I'm trying to sent http line to open position.
API description and example - https://trade4.me/API/
My Url:
https://trade4.me/order.php?username=Fib...=1&amount=1
It's demo account, you can test.

If I insert it to the browser window it works fine and I get respond:
Signal Successfully Traded : ID 11292781628, Open Price 0, Open Time 2016-12-05 19:36:36, Expiry Time 2016-12-05 19:37:36

I tried to use script from Zorro Manual example, but got message "Error during transfer!"
Also I tried to use http_send, or remove all code and leave only http_post command, but without success.
Any ideas to solve it?

Code:
void main()
{
  char ip_str[200]; // just a long empty string
  int id = http_post("https://trade4.me/order.php?username=Fiber100&password=Awainter1t&asset=EUR/USD&direction=UP&expiry=1&amount=1",0); 
  if(!id) return;
  while(!http_status(id)) 
	{
		if(!wait(100)) return; // wait for the server to reply    
		printf(".");  
	}
  if(http_status(id) > 0) 
	{	//transfer successful?
		http_result(id,ip_str,200);   //get the replied IP    
		printf("n%s",ip_str);
	} 
	else    printf("nError during transfer!");
	
  http_free(id); //always clean up the id!}
  }
