George Johnson: what is the best code for identifying a new bar ??
This code will work on both MQL4 and MQL5:
// Check for New Bar static datetime dtBarCurrent = WRONG_VALUE; datetime dtBarPrevious = dtBarCurrent; dtBarCurrent = (datetime) SeriesInfoInteger( _Symbol, _Period, SERIES_LASTBAR_DATE ); bool boolNewBarFlag = ( dtBarCurrent != dtBarPrevious ); if( boolNewBarFlag ) { Print( "... do something ..." ); }
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.
