Sleep
Sleep
The function suspends execution of the current Expert Advisor or script within a specified interval.
void Sleep(
int milliseconds // interval
);Parameters
- milliseconds
[in] Delay interval in milliseconds.
Return Value
No return value.
Note
The Sleep() function can’t be called for custom indicators, because indicators are executed in the interface thread and must not slow down it. The function has the built-in check of EA halt flag every 0.1 seconds.
Example:
//+------------------------------------------------------------------+
//| Script program start function |
//+------------------------------------------------------------------+
void OnStart()
{
//--- display a countdown from 10 to 1 in the comments on the chart
for(int i=10; i>0 && !IsStopped(); i--)
{
Comment(StringFormat("Wait %u seconds",i));
Sleep(1000);
}
//--- write a text in the "arriving" comment that describes the purpose of the script
string text="This was a test showing how the Sleep() function works";
string mess="";
for(int i=0; i<(int)text.Length(); i++)
{
mess+=ShortToString(text.GetChar(i));
Sleep(100);
Comment(mess);
}
//--- say goodbye...
Sleep(1000);
for(int i=0; i<6; i++)
{
mess=(i % 2 == 0 ? "" : " Bye!");
Comment(mess);
Sleep(300);
}
//--- delete the text on the chart
Comment("");
