Why iTime is showing 1970.01.01 on new chart.

[Michal Adam Ciechanowicz]

Hi Guys 

Can someone explain why whenever I have a new chart opened and run iTime(Symbol(),PERIOD_D1,0) or  iTime(Symbol(),PERIOD_D1,1)

for the first time. I always got 1970.01.01. TimeCurrent() is showing good time, straight away.

Did you read the documentation ?

Return Value

The opening time of the bar (indicated by the 'shift' parameter) on the corresponding chart or 0 in case of an error. For error details, call the GetLastError() function.

Note

The function always returns actual data. For this purpose it performs a request to the timeseries for the specified symbol/period during each call. This means that if there is no ready data during the first function call, some time may be taken to prepare the result.

The function does not store previous calls results, and there is no local cache for quick value return.

its perhaps due to available bars not synchronized , check with

datetime d1 = D'1970.01.01';
if(iTime(Symbol(),PERIOD_D1,0) ==  d1)
Print(GetLastError());

On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

On MT5: Unless the current chart is that specific pair/TF, you must synchronize the terminal Data from the Server before accessing candle/indicator values.
