Trade Sessions Indicator - indicator for MetaTrader 5

This indicator is based on DRAW_FILLING buffers.

The input parameters are absent, the TimeTradeServer(), TimeGMT() functions are used.

The unaccuracy in the trade session times is possible, the values are from the first site I have found :))

It is possible to change its values in the block of constants, the GMT time is used.

// Time constants are specified across Greenwich
const int   AsiaOpen=0;
const int   AsiaClose=9;
const int   AsiaOpenSummertime=1;   // The Asian session shifts
const int   AsiaCloseSummertime=10; // after the time changes
const int   EuropaOpen=6;
const int   EuropaClose=15;
const int   AmericaOpen=13;
const int   AmericaClose=22;

There is an opportunity to use the time changes to the summer time, at present time it's a primitive and realized with the function TimeDaylightSavings();

//+--------------------------------------------------------------------+
// Summertime determination is reserved for the future calculations
//+--------------------------------------------------------------------+
bool Summertime(datetime time)
{
   if(TimeDaylightSavings()!=0)
      return(true);
   else
      return(false);
} 

So, after the time change to the summer time, all of the history changes it's time and vice versa.

The first version of the indicator has been published at MQL4
