Experts: Detecting the start of a new bar or candle - page 2

Guillermo Pineda #: I've always used this code snippet to find new bars; does it function the same as your code?

You can't know when a candle closes. Only when a new tick arrives that starts a new bar is the old bar closed, and that tick could arrive almost at the end of a bar's duration.

For a new bar test, Bars is unreliable (a refresh/reconnect can change number of bars on chart), volume is unreliable (miss ticks), Price is unreliable (duplicate prices and The == operand. - MQL4 programming forum.) Always use time.

I disagree with making a new bar function, because it can only be called once per tick (second call returns false). A variable can be tested multiple times.
