update

Hi Spotware,

For some fortunate reason I have not even had a single disconnect during the past 3 days. Its been the first since the last 2-3 weeks.
Hopefully I have not jinxed it with this post

:)

Cheers

Dear Trader,

1) In your experience what could cause the proxy latency to stay the same but server latency to differ between 2 ctrader applications running on the same machine.

There could be various reasons why the proxy latency may differ on two cTrader instances running on the same machine. For example, they might be connected to different proxies. Could you please send us as much information as possible regarding your issue so that we can try to reproduce it? (Connection speed, OS version, etc.)

Could you please press Ctrl+Alt+Shift+T while you experience a huge latency?  It will submit troubleshooting information to our support team.

In addition, could you send us an email at troubleshooting@spotware.com with the exact time, Timezone, Broker’s name, account number right after you submit the troubleshooting information.

2) What could cause one instance of ctrader to login via Amsterdam -2 and the other by London-7.
Note - I am now running 2 instances of ctrader. One instance each on a  different VPS (2 vps in total, both in France), hosted from the same server though.

When you open cTrader, it checks the connection with various proxies and it connects to a random proxy with good latency. Sometimes you have a cTrader instance connected with proxy X and when you open the second instance of cTrader it connects with proxy Y because it has good latency too or because proxy X has bad latency.

 Thankyou for clarifiying.

I have sent an email with with all the relevant information as well as trouble shooting information . Hopefully they will be helpful.

Hi Spotware,

Thanks for the info. Couple more questions  -

1) In your experience what could cause the proxy latency to stay the same but server latency to differ between 2 ctrader applications running on the same machine.

2) What could cause one instance of ctrader to login via Amsterdam -2 and the other by London-7.
Note - I am now running 2 instances of ctrader. One instance each on a  different VPS (2 vps in total, both in France), hosted from the same server though.

Just trying to work out what is causing the disconnect. So far it has been frustrating.
I understand the reasons can vary, however am I right to say that - Perhaps even if server latency is most of the time around 6-10ms only a cross connected VPS ( around 1-2ms server latency) can provide or guarantee a disconnection free environment.

Meaning of journal messages

Hi spotware,

I have a related questions . Can you please explain what is the 'difference' between the following journal entry terms -

1) Disconnected (connection failed)

2) disconnected (slow connection)

Cheers

Dear Trader,

The active workspace is saved when it is closed, either by switching to another saved workspace or closing cTrader. When you close cTrader your Workspaces will be synced with the saved workspaces on the Cloud. Be aware that, when you have multiple instances of cTrader open and you modify the workspace on one instance, depending on which order the instances are closed will affect how the workspace is saved, and can on occasion lead to it becoming corrupted.

 

Thanks , appreciate the information.

CTid

In relation to the disconnects -

Apart from the varying server latencies mentioned above I am wondering whether Ctid syncing or refreshing has anything to do with it due to the workspaces being used. Especially since the same workspaces are being used on 2 different/separate VPS locations.
Because the disconnects seem to also happen at times when I re-login to the VPS. Unless coincidentally a latency/connectivity related disconnect happened at the exact time.

If a workspace contains indicators and if the workspace is saved again on VPS1 , does it reset the indicator on VPS 2 if the same workspace is being used on VPS 2?

So far I have tried various combinations -
 Combination 1 -
c1 - 8 charts with custom indicator
c2 - 20 charts with custom indicator

combination 2 -
c1 - 15 charts with custom indicator

combination 3 -
c1 - 14 charts with custom indicator
c2 - 14 charts with custom indicator

in the above cases c1, c2 etc refers to an individual instance of ctrader running on the same VPS simultaneously/side by side.
In all the above cases workspaces are being used and the same ctid is also being used.

What seems to stand out are or at the least from what i can observe -
1) Same proxy latencies between c1 and c2 ( at times maybe 1ms difference) , however variable server latencies - at times  it is significantly different;similar to the above screen shot.
2) on any given instance of ctrader - proxy latency is the same or stays fixed however server latency seems to vary.
In short -  server latency seems to vary more frequently while the proxy latency remains the same.
3) Disconnects when I re-login to the VPS via RDP and these disconnects are more frequent when there is c1 and c2 running simultaneously within the same VPS.
Disconnects are lower when there is only 1 instance of ctrader running on a single VPS.

As for the CPU on the VPS running 2 instances at the same time, there are 5 cores each at 3.2 ghz and are intel xeons.
Each instance of ctrader takes up lower than 500 MB. There is a lot of spare RAM.

An email has been sent, hope you guys receive it i.e. hope it does not go into the spam folder

edit

A correction needs to be made with regards to the screen shots i.e. c1 and c2.

The yellow underlined server latency is the one with the more CPU intensive indicator (c2 as per the first post).
and
the red underlined server latency is the one with the lower CPU load (c1 as per the first post).

In short -  the higher server latency is being shown on the more CPU intense workspace, don't think that is the reason for the disconnect though.

Apologies for the mix up.


Cheers

RE: Some screen shots

Hi,

I thought I would add a few more screen shots too just to show some information with regards to the significantly differing 'server latency' while being hosted on the same VPS. Infact as can be seen both platforms have been overlaid i.e. c1 and c2 on the same desktop.
Hope these help

First screen shot -



Second screen shot -




Note the time too as per the platform and and computer clock, both of these were taken right after I logged into my VPS again and after  the fresh random( seems persistent now) disconnect.

Cheers

Just to add-  the clock time and visible taskbar is as per my laptop at home. The platform is visible within the resized RDP window used to access the VPS.

Appreciate you trying to help me out. I did try them both out during my numerous attempts. There is more to it i.e. adding data to the 'indicatordataseries' type is different than a 'double' character type which is what the result of 'ask0avgline-bidoavgline' will give. I have not figured this out. In most of the examples  -  an 'index' is used and I do not understand how.
