The configuration consists of three sections: TCP connection information, multicast groups, and market types definitions.
An application can work with multiple environments, (for example, UAT and Production). Each one has its own destination and source addresses.

...
All TCP messages including requests and responses are defined in ICE iMpact Multicast Feed Message Specification.
The static data can be received from ICE or loaded from a file configured with IceImpact::InstrumentLoadParams::filename. Acquiring static data occurs before processing multicast Market Data messages.
Multicast Groups
Multicast groups are for defining multicast feed channels for different markets.

Troubleshooting
ICE is dropping non-secure TCP connections / ICE iMpact Market Data handler doesn't receive data from
...
port 3000
...
root causeRoot Cause
ICE requires TLS connections to their market data feeds and drops non-secure connections.
By default, port 443 is used for secure TLS connections and port 3000 is used for non-secure connections.
...
Encrypt connection with other proxy applications (e.g. STunnel) and forward a non-secure connection from localhost:3000 to <ice TCP feed>:443.
For example, the next first configuration should be changed to the second one, also using the given STunnel configuration.
Old configuration:
| Code Block | ||
|---|---|---|
| ||
<tcp ip="63.247.112.185" port="3000"
userName="Username"
password="Password"/> |
with the following oneNew configuration:
| Code Block | ||
|---|---|---|
| ||
<tcp ip="localhost" port="3000"
userName="Username"
password="Password"/> |
and STunnel configuration:
