Arbitrage

Learn how to use Arbitrage strategies

How it Works

Arbitrage is described in Strategies, with a further discussion in the Hummingbot white paper.

Schematic

The diagram below illustrates how arbitrage works. The transaction involves two exchanges: Exchange A and Exchange B. Hummingbot monitors the prices on both exchanges and transacts when a profit opportunity arises.

An opportunity arises when Hummingbot can buy on one exchange at a lower price and sell on the other exchange at a higher price.

Prerequisites: Inventory

  1. Similar to cross-exchange market making, you will need to hold inventory on two exchanges (a primary and secondary exchange), in order to be able to trade and capture price differentials (i.e. buy low on one exchange, sell high on the other).
  2. You will also need some Ethereum to pay gas for transactions on a DEX (if applicable).

Basic Parameters

The following walks through all the steps when running create command. These parameters are fields in Hummingbot configuration files (located in the /conf folder, e.g. conf/conf_arb_[#].yml).

primary_market

Enter an exchange you would like to trade on.

Prompt:

Enter your primary spot connector
>>> binance


secondary_market

Enter another exchange you would like to trade on.

Prompt:

Enter your secondary spot connector
>>> kucoin


primary_market_trading_pair

Enter the token trading pair for the primary exchange.

Prompt:

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


secondary_market_trading_pair

Enter the token trading pair for the secondary exchange.

Prompt:

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


min_profitability

Minimum profitability target required to execute trades.

Prompt:

What is the minimum profitability for you to make a trade?
>>>


use_oracle_conversion_rate

Rate oracle conversion is used to compute the rate of a certain market pair using collection of prices from either Binance or Coingecko.

If enabled, when the trading pair symbols mismatch, the bot will use a real-time conversion rate from the oracle. For example, if markets are set to trade for LINK-USDT and LINK-USDC, the bot will use the oracle conversion rate between USDT and USDC.

You can also edit it from config_global.yml to change the rate_oracle_source.

Prompt:

Do you want to use rate oracle on unmatched trading pairs? (Yes/No)
>>>


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

Advanced Parameters

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

secondary_to_primary_base_conversion_rate

Specifies conversion rate for secondary quote asset value to primary quote asset value.

secondary_to_primary_quote_conversion_rate

Specifies conversion rate for secondary quote asset value to primary quote asset value.

Exchange Rate Conversion

From past versions of Hummingbot it uses CoinGecko and CoinCap public APIs to fetch asset prices. However, this dependency caused issues for users when those APIs were unavailable. Starting on version 0.28.0, Hummingbot uses exchange order books to perform necessary conversions rather than data feeds.

When you run strategies on multiple exchanges, there may be instances where you need to utilize an exchange rate to convert between assets.

In particular, you may need to convert the value of one stablecoin to another when you use different stablecoins in multi-legged strategy like arbitrage.

For example, if you make a market in the WETH/DAI pair on a decentralized exchange, you may want to hedge filled orders using the ETH-USDT pair on Binance. Using exchange rates for USDT and DAI against ETH allows Hummingbot to take into account differences in prices.

maker_market: bamboo_relay
taker_market: binance
maker_market_trading_pair: WETH-DAI
taker_market_trading_pair: ETH-USDT
secondary_to_primary_base_conversion_rate: 1
secondary_to_primary_quote_conversion_rate: 1

By default secondary to primary base conversion rate and secondary to primary quote conversion rate value are both 1.

Our maker base asset is WETH and taker is ETH. 1 WETH is worth 0.99 ETH (1 / 0.99) so we will set the secondary_to_primary_base_conversion_rate value to 1.01.

While our maker quote asset is DAI, taker is USDT and 1 DAI is worth 1.01 USDT (1 / 1.01). similar to the calculation we did for the base asset. In this case, we will set the secondary_to_primary_quote_conversion_rate to 0.99.

To configure a parameter value without going through the prompts, input command as config [ key ] [ value ]. These can be reconfigured without stopping the bot however, it will only take effect after restarting the strategy.

config secondary_to_primary_base_conversion_rate: 1.01
config secondary_to_primary_quote_conversion_rate: 0.99
