Supports fetching and resizing of candles obtained from Binance. Written as a first foray into Kotlin and Binance's API.
NOT FOR PRODUCTION. Really. This saves candles to a hardcoded folder based on the current working directory for use in the supported resize mode.
You can run this in two modes: fetch and resize.
To fetch candles (for later resizing), you can
use gradle run --args="fetch <pairs>". For example:
gradle run --args="fetch ethbtc ethusdt"
would fetch minute candles for both ETH/BTC and ETH/USDT.
To stop the fetching of candles, use ctrl-c.
To resize candles to a given interval (1 minute or longer), you can
use gradle run --args="resize <pair> <interval>". For example:
gradle run --args="resize ethbtc HOURLY"
would resize all available candles (all that have been fetched by running in fetch mode) into hourly candles. Warnings are printed if the data is incomplete or otherwise missing.
- You must already have the Binance Java API installed. Follow the instructions here to install it. This is somewhat brittle, since the versions aren't pinned with tags.
- Very unconfigurable
- Likely breaks multiple Kotlin idioms and best practices
- Minimally (unit/integration) tested
