Release Notes - Version 0.16.0¶
hummingbot version 0.16.0! This release includes updates with pure market making strategy, more documentation for developers, fix for known Huobi bugs in the previous release, and announcement with our active bounty program.
🏆 Harmony Protocol $ONE Makers program extended¶
Great news! We're happy to announce that Harmony Protocol has decided to extend the $ONE Makers program to October and beyond! Users can continue to earn rewards by market making for Harmony's ONE token on any supported exchanges where it trades.
We will keep the rewards schedule the same for October.
🏃 Penny jumping mode in pure_market_making strategy¶
After you have placed an order, have you seen other orders respond by making their price slightly better than yours? This is called penny-jumping, and it can be a good way to ensure that your orders have the highest probability of being filled while maximizing the profit upon a fill.
With pure market making strategy (in single order mode), users now have the option to automatically adjust the prices to just above top bid and just below top ask. See this page for more information.
💵 Transaction costs in pure_market_making strategy¶
We have conformed how transaction costs are handled across all strategies. By default, the pure market making strategy now incorporates transaction costs like exchange trading fees and gas costs into order prices.
This is a configurable parameter, so users can turn this behavior off if they like. See this page.
📝 More developer documentation¶
As part of our ongoing efforts to make the Hummingbot code base more understandable and easier to use for developers, we have published guidelines for community-contributed exchange connectors, as well as more documentation on the order lifecycle:
- Guidelines and expectations for community developers building exchange connectors
- Order lifecycle and market events for connectors
- Changed MarketSymbolPair to MarketTradingPairTuple in strategies for creating and cancelling orders
