Hi, I am running Zorro S 1.50 and I am live trading using Oanda v1 plugin.

I always get this error message during busy market hours:
"!Rate limit violation of newly established connections. Allowed rate: 2 connections per second"
It seems when market is quiet the error may go away.

I knew I am not supposed to run more than 1 Zorro instance on one account. However, I am trading on 3 sub-accounts using 3 Zorro instances, each instance having its own sub-account. All 3 Zorro instances run on the same computer (a hosted virtual machine), though.

I have 2 questions:
(1) Does this error message actually affect my trading other than being annoying?
(2) If yes, how to prevent it? E.g. do I need to run multiple instances on multiple computers (which would be hard)? Or even at different IP addresses (which can be really hard)? ...

Thanks!!

Yes, it affects your trading. Make sure to use the recent Zorro version, not an old version. Brokers sometimes modify their connection parameters and you need a recent Zorro for catching up.

Thanks. I will try the newest version.

Can you confirm that running multiple Zorro instances on the same machine is not the root cause as long as those instances are each trading under a different sub-account (even if they belong to the same main account)?

I have upgraded to Zorro 1.54 and for 1 day+ the problem didn't show up. So the new version seems to have solved it. Thanks!
