New comment
 

Dears,

I need to get value of iMA from a specified time, how I do this?

thanks

 
Convert the "specified time" to a bar shift, use that in iMA

unless this is something new in mql4, I don't think that you can input datetime like that

shift = iBarShift(NULL, PERIOD_H1, 13 : 00)

You can use 

shift = iBarShift(NULL, PERIOD_H1, D'2014.03.09 13:00');
 

This is the errors

'iMA' - an operator expected C:\Program Files (x86)\FXDD Malta - MetaTrader 4\experts\indicators\teste.mq4 (16, 5)
'=' - assignment expected C:\Program Files (x86)\FXDD Malta - MetaTrader 4\experts\indicators\teste.mq4 (15, 11)
'iMA' - semicolon expected C:\Program Files (x86)\FXDD Malta - MetaTrader 4\experts\indicators\teste.mq4 (16, 5)
'}' - semicolon expected C:\Program Files (x86)\FXDD Malta - MetaTrader 4\experts\indicators\teste.mq4 (18, 1)

 

if you double click the error report line, the cursor will go to the problem area, makes them easier to find

I've inserted the missing ; I'm still not sure about the 13:00

int init() {
    //---- indicators
    shift = iBarShift(NULL, PERIOD_H1, 13 : 00) ;
    iMA(NULL, 0, 13, 8, MODE_SMMA, PRICE_MEDIAN, shift);
    //----
}
