There were some problems with SERIES_LASTBAR_DATE. It was discussed here somewhere long ago. Maybe it was fixed.
The iXXX() function works fine, I've been using it for about 3 months (since I started using MQL5) - I haven't noticed any bugs or... - It's very handy and everything works!
SZZY: it works as written in Help :
Parameters
symbol
[in] Instrument symbol name. NULL means current symbol.
timeframe
[in] Period. Can be one of values of enumeration ENUM_TIMEFRAMES. 0 means period of current chart.
Do you always just write and don't try to read? I gave you a link to a whole article about the New Bar! Articles are checked - checked by people of a different competence than those who write constantly on the forum ;)
ZS: If you stop writing and start reading, such as the article on my link, you can find another way ( SERIES_LASTBAR_DATE ) not to use the iXXX() - I told you not to use them ))) - who would tell the bugs and errors that the developers released shoddy )))))
I converted many MT4 EAs to MT5 without modifying source code. I posted the sabot as Open[i].
Ever done performance measurements between CopyXXX and iXXX functions? This question is very interesting.
So far I see one obvious convenient use of iXXX functions - less remaking of MQL4 code when porting it to MQL5.
In other cases (without knowledge of performance) - the choice is based only on users preferences.
Sabz in the form of Open[i] posted.
Didn't pay attention to this code, checked it - it works!
ZS: I need to see how I got [] tomorrow when I have a clear head - I tried it several times - it didn't work for me!
Ever done performance measurements between CopyXXX and iXXX functions? Very interested in this question.
I haven't. I very rarely deal with bars. Nothing should be faster than CopyXXX functions. Only if you cache it.
