Hi,

I'm getting this message, when market is closed (weekend), and strategy runs
during the weekend:

11:51:45 Strategy thread queue overloaded with tasks. Ticks in queue - 0, bars - 2883, other tasks - 784


I thought it means, that strategy is to slow in handling each tick, but on the weekend
there are no new ticks ???

Thx
DT

@quantisan: No, I only compute values for the COG-Indicator and then check some
entry conditions about crossing the COG-lines. If an order is in the market I manage
the open orders for reverse signals .... it is quite simple ... so I wonder abouht this
messages.

BTW: With API-Version 2.6.38 since this yesterday there are no new messages.
Maybe the team has fixed some errors?

Ok, new messages occured this night with new API-Version 2.6.38.
I looked at the code again and found some waitForUpdate() after
sending my order (incl. stop, profittarget).

Now I removed waitForUpdate() completeley and wait for new messages.

This thread overload issue is very, very hard to get and hard to program.
Other users get this issue too and I think support need something to clarify here ...

This message means that strategy thread can't process messages it receives. Most likely you block it in one of the IStrategy methods. If you have some lengthy jobs - start your own thread

Yes, during the weekend the JForex platform doesn't receive tick, you can filter this days.
