If an indicator on the five minute time frame uses a large number of bars such as 800 to 1000, will this overload the queue?
I am having a problem with an overloaded queue and the indicators appear to be the problem. Notice the gap in time between 07:46:43 and 08:02:58 when calculating indicators in the 5 minute time frame.
08:02:58 jTest 2.35 onBar(eEntry)- 03.03_03:02:58 469
08:02:58 jTest 2.35 onBar(M5x)- 03.03_03:02:58 449 <-----ending of calcs
07:46:43 jTest 2.35 onBar(M5e)- 03.03_02:46:43 707 <-----begin calcs on M5
07:46:43 jTest 2.35 onBar(M15x)- 03.03_02:46:43 647
07:46:43 jTest 2.35 onBar(M15e)- 03.03_02:46:43 647
07:45:42 jTest 2.35 onBar(xEntry)- 03.03_02:45:42 830

have you measured how long and how much resources is your calculation taking?
a 16 min. gap is massive

I moved the calculations to a separate thread and haven't seen this problem since then.
I am a bit surpirsed that JForex cannot handle a standard indicator calculation within the same thread no matter how many bars are being used. This strategy is running in MetaTrader4 without a problem.

Hi,
Normally there shouldn't be any problem with indicators calculating over a large number of bars, do you use a built-in or a custom indicator?
