No waiting for next 'tick'?

int start(){
   while(!IsStopped()){ 
      RefreshRates();

      ...// everything else goes here.

      Sleep(1000);
   } // while
   return(0);
}

Can't be an indicator as they can not sleep.

thanks for this - I did try this in an indicator and as you say it doesn't work. I guess there is no solution for an indicator then?

Also, I guess it is not possible to do anything in code with cursor/crosshair data in EA, indicator etc;??

thanks

Don't the cross hairs do this for you or do you want to do something more complex than just get a price from a chart?

Look for:

void start()

if(Volume[0]>0)return(0); //<----remove this line

yes, I want to be able to determine s/r levels dynamically by using the price values given by the crosshairs. So if I can utilise the price values from the cross hairs in code then this would be the ultimate solution.

please can you expand further - I don't have his code in my routine, should I include the void start() block?

sorry - I misunderstood your question.

you have suggested

void start()

if(Volume[0]>0)return(0); //<----remove this line

where do i find this line to remove it?

if you have that line in a script it will only run the script every bar count - eg: if your bar count is 1 minute then the script will run once every minute. If you take that line out then it will run every time there is a trade.
