A simple library for simulating markets in Python
PyMarket is a python library designed to ease the simulation and comparison of different market mechanisms.
Marketplaces can be proposed to solve a diverse array of problems. They are used to sell ads online, bandwith spectrum, energy, etc. PyMarket provides a simple environment to try, simulate and compare different market mechanisms, a task that is inherent to the process of establishing a new market.
As an example, Local Energy Markets (LEMs) have been proposed to syncronize energy consumption with surplus of renewable generation. Several mechanisms have been proposed for such a market: from double sided auctions to p2p trading.
This library aims to provide a simple interface for such process, making results reproducible.
import pymarket as pm import numpy as np r = np.random.RandomState(1234) mar = pm.Market() bids = pm.datasets.uniform_bidders.generate(20, 20, 1, 1, r) for b in bids: mar.accept_bid(*b) mar.plot()
Access the bids
bids = mar.bm.get_df() bids.head()
quantity price user buying time divisible 0 0.2374 1.0234 0 True 0 True 1 0.1784 1.1770 1 True 0 True 2 0.6301 1.5789 2 True 0 True 3 0.1600 1.8008 3 True 0 True 4 0.7920 1.5478 4 True 0 True
Run a market algorithm
transactions, extra = mar.run('p2p', r=r) transactions = transactions.get_df() transactions.head()
