Market Maker

a simple proof of concept bot for market making using the Deversify API

Running the bot

  • git clone repository
  • npm i
  • yarn start - ignore the TypeScript error: Failed to load tsconfig.json: Missing baseUrl in compilerOptions

The bot will execute every 5 seconds as follows:

  • round starts
  • fetch the latest markets orders using Deversify API
  • create the bids given the latest market orders
  • create the asks given the latest market orders
  • fill orders by iterating through the market orders and finding a match with the created orders
  • display remaining balance
  • round ends

Improvements

  • orders are not partially filled, i.e. once an order is partially filled, the remainder is cancelled
  • matching asks with bids is done randomly, i.e. it should pick the bid which is closest to the ask and vice versa

Initial Conditions

in maket-maker.ts you can change:

  • initial ETH balance
  • initial USD balance
  • percentage of your portfolio that you would like to spend per round
    • a value of 0.1 will spend a maximum of 0.1% of your ETH and 0.1% of your USD
  • percentOffBestOffer - how far you will vary from the current best offer on the market (in percentage)

Run tests

  • yarn test
