How to calculate number of horizontal lines(obj_hline)?

[sir7williams]

int Hlines()
        {
        int numberofhlines;
        for(int i=ObjectsTotal(0,0,0)-1;i>0;i--)                        //I cannot get correct parameters for ObjectsTotal() so I can loop through all parameters
                {
                int type=ObjectGetInteger(i,0,OBJPROP_TYPE,0);          //I cannot assign the OBJPROP_TYPE to an int "type" so i can get the type of a selected object
                if(type==OBJ_HLINE)
                   {
                   numberofhlines=numberofhlines+1;
                   }
                
                }
        return numberofhlines;
        }

Hi. I am trying to follow a function that calculates number of buy Positions that works properly, and create a function that will calculate number of HLINE objects i have on my main screen on the current chart. But I fail to get it right.

On this one, I tried to

1. Loop through all the objects on the current symbol

2. Get the type of all the objects

3. If the type of the object is HLINE, i add 1 to a variable "numberofhlines" to get the number of HLINEs. 

4. I then return the value of those HLINES. But the problem here is, i get '543 155 680' instead of the number of HLINEs i have on the screen. Please help.

Thank you very much sir. If I may ask, are there any books on MQL programming for MQL4 or 5? Besides the MQL documentation.

Posted code	int  count_hlines=0;    for(int i=ObjectsTotal(ChartID(),0,OBJ_HLINE)-1; i>=0; i--)       count_hlines++;
Simplified	int  count_hlines=ObjectsTotal(ChartID(),0,OBJ_HLINE);
