this code is from   https://docs.mql4.com/series/itime

Print("Current bar for USDCHF M5: ",iTime("USDCHF",PERIOD_M5,0),", ",  iOpen("USDCHF",PERIOD_M5,0),", ",
                                      iHigh("USDCHF",PERIOD_M5,0),", ",  iLow("USDCHF",PERIOD_M5,0),", ",
                                      iClose("USDCHF",PERIOD_M5,0),", ", iVolume("USDCHF",PERIOD_M5,0));

rjngh2005: The following code does not work - please help

Just saying it "does not work" means nothing. We have no idea what you mean by it, nor can we see what you expect.

Explain in detail, provide screenshots and show the output from the logs.

EDIT: Also, please note that when acquiring data from a different time-frame from the one being tested you have to synchronise the data and handle 4066/4073 errors.

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.

Here is the ouptput I get when i run the code in live/strategy tester   (m1) i am expecting some values for the m5

Current bar for XAUUSD M5: 1970.01.01 00:00:00, 0.0, 0.0, 0.0, 0.0, 0

[rjngh2005]

If i remember right, that farthest date allowed in mt4 is not fixed, it is actually a maximum number of candles, so I remember a thread only recently, in last 10 days, where the op mentioned 1976 was the earliest date that he could get. And I think that the moderator mentioned that even this date will become invalid as this earliest date continues to move forward.

Did you correct your code according to the advice given in my post?

Also, please note that when acquiring data from a different time-frame from the one being tested you have to synchronise the data and handle 4066/4073 errors.

The 4066/4073 errors don't appear in the logs. You have to process them just as indicated. Follow the links and read up on how to process them.
