Indicator which shows the open und close time for all important stock exchanges like NASDAC, Europe, Japan, etc.

[24h-worker]

In germany we have summer and winter time, the mql broker has also an extra time and the expert advisor uses the time of my computer for automatic trading. 

I think an indicator that shows when an stock exchange opens and closes is an important tool that Metratrader should still include.  This indicator can then be accessed by the Expert Advisor.

For example, the indicator returns -1 when the stock exchange is closed and +1 when it is opened. For a better overview, the return codes could be set individually for each exchange.

Example:

int var_Stock_Exchange = iStock(_Symbol, PERIOD_H1, 0,0);  // 0 = NASDAC,    1 = Frankfurt,   2 = Japan, 3 = Moscow  etc.
