Question for any good Coders

I have an indicator that I want to find out how often it reaches a certain level.

I use the for loop; for(int i=1;i<limit;i++) - To get the bar count.
Lets say the indicator I have goes from -10 through to +10. And I want to find out how many times it reached +9 or more for say 48 bars. Is it possible to code this? The way I would think it would be done is by using the result I get from the indicator, and doing a if statement. So if(Result => 9){ int average = 1;}
But when I do this if the value of result did reach 9 or more it just displays number 1, and doesnt count it.
So lets say there are 48 bars I want to find out how often it reaches that level. Somehow it needs add 1 for each time it reaches 9 +. So the indicator reaches 9 or more, 10 times over that 48 bar period, i need to get that result.
Any help greatly appreciated.

On re-thinking i think I need to use ++ to get it to add to the last result so that it counts. so ( result++).

Yes, increment your counter variable w/ ++ every time your indicator-condition is satisfied.

Then check your counter value as part of your trigger-condition logic.

Thanks Dave for your help. When you say check the counter value, do you just mean to call its value up? i.e. print ' counter value '. Im not looking for it to make a trade decision, its just to gather some data.
For some reason its not counting up. Here is my code, the figures Iv used are different to what I said but it was to make it easier to understand.

double COUNTER = 0.01;

if(ExtMapBuffer2[i] >= 0.015)
{
COUNTER++;

}
ExtMapBuffer3[i] = COUNTER;

Inserted Code
 
int [b]COUNTER [/b]= 0;
int NBarsLookBack=10; // number of bars to look back for value criteria
int NThreshold=5;        // the counter number to exceed (or equal or whatever)
                               // to qualify for your condition
 
for(int i=0;i<=NBarsLookBack;i++)
{
 if(ExtMapBuffer[b]2[/b][i] >= 0.015)
 {
[b]  COUNTER[/b]++;
 }
}
 
if([b]COUNTER [/b]>= NThreshold) 
{
 ... your commands ...
}

So, what the above code does is increment the Counter variable every time ExtMapBuffer2 exceeds 0.015 within the last 10 bars (or whatever you set for NBarsLookBack).

Then, after it has done checking the last 10 bars, if your Counter variable exceeds 5 (or whatever your NThreshold is set to be), which is to say, if ExtMapBuffer2 exceeded 0.015 in at least 5 of the past 10 bars, execute whatever other subsequent commands you want.

Awesome Dave! I was on the right tracks at least.
Its strange though but just demostrates how the bars are calculated, from the start bar to the end bar! So my line i get is actually counting down and reaches zero at the end! very wierd. Anyway I can sort that little thing out,
thanks again matey.

No problem, fry.
Yes, bar 0 is the current (unformed bar), and the number increases as you go to the left (past) of the chart.
