Simple Help with iBarShift Please

Either my brain is not working (more than possible!) or I cannot get iBarShift to work on daily data pre about Aug 2005 which is about 3130 daily bars and I want to reference much earlier bars.
If I force a daily time with an index of more than this the result comes back as 1970

Is there a limit to the number on iBarShift ????

Thanks,

M.

Weird ... I tested and I can go past 7,000 bars with correct results.

Tested on H1 ... my daily datas is available only for 9 years 2,500 bars (sept. 2008).

Thanks for answer.
Almost certainly something I have coded wrong but cannot see it.

AHaa !!! checked and only daily data back to that time :-(
Had not considered that one.

Thanks for the heads up.

Maybe you need more Max bars in history. Check Mt4/Options/Charts, try this number 2147483647 and restart MT4.

Saronko,

Thanks for input, appreciated.
(Ferru already pointed me in that direction)
