Technical Specifications

CQG software uses the industry standard TCP/IP-based transport and name resolution services supported by Winsock 1.1. Data delivery is via TCP/IP over the Internet.

CQG software consists of 32-bit Windows® applications developed for Intel® X86 architecture computers.

Bandwidth Utilization

CQG software requires approximately 20K bytes/sec sustained and an average 100K bytes/sec of additional bandwidth per user for burst mode. Optimal figures are 60K bytes/sec and 500K bytes/sec.

Because Ethernet performance degrades significantly when the network load exceeds 30%, the number of CQG clients per network segment should be limited to 60, given a normal distribution. CQG software would then consume approximately 2% of the available bandwidth, leaving sufficient reserve capacity for other network functionality.

TCP

System-assigned

2823, 443

 

      All traffic between CQG clients and servers use the TCP protocol. The UDP protocol is not used.

      All network connections between CQG clients and servers are initiated from the client side. No connections are initiated by the server.

      Destination port numbers at the server side are 2823 and 443 (CQG’s registered port number).

      All login transactions are encrypted. All order-related traffic is SSL encrypted. Market data and news traffic are not encrypted.

      Only one simultaneous connection per user is permitted.

Firewalls and Proxies

CQG software supports the following firewall configurations:

      Network address translation

      Dynamically assigned ports on the client side

CQG software supports SOCKS 4, SOCKS 5, and HTTP proxy services as well as a Winsock redirector, such as Microsoft® Proxy Server 2.0.

Following the successful installation of CQG software, you must modify configuration settings in order to connect through a proxy server.

You can make these modifications using the software or by changing the INI files.

Updating Proxy Settings

1.  Open the Login window.

2.  Click the More Options button to display the Select Host, Show Detail, Configure, and Password buttons.

 

3.  Click Select Host.

4.  Select Socks4, Socks5, or HTTP, and define the proxy server host and port.

 

5.  Click OK to exit the windows.

Updating Proxy Settings Using INI Files

CQG software can be configured to work through a proxy server by changing its configuration settings.

Proxy settings are defined in the [NETS] section of two INI files simultaneously and identically:

      cqg.ini (Private folder, by default \Documents and Settings\All Users\Documents\CQGNet\Private)

      cqgclnt.ini (CQGNet folder, by default \Documents and Settings\All Users\Documents\CQGNet)

Make sure that you are not logged on to CQG software when you modify the INI file.

Default values in the INI file are preceded by a colon (:). You should remove those colons when you change default values.

General proxy configuration

Key

Value

Description

ProxyType

<proxy_tag>

one of: {SOCK4 | SOCKS5 | HTTP | None | <any_name>}

default: None

1st (or only) proxy in chain. 'None' disables proxy.

For example, to set up using a single SOCK4 proxy, specify SOCK4 here.

ProxyReplyTimeout

<integer number>

default: 30

Timeout to get through the whole proxy chain.

ServerProxyHost

<string>

must be valid domain name or IPv4

To be supported at a future date. Enables FX Trader-specific “last proxy in chain.” Works even if ProxyType = None.

ServerProxyPort

<number>

default: 2824

To be supported at a future date. CQG software-specific port of server proxy.

 

Settings for specific proxy

Key

Value

Description

<proxy-tag>_Type

one of: { SOCK4 | SOCKS5 | HTTP | None }

Optional if <proxy-tag> is SOCK4, SOCK5, HTTP, or None.

<proxy-tag>_Host

<string>

must be valid domain name or IPv4

Mandatory.

<proxy-tag>_DNS

one of: { 0 | 1 }

default: 0

Optional.

0 = use standard DNS lookup

1 = use proxy for DNS lookup

<proxy-tag>_Port

<integer number>

Optional. Default is type-specific.

<proxy-tag>_User

<username>

Optional. Plaintext username for proxy authentication.

<proxy-tag>_Password

<password>

Optional. Plaintext password.

<proxy-tag>_UseFor

<match> (see below)

default "*"

Optional. Defines matches for target host to use this proxy for. Applied to the TARGET host, not the next proxy in chain.

<proxy-tag>_DirectFor

<match> (see below)

default ""

Optional. Defines matches for target host to SKIP this proxy for. Applied to the TARGET host, not the next proxy in chain.

<proxy-tag>_Next

<proxy_tag>

one of: { SOCK4 | SOCKS5 | HTTP | None | <any_name> }

default: None

Optional. Next proxy in the chain AFTER this proxy.

<proxy-tag>_DirectNext

<proxy-tag>

default: same as <proxy-tag>_Next

Optional. Next proxy in the chain INSTEAD of this proxy. Used if proxy is skipped due to *_DirectFor match.

 

For example, to configure CQG software to use Socks 5 proxy at 172.24.3.144:3128, you should modify both cqqg.ini and cqgclnt.ini, so that they read:

[NETS]

ProxyType=SOCKS5

SOCKS5_Host=172.24.3.144

SOCKS5_Port=3128

# *_UseFor and *_DirectFor are applied to the TARGET host, not to next proxy in chain.

Installation

Because CQG software is a real-time, mission-critical application, we recommend that it and the working directory be installed to a local hard drive.

For best performance, we recommend setting the working directory to a file server and not running CQG software from an application server.

User-modified files are backed up daily by the CQG software and saved locally to the user's hard drive or other location specified in the user settings.

IMPORTANT: User permissions on the main CQG folder and all subfolders and files must be set to “Modify” or “Full Control.” Installing CQG software on a restricted drive and assigning it limited permissions, such as “Read & Execute,” impede performance and may prevent CQG software from working at all.

Entitlements and Permissioning

CQG remotely manages entitlements associated with CQG software. Each user has a specific set of entitlements that are accurately reflected in CQG’s monthly billing. CQG is able to flag customer accounts to prevent any unauthorized entitlement.

CQG Multiple-Monitor Services

CQG offers Dual Monitor Service, Triple Monitor Service, or Quad Monitor Service. Each additional monitor adds an additional amount of bandwidth usage, approximately equal to the figures shown in the above table.
