mango-explorer
provides Python code to interface with Mango Markets, along with a functional marketmaker.
mango-explorer
is available as a Python package on Pypi and can be installed as:
pip install mango-explorer
A simple installation walkthrough is available, and of course other ways of installing it or adding it as a dependency are possible and will depend on the particular tools you are using.
mango-explorer
is also available as a docker container with the name opinionatedgeek/mango-explorer-v3.
The latest version of the code is in the main branch on Github.
Code to integrate with Version 2 of Mango is in the v2 branch.
Here's a brief but complete example of how to place and cancel an order. This example is runnable in your browser!
import decimal
import mango
import os
import time
# Load the wallet from the environment variable 'KEYPAIR'. (Other mechanisms are available.)
wallet = mango.Wallet(os.environ.get("KEYPAIR"))
# Create a 'devnet' Context
context = mango.ContextBuilder.build(cluster_name="devnet")
# Load the wallet's account
group = mango.Group.load(context)
accounts = mango.Account.load_all_for_owner(context, wallet.address, group)
account = accounts[0]
# Load the market
stub = context.market_lookup.find_by_symbol("SOL-PERP")
market = mango.ensure_market_loaded(context, stub)
market_operations = mango.create_market_operations(context, wallet, account, market, dry_run=False)
print("Initial order book:\n\t", market_operations.load_orderbook())
print("Your current orders:\n\t", market_operations.load_my_orders())
# Go on - try to buy 1 SOL-PERP contract for $10.
order = mango.Order.from_basic_info(side=mango.Side.BUY,
price=decimal.Decimal(10),
quantity=decimal.Decimal(1),
order_type=mango.OrderType.POST_ONLY)
placed_order = market_operations.place_order(order)
print("\n\nPlaced order:\n\t", placed_order)
print("\n\nSleeping for 10 seconds...")
time.sleep(10)
print("\n\nOrder book (including our new order):\n", market_operations.load_orderbook())
print("Your current orders:\n\t", market_operations.load_my_orders())
cancellation_signatures = market_operations.cancel_order(placed_order)
print("\n\nCancellation signature:\n\t", cancellation_signatures)
print("\n\nSleeping for 10 seconds...")
time.sleep(10)
print("\n\nOrder book (without our order):\n", market_operations.load_orderbook())
print("Your current orders:\n\t", market_operations.load_my_orders())
Many more examples are provided in a separate Github repo and can be run in your browser (no installation required!) at Binder.
There is a Marketmaking Quickstart - a walkthrough of setting up and running the marketmaker on devnet, from setting up the account, depositing tokens, to running the marketmaker itself.
It can take around 30 minutes to run through.
Requirements:
- A server with docker installed
Note This walkthrough is devnet-only so no actual funds are used or at-risk.
🥭 Mango Markets support is available at: Docs | Discord | Twitter | Github | Email
