Hi,

It seems that subscribing to more than 5-6 Instruments on the Remote Server is causing a "Max overload period exceeded : 60 seconds" error and the strategy can never start up....

See the test code attached which tries to subscribe to 11 Instruments and gets stopped.

Is it by design so or my code has a bug?

On my local machine I can see no CPU usage increase while running this strategy at any time.

There is not need to pause for 1 second between the subscription requests.

Do not subscribe for custom period of 15mins as minutes periods will be coming in onBar() method after subscribing to a full market depth anyway.

Attached is the updated strategy.

Thanks for your hint but I get the same issue with this as well...see the code attached.

It seems there is something with the remote server CPU restrictions.

What can be done from your side:
1. Divide the amount of subscribed instruments into 2 strategies run remotely, if possibe.
2. Subscribe with time intervals between each of the instruments.

We will try to improve this on our side in the future.

I had improved the code with some threading so that I managed to subscribe to max 11 instruments but at the first run the onBar function burned the CPU as well....

BTW Jforex allows me to run only one strategy on the remote server at the same time...

Please enhance the CPU power so that one can use multi-instruments strategies as well. Thanks!
