need help in counting bars

New comment
 

int i;

int int()

   i=0; 

int start()

  if(i<Bars) i++; 

 problem is  when i use "every tick mode" on tester i++ is not synchronize to bar counting, but when i use "open price mode" it is synchronize. can anybody explain to me whats the problem?

   Bars.       int Bars
Number of bars in the current chart.

 if(i != Bars) i=Bars;

thanks for the help.. i already try that code but this code continues counting bars, i need " i " to reset to zero in a certain count of bars so that i'm trying to use i++.

if you reset i to zero in the loop then the loop will never end

The topic is  

need help in counting bars

And 
Bars

 is returning Number of bars in the current chart.

So what do you count ???   What is the problem you have ??? 

 
Search for "once per bar"

 thanks for replay.. could you check my code.. 

int start()

 {

 valHigh=Low[iHighest(symb,0,MODE_HIGH,NumBars,0)];

  if(i<Bars) i++;

  if(Close[0]>valLow+(Deviation*Point) && i>=20)

   {

    valHigh=High[iHighest(symb,0,MODE_HIGH,NumBars,0)];

    i=0;

   } 

 

the problem is when i use "every tick mode" the i++ is counting faster than bar count.

Could you, please, edit your post and use SRC button when you post code.



  
int start()
 {
 valHigh=Low[iHighest(symb,0,MODE_HIGH,NumBars,0)];
 //from bar 0 to bar NumBars you search for the bar with the highest value 
 //and then you want to know the lowest value of that same bar
  if(i<Bars) i++;//now i get the same value as total of bars you have on CHART_BAR
                 //every new tick i get value +1 until i is equal to the count of 
                 //bars of your chart
  if(Close[0]>valLow+(Deviation*Point) && i>=20)
  //valLow  variable looks not to be defined
  //normally after 20 ticks i always greater or equal as 20
  //Close[0] is same as Bid
   {
    valHigh=High[iHighest(symb,0,MODE_HIGH,NumBars,0)];
       //now valHigh becomes the highest value of bar 0 till bar number NumBars
    i=0;// and you reset i to zero when Close[0]>valLow+(Deviation*Point) 
        // but with next tick valHigh will become again
        // valHigh=Low[iHighest(symb,0,MODE_HIGH,NumBars,0)];
So this is not counting bars....

please check again my code.. thanks for your time.. 

 when i use this code " if(i<Bars) i++; " i++ is stuck in one.

if i use this code " if(i!=Bars) i++; " i++ is counting faster than bars count. 

When i use "open price mode" i++ is synchronize to bars count, but if "every tick mode" i++ is counting faster than bars count. 

 

will look later to the code 

but this 

  if(Bid<10) int digit=5;
   else digit=3;

 is not a reliable code for having it work as well on all brokers it will fail several Symbols

what timeframe is it you do use this code ??
