Get Open or Close Bar event

[nandocabrera87]

Dear all, hope you are fine,

I need to execute a function when current bar is closed or current bar is open.

How can I get that events?

Thank you so much!

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 ..." ); }

I just create a blog post about this, with more detailed information, to serve as a reference for users having similar queries.
