I think ejoi made a slight mistake with the stringifying part; the code should have been like:

PHP Code:


			
double price = iMA(Symbol(),0,1,0,MODE_EMA,PRICE_CLOSE,0);



if (price=>1.0000 && price< 1.0050) 

{

sell order here

}

it seems that i also have this problem if anyone can help. i'm trying to limit the time that trades can be opened.

PHP Code:


			
total=OrdersTotal();

  if (total<1) 

   {

      

      

      if (TimeHour(CurTime())<StartHour) {return(0);}

      if (TimeMinute(CurTime())<StartMinute) {return(0);}

      

      

      if (TimeHour(CurTime())>EndHour) {return(0);}

      if (TimeMinute(CurTime())>EndMinute) {return(0);}

   }

it seems right that no trades are executed whenever i use it
my extern is as follows

PHP Code:


			
extern int StartHour=0;

extern int StartMinute=30;

extern int EndHour=22;

extern int EndMinute=30;

You might add the following function

PHP Code:


			
bool isTradableTime()

{

    datetime time = TimeCurrent();

    int now = TimeHour( time ) * 60 + TimeMinute( time );

    int begin = StartHour * 60 + StartMinute;

    int end = EndHour * 60 + EndMinute;



    return ( begin <= now && now < end );

}

and then use it like the following in your start() function

PHP Code:


			
if ( ! isTradableTime() )

    return( 0 );

If the trading period does not include midnight:

PHP Code:


			
total=OrdersTotal();

  if (total<1) 

   {

      

      if(Hour()<StartHour) return(0);

      if(Hour()==StartHour && Minute()<StartMinute) return(0);

      if(Hour()>EndHour) return(0);

      if(Hour==EndHour && Minute()>EndMinute) return(0);



   }

Dear Experts Advisors! Please give me advise on refreshing buffers (just good advise)

there is code (patch, fix, upgrade) by Raff 4 multitimeframe (MTF) indicators, working pretty good;
what could be similar code you can add to regular (not mtf) indicators?

If possible, please, give example,
thank you

//---- Refresh buffers +++++++++++++++++++++ upgrade by Raff
if (TimeFrame>Period()) {
int PerINT=TimeFrame/Period()+1;
datetime TimeArr[]; ArrayResize(TimeArr,PerINT);
ArrayCopySeries(TimeArr,MODE_TIME,Symbol(),Period( ));
for(i=0;i<PerINT+1;i++) {if (TimeArr[i]>=TimeArray[0]) {
//----
/************************************************** ***
Refresh buffers: buffer[i] = buffer[0];
************************************************** ****/

Buffer1[i]= Buffer1[0];
Buffer2[i]= Buffer2[0];
Buffer3[i]= Buffer3[0];

//----
} } }
//+++++++++++++++++++++++++++++++++++++++++ Raff ++++++

What is the proper way to put a pause statement in an EA? Would it be the same for an indicator??

sleep(1000);

1000 is 1000 milliseconds, or 1 second.
