Presentation

A simple market making bot using DeversiFi to get orderbook data and place n bid/ask orders every x seconds regarding best bid/ask within a certain price range and balance size percentages. It will automatically cancel orders out of a maximum price range percentage.

This code is dynamic enough to add trading pairs right now. At the moment only ETH:USD is supported.

Work to do:

• place real orders;
• make each bot configurable to the user (delay between orders, number of bid/as orders per loop, maximum price ranges, etc.);
• add more trading pairs;
• add more tests;
• test performance.
