An MQL4 version is also available. In this MQL5 version, I added a convenient use of "+"operators and indexing "[]". "+" allows updating flags of candlestick emergence. Indexing allows checking the emergence of a candlestick of the specified timeframe.

Many MQL5 programs explicitly execute part of their code only after the appearance of a new candlestick on the chart. This class saves you from the need to write candlestick monitoring functions in each program.

To use the class, save the attached file to %TerminalPath%\MQL4\Include\ 

Include this file in the required indicator or Expert Advisor:

#include <СCheckNewCandle.mqh>

Create an object:

CCheckNewCandle candle;

// or

CCheckNewCandle candle("EURUSD");

At the beginning of the event processing function, the emergence of new candlesticks is checked (the check result is stored in an instance).

OnTick() //or OnCalculate(), or another function...
  {
  +candle;
  ...
  }  

Now, until the next check, the candle[ENUM_TIMEFRAMES timeframe] method returns the result of the previous check using the +candle; method.

if(candle[PERIOD_H1]) //Any standard timeframe.
   {
    ...
   }
if(candle[PERIOD_D1]) //Any number of requests between the calls of +candle;.
   {
    ...
   }

P.S. The +candle; call should be performed during program initialization.
