Setup

• Install Docker And Start Postgres Database
  • Once installed, you can start a Postgres container via npm run db_start_dev
  • After starting the postgres container, to run migrations run npm run db_reset_dev
  • npm run db_reset_dev can be ran at anytime to rollback the database
• Set up a .env file in the root server directory
  • There is a .env.example file is provided in the root directory as an example .env file
  • The .env.example should work on *nix and max, but on Windows there is one edit you must make
  • If using Windows, set the DATABASE_URL env variable to your docker-machine IP address
  • Your docker-machine IP can be obtained by running docker-machine ip in the console
• Start the server via npm run dev

About

• For now, the features and design of the frontend is TBD
• Data aggregation is the main focus as of now
• Collecting raw trading data is the ultimate form of market data because anything else (candle data, tickers, charts, etc) can be deduced directly from the trades
• Therefore, currently the focus is on writing modules which can aggregate raw trade data

Todo

• Write Binance API/WS Module
  • ON HOLD
  • Americans can not register for an account, and therefore can not receive an API key
• Write Gate.io API/WS Module
  • ON HOLD
  • Unsure how to handle options and futures
• Write Deribit API/WS Module
  • ON HOLD
  • Unsure how to handle options and futures
• Write Liquid API/WS Module
  • NEED WS IMPLEMENTED
  • REST API implemented, but WS implementation put on hold
  • Looks like I will have to install the Pusher package. It seems complicated to use regular WS packages with Pusher :\
• Write Engine Module To Automate And Orchestrate Keeping Data In Sync
• Write Engine Module To Calculate Candle Data From Raw Trades
  • Runs every X Minutes ??
  • Stored in a separate DB table
• Write Engine Module To Calculate Tickers (Current Prices And Volume)
  • Runs every X Minutes ??
  • Stored in a separate DB table
• Brainstorm Frontend Features
  • Also, Routers And Endpoints Due To Features

Data Composition

Candles are calculated on the day, hour, or minute precisely
