for(int i=0;i<=1440;i++)
     {
      datetime bar_time=iTime(NULL,0,i);
      if(bar_time==0) Print(__FUNCTION__+": iTime failed. Error=",GetLastError());

Why do I always get bar_time 0 and error 4051?

Hello,

I have a link: http://bhashsms.com/api/sendmsg.php?user=userid&pass=userpass&sender=senderid&phone=mobile&text=alertmessage&priority=ndnd&stype=normal

This link sends a text message to your phone if you fill in your username, password and other fields. The link works by inserting it into the browser.

I'm trying to do it like this:

void SMSapi(string userID,string password,string senderID,string phone,string text) 
  { 
   int    res;     
   char   data[];  

   string str="user="+userID+
              "&pass="+password+
              "&sender="+senderID+
              "&phone="+phone+
              "&text="+text+
              "&priority=ndnd&stype=normal"; 

   ArrayResize(data,StringToCharArray(str,data,0,WHOLE_ARRAY,CP_UTF8)-1); 

   res=WebRequest("GET","http://bhashsms.com/api/sendmsg.php",NULL,0,data,data,str); 
   Print(res);
}

But the result = -1. I read that if "...sendmsg.php?..." link has "?" sign in it, it should be "GET" request, I tried the same "POST" request but the result is negative.

Please help me to make a correct request.

Thank you.

In iTime, is the indexing not like in timeseries? Not backwards (the newest bar is zero)?

I have also tried a different request:

void SMSapi_2(string userID,string password,string senderID,string phone,string text){ 
  
   string cookie=NULL, headers;
   char post[],result[]; 
   int res; 
   int timeout=5000; 
   char   data[];  

   string str="user="+userID+
              "&pass="+password+
              "&sender="+senderID+
              "&phone="+phone+
              "&text="+text+
              "&priority=ndnd&stype=normal"; 
              
   string url="http://bhashsms.com/api/sendmsg.php?"+str;

   res=WebRequest("GET",url,cookie,NULL,timeout,post,0,result,headers);   

   Print(res);
}

does not work, the result is negative.

   Alert("Бар = ", i, "  bar_time = ",iTime(NULL,0,i));

In any case there will be a problem if you start the test in the current month and use PERIOD_MN1. I wrote about this in post #2429.

Remind me. I'll try to reproduce it.

(Just give me the link).
