Sounds to me like you are on the US server and are getting kicked out for a few minutes over the daily reset. Note, with the shift to daylight savings, the reset has been pushed back an hour in Asia (currently 13 hour time diff to NY vs 12 last month).
If you are primarily trading Asian hours, send a help ticket asking for your account to be moved to the Asian servers where the resets take place as follows:
First reset: 16:30 - 17:00 ET (currently 5:30 AM HKT)
Second reset: 20:15 - 21:00 HKT (currently 7:15 AM ET)
noted and tks.
finally mystery solved.
