Stop / kill calculating a function. - page 2

Please make sure you understand the use of the function.

Call by the first position and the number of required elements
int  CopyRates( 
   string           symbol_name,       // symbol name 
   ENUM_TIMEFRAMES  timeframe,         // period 
   int              start_pos,         // start position 
   int              count,             // data count to copy 
   MqlRates         rates_array[]      // target array to copy 
   );
Call by the start date and the number of required elements
int  CopyRates( 
   string           symbol_name,       // symbol name 
   ENUM_TIMEFRAMES  timeframe,         // period 
   datetime         start_time,        // start date and time 
   int              count,             // data count to copy 
   MqlRates         rates_array[]      // target array to copy 
   );

Call by the start and end dates of a required time interval
int  CopyRates( 
   string           symbol_name,       // symbol name 
   ENUM_TIMEFRAMES  timeframe,         // period 
   datetime         start_time,        // start date and time 
   datetime         stop_time,         // end date and time 
   MqlRates         rates_array[]      // target array to copy 
   );
 
Thank you.
I will take a look on it next week.

Regards.
 
Marco vd Heijden:

Please make sure you understand the use of the function.

So i can set all the parameters (datetime, int, ...etc) to NULL according the "true/false" state of my button (?).
Thank you for your help.

  
double m_MN1[][6];
ArrayCopyRates(m_MN1,Symbol(),PERIOD_MN1);

This is incorrect use of the function.

If you look at my examples above you can see that the first parameter is symbol_name followed by timeframe, then the start and stop positions and finally the target array.

 
Here is the original indicator (not mine), that i have modified later.
How can I nullify all the parameters ?
