Hi,
Years ago I tried to do this with a market trading times tool and from memory ( as In cannot for the life of me find the tool ) I used a comparision between the Broker and Local time and if there was more than 5 minutes difference in the time offset it signalled that the markets had either closed or the platform was off line. The idea behind this was that the Broker time stops updating when the market closes and the Local time keeps ticking on. Hope this helps.
This could be a winner - as long as the ea is being feed fake ticks.
Else the ea doesn't get to action the comparison of the 2 times. It will just sit still and waiting.

cheers scalpz

I think that the best would be to use SymbolInfoTick(...). that includes the date of the last tick. So if this is more than xx seconds ago, the market is either closed or very slow and no for trading.

Just found this thread as I'd like to do what the initiator clearly stated in the first post and am amused at the pompous replies from people who are obviously wonderful programmers but can't understand plain English
The market doesn't just close on a Friday, it closes for public holidays as well, and making sure that any pending orders are closed or that a period of data gathering is contiguous could be the difference between profit and loss.
I'm sure it can't be too difficult but the answer is not here; if I find it I'll try to remember to come back...

Best wishes, Geoff

The general and universal solution to this problem is not so difficult:

  1. Read the gemeral trade session times from market info. This includes general trading times and futures markets session breaks.
  2. Read the specific trade session times from an external configuration (e.g. a text file). This includes regular holidays (Christmas, New Year) and extraordinary holidays (bank holidays etc.) which are not covered by the data available via market info.
  3. Merge both to determine the trade session times of the actual current day.
  4. Calculate the next start and the next end of a trade session pause/break.
  5. Set a time condition of - say - 1 minute before the start of the next session break (I use 1 minute before trade session end and 10 seconds after trade session start).
  6. Monitor that limit and do what you want to do.
  7. To make sure the EA operates with a stalled data feed or when starting during a session break (weekend) setup a virtual ticker (I use one tick every 10 seconds).

Whenever monitored time surpasses the begin of the next trade session I recalculate the session break times for the next break. This way calculation of session break times happens only once a day. The important point here is to not use the time of the last tick for comparisons (last tick time will not change after the market stops ticking) but to use real computer time and convert it to server time which may be different due to different timezones. So one needs to know the timeshift between broker and local time.

ps: All of this could already be done at the time of thread start with old MQL4 (without post build 600 features).

What does an external general and specific trade session configuration look like:
Inserted Code
[TradeSessions]                                 ; All times are server times.
Monday     = 00:00-24:00                        ; full trade sessions
Tuesday    = 00:00-24:00
Wednesday  = 00:00-24:00
Thursday   = 00:00-24:00
Friday     = 00:00-24:00
Saturday   =                                    ; empty: no trade session
Sunday     =
 
2019.01.01 =                                    ; standard holidays
2019.12.25 =
 
{symbol}.Monday     = 03:00-12:10, 13:30-19:00  ; multiple trade sessions (e.g. futures)
{symbol}.2019.07.04 = 01:02-20:00               ; a limited trade session (e.g. Independence Day)
{symbol}.2011.11.11 =                           ; a symbol-specific holiday
It takes blood, sweat and enough tears to wash away the blood.
