Bitfinex Honey Framework Data Server for Node.JS

The HF data server runs backtests for the HF UI Electron App. It syncs candle and trade data and then executes the strategy on it for backtesting.

The DB backend is implemented by a plugin:

• bfx-hf-models-adapter-lowdb

Regardless of the backend, a schema must be specified (providing exchange-specific API methods). The official Bitfinex schema is bfx-hf-ext-plugin-bitfinex.

Installation

For standalone usage:

git clone https://github.com/bitfinexcom/bfx-hf-data-server

npm i

npm run start-lowdb

For usage/extension within an existing project:
