Learn how to use pure market making strategies

How it Works

In the pure market making strategy, Hummingbot continually posts limit bid and ask offers on a market and waits for other market participants ("takers") to fill their orders.

Users can specify how far away ("spreads") from the mid price the bid and asks are, the order quantity, and how often prices should be updated (order cancels + new orders posted).

Warning: Please exercise caution while running this strategy and set appropriate kill switch rate. The current version of this strategy is intended to be a basic template that users can test and customize. Running the strategy with substantial capital without additional modifications may result in losses.

Schematic

The diagram below illustrates how market making works. Hummingbot makes a market by placing buy and sell orders on a single exchange, specifying prices and sizes.

Prerequisites

Inventory

  • You will need to hold sufficient inventory of quote and/or base currencies on the exchange to place orders of the exchange's minimum order size.
  • You will also need some ETH to pay gas for transactions on a decentralized exchange (if applicable).

Minimum Order Size

When placing orders, if the size of the order determined by the order price and quantity is below the exchange's minimum order size, then the orders will not be created.

Example:

bid order amount * bid price < exchange's minimum order size
ask order amount * ask price > exchange's minimum order size

Only a sell order will be created but no buy order.

Basic Parameters

We aim to teach new users the basics of market making, while enabling experienced users to exercise more control over how their bots behave. By default, when you run create we ask you to enter the basic parameters needed for a market making bot.

See Advanced Market Making for more information about the advanced parameters and how to use them.

The following parameters are fields in Hummingbot configuration files located in the /conf folder (e.g. conf_pure_mm_[#].yml).

exchange

The exchange where the bot will place bid and ask orders.

Prompt:

Enter your maker exchange name

market

Token trading pair symbol you would like to trade on the exchange.

Prompt:

Enter the token trading pair you would like to trade on [exchange]

bid_spread

The strategy will place the buy (bid) order on a certain % away from the mid price.

How far away from the mid price do you want to place the first bid order?

ask_spread

The strategy will place the sell (ask) order on a certain % away from the mid price.

How far away from the mid price do you want to place the first ask order?

minimum_spread

The strategy will check every tick and cancel the active orders if an order's spread is less than the minimum spread parameter.

Prompt:

At what distance/spread from the mid price do you want the orders to be cancelled?

order_refresh_time

An amount in seconds, which is the duration for the placed limit orders. The limit bid and ask orders are cancelled and new orders are placed according to the current mid price and spreads at this interval.

Prompt:

How often do you want to cancel and replace bids and asks (in seconds)?

order_amount

The order amount for the limit bid and ask orders. Ensure you have enough quote and base tokens to place the bid and ask orders. The strategy will not place any orders if you do not have sufficient balance on either sides of the order.

Prompt:

What is the amount of [base_asset] per order? (minimum [min_amount])

ping_pong_enabled

Whether to alternate between buys and sells.

Prompt:

Would you like to use the ping pong feature and alternate between buy and sell orders after fills?

Tip: For autocomplete inputs during configuration, when going through the command line config process, pressing <TAB> at a prompt will display valid available inputs.
