Ray client installation#
This section describes installation and configuration of Ray client, which is necessary to run
onetick.py code remotely on a Ray instance.
You don’t need it, if you use
onetick.py locally with fully installed OneTick, as mentioned above.
Commands in this guide are expected to be run on Linux.
Some changes must be made to run them on Windows.
For example, on Windows
export command should be replaced with
set and quotes should not be used.
Ask your OneMarketData rep for a username and password, also ask for onetick-py version in your environment (ex: 1.62.1). Then run the commands below (replacing USERNAME, PASSWORD and OTP_VERSION with your values):
pip install -U --index-url https://USERNAME:PASSWORD@pip.distribution.sol.onetick.com/simple/ onetick-query-stubs onetick-py==OTP_VERSION
To simplify Ray initialization in the future, add a new environment variable with Ray instance URL (ask your OneMarktData rep):
Now you can start coding in your IDE and you could do
import onetick.py as well.
But you can’t run your code locally, because you don’t have OneTick installed.
To run your code remotely on Ray, proceed to Remote OTP with Ray for details.
Connection to Ray#
In order to connect from an external network, it is necessary to whitelist your IP address and use your connection certificates (ask your OneMarketData rep to provide certificate files and whitelist your IP). Download these certificate files to one common folder (<path-to-folder>):
Add paths to certificate files into environment variables:
or in the similar way for Windows.
Now you can connect to a Ray instance from an external network.
