WHRoeder:
You misunderstood. He was using the variable i for BOTH the current chart AND the D1 chart.

I see your point now. He should have separated apple and orange = don't use the same i.

ledzep:

ledzep, why you have use this condition?

Isn't it always true?

Thanks for your reply.

int start()
  {
   static bool first=true;  

   ...

if(counted_bars==0 || first)
      {
      first=false; 
      ...
      }

That's something I didn't get until quite recently . . . static variables get initialised only once not every time the function they are in is called. https://docs.mql4.com/basis/variables/static

Along those lines, have anyone else noticed that global scale bools (not terminal global) don't save their values between function calls? Or is it just me ... I haven't really tested it extensively, I'm hoping to get a quick confirmation.

I hope it's just you . . otherwise my extern bools wouldn't be doing what they seem to be doing. ;-)

Now I really have to go test this. I've put it off long enough ;)

Update: they all worked!! Yeaaa. I must have had a logical issue when I dealt with it back-then. I've just got-by on using integers. This outta help shorten, optimize and save some resources.

Statics get initialized only once on load. They do not get reinitialized on each deInit/Init cycle. This it my pattern for initialized globals/statics, statics become global as they are now shared between OnInitX() and X()

int start(){    static bool first=true;    :    if(counted_bars==0 || first)       {       first=false;       ...       }	int init(){    OnInitStart();    : } bool first; void OnInitStart(){ first=true; } int start(){    :    if(counted_bars==0 || first)       {       first=false;       ...       }
