count++;
        }
      if(PositionGetInteger(POSITION_TYPE) == POSITION_TYPE_SELL) //#4 not PositionSelect(_Symbol)
        {
         sell_count++;
        }

and it comment() is taking buy_count from local variable or global variable?

   Comment("\n\n\n\n\n",
            "Buy Count : ", buy_count, "\n",
           "Sell Count : ", sell_count, "\n");

can you please explain the whole process step by step ????

[R4tna C]

All references inside OnTick() are to the global variables, so you have to initialize them on each tick, otherwise you will get ever increasing numbers.

There are no local variables defined inside OnTick().

If that is not clear, comment out the line and you will see the numbers increase with every tick

   buy_count = 0;   sell_count = 0;      //
