    Parameters in square brackets are optional.

    Otherwise, configuration of LoadBalancing and/or FaultTolerance (please, check corresponding classes)
  * **port** ([*int*](https://docs.python.org/3/library/functions.html#int) *,* [*str*](https://docs.python.org/3/library/stdtypes.html#str) *,* *optional*) -- The port number of the remote tick-server.

### Examples

Specify host name and port together in first parameter:

```pycon
>>> session.use(otp.RemoteTS('server.onetick.com:50015'))  
```

Additionally specify websocket protocol and resource of the remote server:

```pycon
>>> session.use(otp.RemoteTS('wss://data.onetick.com:443/omdwebapi/websocket'))  
```

Combination of LoadBalancing and FaultTolerance can be used for host parameter:

```pycon
>>> RemoteTS(FaultTolerance(LoadBalancing('host1:4001', 'host2:4002'),
...                         LoadBalancing('host3:4003', 'host3:4004')) 
```
