Why doess Zorro open a Trade and close it immediately (at same time)
Look at SPX500 (third line). The P/L (-5.0) is exactly the spread
The broker would say "Thank you"
And I loose 5 bugs without any reason

It is not the first time I saw this situation

Hi JeyKey II. FYI, I asked this a while ago: http://www.opserver.de/ubb7/ubbthreads.p...true#Post431517.

HTH.

I haven't those trade problems. It seems that the performance and behaviour of Zorro depends on the speed of the VPS its running at.
Since I have more CPU power Z12 takes more trades then before.

The VPS speed has probably not much effect on trading, but the speed of your Internet connection has, and of course your broker.

But for immediately closing a trade the strategy itself is most likely responsible. The Z strategies have no precautions against that - if the stop distance is tight, trades can indeed be immediately closed when the price moves fast in the wrong direction.

I'am not happy with the answer
I don't see a fast/strong move in the wrong direction
Could it be, the stop distance is less then the spread?

No. But it's not necessarily the stop distance, it can also be a normal exit by a different algorithm. If algo A thinks you must buy long and algo B thinks 5 minutes later you must sell short, then a trade can be immediately closed. This is rare, but happens. The algos of Z12 interact and can close another algo's trades under some circumstances.

I can understand that this is not really optimal, but it's implemented this way in the system.

Yepp JCL. I think that the resources of the Amazon free VPS are so low that the connection to the broker could be that bad so that trades won't be taken cause of hitting a threshold. Meaning the difference between the current price and the price Z12 wanted to take trade.

Yes, this is possible when Internet bandwidth is zero or very low. If trades can not be sent to the broker for this reason, the system will place less trades. You'll then see error messages in the window, though.
