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. A variable can be tested multiple times. New candle - MQL4 programming forum #3 2014.04.04
