F5 project

F5 Project

Finlab Fugle for financial freedom.

This library is not ready for production. It's still under development. The document is not complete, either.

You may need to read the source code sometimes.

Install

pip install f5project

Why?

This library makes it easier to use Finlab/Fugle with other tools together, such as GCF and Github Action.

When deploying your code on GCF. Some troubles come up and you can't just do it like you do on your local machine. This library helps you to solve these problems. It helps you:

• Read config from json file or environment variables.
• Extract Fugle config and certificate from json file or environment variables, dynamically generate them as needed.
• Login Finlab/Fugle with config, which is a little bit annoying because Fugle SDK asks them as files.
• Provide a decorator to make your function a GCF endpoint, without worrying about the request/response format.
• Simulate GCF request locally.
• Sync Github secrets with local config, make CI/CD easier.

Then you can focus on your trading strategy and iterate faster.

Usages

Put all your secrets in .secrets/index.json file and ignore it in .gitignore. It will be synced to Github later.

Add this script and make it a Git pre-push hook. It will sync secrets from local to Github.

"""Sync secrets from local to GitHub.

Install it as a Git pre-push hook by:
`chmod 755 scripts/sync_github_secrets.py ln -s ../../scripts/sync_github_secrets.py .git/hooks/pre-push`

Notes:
1. When you `git push`, it will sync secrets from local to GitHub.
2. It uses `.venv/bin/python` as interpreter, so make sure you have created a virtual environment.
3. Uninstall it by `rm .git/hooks/pre-push`.

You'll also want a CI/CD pipeline to deploy your function to GCF. Here's an example of Github Actions:

.github/workflows/main.yml

on:
  push:
    branches:
      - main

jobs:
  deploy-to-gcf:
    name: "Deploy to Google Cloud Function"
    runs-on: "ubuntu-latest"
    permissions:
      contents: "read"
      id-token: "write"

    steps:
      - id: "checkout"
        uses: "actions/checkout@v3"

      - id: "auth"
        uses: "google-github-actions/auth@v1"
        with:
          credentials_json: "${{ secrets.GCF_SERVICE_ACCOUNT }}"

      - id: "deploy"
        uses: "google-github-actions/deploy-cloud-functions@v1"
        with:
          name: "${{ secrets.GCF_FUNCTION_TARGET }}"
          entry_point: "${{ secrets.GCF_FUNCTION_TARGET }}"
          ingress_settings: "ALLOW_ALL"
          runtime: "python310"
          memory_mb: "2048"
          timeout: 300
          env_vars: >
            FINLAB_API_TOKEN=${{ secrets.FINLAB_API_TOKEN }},
            FUGLE_ACCOUNT=${{ secrets.FUGLE_ACCOUNT }},

            FUGLE_MARKET_API_KEY=${{ secrets.FUGLE_MARKET_API_KEY }},

TODO

• Use pipx to make it easier to have a quickstart template.
• Dynamically generate CI/CD pipeline YAML file, so we can focus on the code.
